And what's the reason for max airflow ? I thou BB cannot withstand too high water current ?

I'm quite sure BB can withstand the current generated by a sponge filter. Afterall, the current is relatively weak compared to that inside a typical OHF where many owners often proudly brag about flow rate of thousands of litres per hour! ohmy.gif

QUOTE(:0 @ sad.gif)
By over-stocking, maybe we are putting in 2-3 GFs per 100 litres, therefore we would need a higher amount of BB to break down all the waste generated but does this perception/assumption really works ?

You assumed correctly; just cultivate more BB to accomodate an overstocked tank. It implies as you add more fish, all you need to do is add more filters.

Unfortunately, this view is seriously flawed.

You overlooked one fact about the nitrogen cycle. Although you can convert more ammonia (produced by higher fish load) by adding more filtration, the end result is you get more nitrate. Although relatively harmless compared to ammonia, long term exposure to high nitrate concentration (in excess of 10-25 [some say 50] ppm) is said to stunt your fish.

So now with high stock level and more filtration, you need a way to get rid of nitrate. Although you can add plants which takes in nitrate as nutrients, the best way is to change water to discard the nitrate laiden water.

So your answer as to how do hdb dwellers keep overstocked goldfish tank can be sum up as "change water frequently". biggrin.gif

You can read up about the accumulative nature of nitrate in the excellent article, My Journey with Nitrates. I hope you will comprehen it fully and come to the conclusion that the way things go, sparsely stocked tank filtered by sponge filters accompanied by diligent water change is the only way to go if you don't just want to keep your goldfish alive but to groom and let it grow to its maximum potential.

And finally I want to add one thing about the need to keep lots of goldfish...

Do ask yourself why is there a need to keep so many goldfish to the extend you know you're overstocking your tank? Wouldn't keeping an amount that you can manage (50-100 litres per fish) be better? I'm quite sure it's fun and exciting to have 45 dogs and puppies in your living room. But I hope you'll have enough time to bath them, feed them, walk them etc. In any case, your 45 pets will probably not be healthy or at their best form becoz you only have that much time and money to spend on your pet.

But of course, I know you'll have better sense and max out at maybe 2 doggies if you live in a flat. Thank goodness for common sense.

So why not apply the same thot when you keep goldfish in your 4 feet tank? unsure.gif

There is not ideal stocking level. Usual figure such as 1GF to 10gals are general guidelines. If you are confident enough, you can always stock higher.

The above points are for keeping the fish alive only. If you are concerned about other issues (eg growth, health ), that's a totally different ball game...

Another guideline we usually see on the web is that cycling will take 1 month. again this depends on many factors.

i read sq guy thread at AF on nitrate. last week i measure NO3 and shocked to see that it hit 80 ppm. this week it hit 100 ppm. after performing 20% water change, still measure at 100 ppm.
why i do a check ? bec i see all the goldfish eyes seem to get bigger and bigger when i compared with the photos i first got them.

since i am using sump tank. i bought 4 of those guanhin plant (guan Inn teck in teachew) and place them at the last compartment. hopefully this will lower down the nitrates. will be getting those floating aq plant as backup. hopefully this will remove the nitrate with 20% water weekly change

if it don fall to 40ppm; the next move may be to buy "tetra nitrate minus". (as stated, it is a one time application)

anyone buy before; how much?

yur tank prob got nitrate readings higher than 100 ppm, but your test kits can only measure up til 100 ppm. Therefore, the amount of water change you performed was not enough to bring it down significantly. 20% is very little. at 100ppm, i would have sugguest you do a 80%. follow by continual small changes the next few days to really bring it down.

This is for whtan...

100 ppm of nitrate is way off any safe guidelines for goldfish.

Since you have a fresh nitrate test kit, put it to good use and do the following:-

Replace 100% of the water, including those in your sump tank. Be careful not to kill your BB.

Test the nitrate level. It should be zero.

Repeat the test 24 hours later. It should be positive (let's assume it's 10 ppm). Do not change any water.

Repeat daily for 7 days. If it was 10 ppm a day after water change, it will read 70 ppm. Nitrate accumulates.

Since your water is 1 week old, you would change 20% (like you said earlier) right? Fine. After this 1st week's water change, your nitrate level is down to 80% of 70 ppm = 56 ppm. Afterall, you discard 20% of the nitrate when you changed water. Woo hoo!

On the 8th day (since you changed 100%), your nitrate will be 56 ppm + 10 ppm = 66 ppm (which is 4 ppm less than yesterday ah!)

On the 9th day, it'll 76 ppm.

On the 14th day, it will be 126 ppm.

By the 2nd week since you changed 100%, most test kit no longer register the nitrate level since it's above 100 ppm. I think that's a bloody obvious clue to you that anything more than 100 ppm is... erm... outrageous?

What're my points?

