I think theres not much difference from using artificial lighting or the sun except sun is more efficient in generating green water. And most importantly, its FREE  tongue.gif

Actually there is an important specification to look out for when selecting an artificial light source to keep green water -- the colour temperature must emulate natural day light as closely as possible. Look for a lamp with a output of between 6,500 Kelvin to 10,000 Kelvin. Anything less than 6,500 kelvin will be yellowish, while above 10,000 Kelvin too blueish.

I can't remember who... but recently a fellow member was getting nitrite reading in his green water, and I suspect without much investigation that it's due to his Metal Halide lamp producing less than 6,500 Kelvin. If you ever try to keep outdoors plants indoor by beaming it with very "bright" (but yellowish) incandscent lamp (about 3000 Kelvin only), you'll find your plants die because you didn't provide enough "sunlight" although the lamp is "bright". On the other hand, the same plant can probably survive longer if you provide it with a not-so-bright flourence lamp with a "daylight" rating.

To find out more... Osram has brochures that explains light colour:-

Could be. I hv transfered my three 2" goldfish to a guppy tub filled with 130L of water. Thats way way underload. I hope the green water wont turn brown due to lack of ammonia.

green water won't turn brown because of low ammonia. It simply won't get intense.

If your tub is getting enough sunlight but not enough ammonia due to low stock level, then solve the later problem by creating ammonia artificially such as letting excess pellets to rot in the water. Just make sure you replensih the artificially created ammonia constantly, ie, keep topping up with new pellets. I think it should work....

Wah, you champion. That sounds like a quartz security lamp, isn't it? I won't doubt your setup but it goes completly against what I understand. cry.gif Strange....

Hmm... come to think abou tit, those quartz security lamp can be bought for just $50-$60. It may be an alternative for some bros here to try.

better not. It's not easy to control low powered lamp. Just information that as long as there is light, somewhat sufficiently for the unicelluar algae to grow.

It will work for sure. But im afraid too much uneaten food will cultivate bacteria and fish will fall sick sooner or later.

My first try was a 6cm goldfish in a 130L water of guppy tub. It took 2 mths for the water to become green. I still do 90% water changes weekly even b4 the water turns green. After the water turns intense green which is 2 mths later, i continue the normal routine of 90% water change weekly. But then, the green seems to disappear. Ammonia and nitrite will spike mad.gif . I think i believe i did wrong was, i only ON my 150W MH light for 6 hrs. goldfish doesnt seem to like the bright light leh, so no choice got to shorten the photo period. It always remain stationary at one corner until the light goes off.

Im monitoring this time with underloading of goldfish whether the green will "dissappear". But this time, hehehe, i ON the MH light for 10 hours.

CK, let's address some of your issues...

those china farms under hot sun, do they use shades ? Who cares if the goldfish scare of light. Why so KS ? Important is to get the sufficient amount of light.

If you afraid of uneaten food, then feed little and increase frequencies. U using timer or not ?

If taking 2 mths to turn green, then u got a major problem. If the green tends to disappear, you got even bigger headache. No wonder your NH3 and NO2 moving upwwards.

2 months is too long for green water to kick start. You should check your setup. How is your setup like? Did you have a filter in it? Your main problem is the "method" which you've used to kick start the green. Before the green begins to kick in, the water will need to pass through a state of high waste level. You shouldn't change water at this time because the waste level is what's needed before the green finally kick in. Yes, fish will be stressed here but there's nothing else that could be done.

I would also suggest using lesser water if you want to use the "with fish" method. Typical 4 inch fish will only need about 40litres of water. I would suppose that your MH light is the type that's available in the market and strong enough (10,000K) to simulate (cloudless) sunlight. So 6 hours per day is definitely more than enough. For a virgin brew, you need to use a smaller volume of water. I have used 40L of water for two 2-inch fishes. And now whenever I need to cultivate virgin brew, I will use "fishless" method which only need 3L of water. Using PL lamp with 24hours of operation and a lot of pellets for the waste spike, I will be able to get intensely green water in just 4-5 days.
cktan
Thats what i think also. 2 mths very long hoh. Alvin Lim advice me on the setup leh. Shouldnt be wrong right? No filter, only an airstone, with a 10cm Ranchu inside. Light op is 150W 10,000K bulb hang at 35 cm above water level surface. I cannot reduce the water else the water level in the tub will be less than 20cm and goldfish might get "burned" by the strong light. Changing 90% water weekly till water turns green also taught to me by Alvin. Sh be ok, just that this way, green will kick in much much longer. But he did warn me that tub is underloaded and might take some time for green to kick in. Aiii, end up, green didnt come in but high ammonia and nitrite came sad.gif

Anyway, im satisfied with my 2nd try. 2 weeks to get intense green. I think the receipe is to overload the tub, more hrs of lighting and seeding back 50% of water instead of 10%.

By the way, did u ever test yr green water for nitrite say after 5 days?

China one i didnt see shade. Jap goldfish breeder i did see them use shade. The goldfish very pitiful leh. Hide one corner and can remain that way the whole day without moving much. But once the light goes off, it then start to swim around, dart about actually (if u know what problem im having). Weird fish.

I got timer. As i said, food poured out but goldfish always remain at the one corner. Even if food pour in front of it, it wont eat much. I saw it took > 3 hours to finish just 2 clicks of food with lights on. Simply not interested in food.

The goldfish often dart and scratch at tub bottom. See already also heart pain. For dunno what reason it behave that way. End up 3 mths later. It float midway, body slanted to one side while at rest, and hv difficulty eating floating pellets. It eat floating food by tilting its body sideways. I returned this poor goldfish to its owner and he said its normal sad.gif .

My current Gfs darting behaviour still unsolved till now. cry.gif

More issues to address isn't it ?

Pitiful for the fish ? Goodness .... u very the angmo pie leh.

Since you got advices, why didn't u seek further clarification ?

Darting around usually due to stress. If your present fish still in such manner, better try to find out why before you attempt further "experiment" on the poor fish.

A 10cm fish in a blue tub fill up to 20++cm ... understock. No wonder 2 months lah. But of course, you could have seek for help instead of waiting 2 months. Have you ? Anyone advice you that your bulb is over-rated ?

Most test kits do not have the capability to test green water. U might need to use the stripes type or that .... sharks what brand again ... someone help me out ...

Darting around is due to stress. Hehehe, thats what i think so. I think u hv to convince Alvin darting around is due to stress. I told him and he said its normal. What can i do? Where got normal fish eat half way then all of a sudden dart to another corner of the tub and then afraid to go back to that corner to eat?

Im experimenting on feeder goldfish. Those are meant to be in bigger fish mouth. If i havent taken them back, they would hv been dead by now. Only certain type of fish will die in my tap water. Sucker fish is one of them.

Aii, lets not dwell on this topic. Its still a mystery.

hahahaha ... u go disturb the fish when it is eating har ? no wonder dart lah. It can be stress by something else instead of your water or lamp .... sometime u just got to figure that out. It is normal to see it if the fish got shock. Anyway, a single fish of course lah. U try 2-3 fish u won't see it.

Dun waste time on feeder fish.

Aii.. u think koi ah? can train to come to u for food? goldfish r not as smart le..
one huge giant that it can sense the vibration a metre away, casting a shadow into the water.. if i'm so small like the fish, sure get freaked out as well, the more u disturb, the more the fish can't settle down..

i'll definately get freaked out if i see a strange object the size of a boeing 777 suddenely appearing on top of me..

y u playing with feeder fish? *faint* i got a few fishes that i need to get rid off, too many fishes, no space, u wanna adopt?

I have no doubt with Mr Alvin Lim's teaching. But did you RECEIVE his instructions procedures correctly?

Firstly, We are talking about VIRGIN BREW here. FIRST BREW. Meaning, cultivating Green Water from SCRATCH... with NO SEEDING AT ALL. You start with CLEAR WATER (de-chlorinated/de-chloramined).

For VIRGIN BREW, if you keep changing the water before it turns green FOR THE FIRST TIME, you'll take a very very long time for the algae to actually kick start. I would say, taking 2 months with your method, is considered FAST already. For your success, I credit it to the strong MH lamp that you're using. If you have been using PL lamp with that method of 90% weekly change (before even seeing first sight of green), it will probably take FOREVER. Trust me, if you have waited, say another 2-3 days (after that one week) the algae would have kicked start. But after you do that 90% water change, you SEMULAH (back to square one) everything! You see... you have wait 7 days to change water... you might as well wait for another 2-3 days for the algae to finally kick in. Make sense? Of course the guildline of "8 to 10 days" was applicable to lesser water volume like 40 litres or so. One of the reasons why there's no filter for virgin brew (after virgin brew, you might want to play with BIO-GREEN or FILTER-green water or dunno-wat-green, etc which some experts here are already playing with), is that you need to "create" the neccesary waste level before algae kick start. So it makes more sense for you to have LOWER WATER VOLUME.

If you're worried about stressing your fish with the method written by HB, which I referred you to earlier, you might want to try the fishless method. HB once did successfully OUTDOOR. I experimented also successfully with just PL lamp, INDOOR. For the 3rd time I did it, I was able to achieve intense green water in just 5 days.

I believe Alvin was telling you to do that "weekly 90% change of green water" AFTER your VIRGIN BREW stage. That's when you've got green water seed already. With seeding, your green water culture will start in less an hour or so, with exposure to the necessary light intensity (preferrbly above 6000K). So you will NEED change your green water every weekly or so.

Im standing more than 3m away from the tub. Sometimes, i hide myself in one corner of the room. goldfish so smart meh? Can see me 3m away? I know base on Physics, their eyes can see at most 180deg. But at an angle im observing the goldfish, it is not possible for the goldfish to hv seen me.

My first try after i moved to my new house was 2 baby thai ranchu. Just 2 weeks, both floated. Both however are still alive and with me. 1.5 years old liao.

Second try was another pair of Thai Ranchu given to me by a Ozeki member, one floated and the other half floated in just 1 mth.

I can only think of it this way. My house is relatively new and is already 4 years old. I hv stayed there for only 1.5 years. And when i moved in there, the block is only 20% filled. So for the past 3.5 years, the block occupancy rate is very low. Naturally, the water tank refresh rate in the block is also very low. Some hv said aging water for too long results in "dead" water and even arrowana put in such water will die. So its like theres alot of bacteria/parasite in the stupid water tank.

Another thing i notice is, there is no trace of chlorine in my tap water. 8 mins walk to Jurong Point and i notice the water there has chlorine content.

One thing for sure. It is definitely stressed by my water. All my fish dart. Even cardinals, cories which didnt happen until i moved to this new place. Only sucker fish will die.

Aiyoo, no chlorine good meh? beg2.gif Whats the primary purpose of chlorine?

I think i really deserve the Champion title leh peace.gif . Testing Jurong pt water is just one of the many things i hv done. Others include:
1) Write to water dept and complain
2) Call them up personally as well
3) Transport water from my company and test it on the feeder goldfish
4) Boiled my house tap water.
5) Test my frend living in another blk for Chlorine.
6) Spend $100+ just to test my tap water. End up OK. Sian... But testing the water is not just for the fish. I hv 3 attack cases of stomach flu when i moved in to the new house. Now ok liao leh. Hehehe, maybe my body immune to the water bacteria/parasite liao.
7) And many other crazy things that i can think of....

goldfish still occasionally dart abt. But i can see the fishes behaving much better as compared to those a year ago. Now the house is abt 98% occupied. By sometimes some couples just come on weekends (u know do wat lah). I hope they moved in here quick and help to flush some water.

I hv one pioneer goldfish which will always gulp air after each meal. Gulp so much that it will float after that. Poor goldfish. Suffer like that for 1.5 yrs liao. But still didnt die. Maybe i will capture a video clip of it in suffering and show u bros here.

green water start liao. No problem this time. good.gif . Now the feeder goldfish in green water. So, 3 m away cannot see anything liao. smile.gif . In a way also good. I no need to bother abt them. But i did saw one always gulp for air after each meal. I think this one hv potential to float ohmy.gif .

There is a WHO water standard that sh be followed. Chlorine is added at the water treatment site to kill off bacteria/parasite. The amt sh be large enough so that residual chlorine level at the consumer site must exceed ???mg/l but must be less that ???mg/l. SOrrie, forgot how much.

So if you trust WHO's guideline and also PUB is up to WHO's standard (at least we are still alive and reading forum), you can be sure the H2O is good.

Im sorry. That is exactly what Alvin told me to do. To change 90% water weekly until water turns green. If u dont believe me, u can quote my words to him. he did mention that due to underloading of the tub, green might not take place.

I don't call Alvin for trivial things as such. I am merely telling you that you can achieve green water with your very good setup (except the water volume part) by doing the following:
- Use lesser water.
- wait for about 10 days with no water change you see green.
- Fish will be stressed but since you say is feeder fish, why not?

Since you said that Alvin told you "your tank is understocked", my understanding is, he is telling you to "reduce water volume". Pls also ensure that you have a healthy fish.

We have so many articles here on how to set up Indoor green water. And so many bros wrote their experiment with illustrations. I don't think there's any other goldfish forums having materials of such completeness on INDOOR green water.

I also say again for the 3rd time... You can achieve green water indoor even without fish.. if fish stress is what you worry about.

Just do a search and read through, pls.

Errr, before i started on my very first post here, i have already read up 80% of the stuff in RG. My first experiment with the green water tingy was months ago before i even discover RG. So yes, if i had know abt fishless creation of green water, i will definitely go for that method.

Despite him knowing my tub is understock, he still ask me to fill my tub with water to the brim. I understand his concern as i believe he is afraid the goldfish might get burned by the light.

goldfish was healthy. Lend to me by a Ozeki member. I hv returned the goldfish back to him 3 mths ago.

When I first shifted to my present house, only 16 out of 300 families. And when pple are knock their walls down and laying their tiles, I already shifted in enduring the daily noise.

Dun get too nervous about all these factors. Like I said, nothing is a mystery. If there is a problem, there is a solution.