1. Always stock correctly.
2. Always test your nitrate level in an established tank to work out how long the water can last in that setup.
3. green water dun have nitrate. biggrin.gif
4. Ever consider keeping demekins with jumbo size eyes?

in order to last till nxt wk, i ve
: started planting compaign in sump today. a less taxing and easier solution to alleviate the problem.
: will do another 30% change to see any changes to bring the ppm now. no energy to do a 100%.

alr check out the tetra website b4 posting. someone has tested it in AF experiment.
while it may not be a lobang buy, anyone has used it effectively before full scale here and verify its effectiveness? that is one more brand from Seachem, PRIME claim it can detoxify nitrate also.

Just a show case:

got one day not toooo long ago me think i so smart(kenna smack more like it)lazy to mix + wanna give my gfs a salt bath for all of them.THROW lots of salt into tank WITH the canister running(think that flow would melt salt faster.).

guess wat........yup all my bbs mati

2nd day water cloudy thought overfeed.Did a 80% water change stop feeding.Again water cloudy---THEN something struck me alamak my bbs my babies!!!!!!!

Did a 80% water change every other day.guess wat sala again a bro told to let the fishes tahan a bit,do a 20% change.S l o w l y but surely bbs establish again.

Why so slowly(abt 4-5wks).WHY!!! let me tell u why, me again too smart 4 myself hehe.Whenever i top up water i let canister run(guess wat)I point(accidentally of cause) the hose(tap water) at the canister inlet.(ps got put anti-clorine lah)

So the moral of the story is don't point pipe at anyone.wahahahhahaah(fall off chair)

In a nutshell the answer is yes.

But I should make it clear it is not the direct cause. You see, at low concentration (below 50 ppm) nitrate is relatively harmless (compared to ammonia and nitrite). But long term exposure to high concentration will stress the fish out. The fish won't die immediately but it will not be able to develop well. A stunt fish is one where the body is short/small for its age but the eyes and finnage are large for its body size.

For Koi keepers(who want crystal clear water), some reduce nitrate levels by using a protein skimmer and/or plant filtration(water hyacinth,pandan plants).
Not possible to change tons of water daily! Nowadays, can get protein skimmers that work for freshwater as well. These can be custom-made or bought off the shelf. Not sure whether any goldfish lover wants to try it out...

I didn't know we could use protein skimmer to reduce nitrate in fresh water. Are you sure? Hmm.....

There are actually many ways to reduce nitrate. Bro square and I were experimenting on various gadget and setup but I don't think either of us found the ideal solution.

trickle tower by bro square

coiled denitrator by bro cute

canister denitrator by bro sorcerer

For our goldfish tanks/tubs, nothing beats fresh clean water.

Your stock load is definitely too high if your nitrate accumulates at an alarming 30 ppm per day! Do something about it. At this rate, I would have to change all the water on alternate days. If I wait for a week before changing water, the nitrate level would be 210 ppm! That's suicidal!

After reading this thread, I got frighten and I went to Petmart today to buy 2 different brands of Nitrate test kit. I tested all the water where I keep my goldfish. Two tubs in the balcony and one fishtank. The fish tank and one of the tub where I use coral chip in my filter do not seems to register much nitrate reading. However in one of the tub where I do not use coral chip, it shows reading of 150 ppm. This tub has only 5 small ranchu of about 2 inches. My tank in the living room is the standard 2 ft tank with 2 orandas about 6 inches and 5 around 4 inches. I have not change the water in my 2 feet tank for nearly 4 weeks now. I have an ammonia alert which always shows safe. How come no ammonia and Nitrate problem? I use both test kit just to make sure. Both confirm very good. Is my fish OK. Can anyone help me on this??

It's 10ppm higher than I predicted? Goosh!

Tomorrow it will be 110 ppm and it's only day 4 after water change. Siao leow.

1. Yeah... nobody really knows how much plants you need for a volume of water/stock level.
2. It probably will take a while (4 weeks at least) for it to start working.
3. You goldfish might tear them apart.

Hi HB. I have a 3 inches thick coral hip as my undergravel filter that is being operated by a powerhead. The water is being pump to an overhead filter and let to flow back to the tank. I feed my goldfish twice a day with Hikari. I am still very baffle at the reading.

Yesterday I put coral chip in my cannister filter for the tub with poor NO3 reading, and change 20% of the water. Last night when I return home, I did a check again and the NO3 reading was 2.5 ppm.

I have also noticed that the water in my tank turning slightly brown, which I think must be caused by using Hikari. I have still not change the water in my tank. Continue to check it for a little while more.

Has anyone tried using caral chip in their filter?

coral chips have NO effect on Nitrate/Nitrite. The only purpose of coral chips is to buffer the PH levels. Your tank would have suffer a super Low PH/PH crash anytime since 4 weeks with no water change. But u probably prevented it from happening with out 3 inch think coral chips. But most of us seldom use coral chips. instead we use baking soda. you can do a search and read up on this topic. It has been extensively discussed by the brothers here. Part of the Reason being, we change our water frequently and in large percentages.

Your brown water observance is from Hikari pellets. You can try shaking up the pellets in a seperate container with fresh tap water and then tell us if the water turn as brown as your tank water.

Would you mind if you take a photo of your 2 ft tank with 2 orandas about 6 inches and 5 around 4 inches?? I wanna take a look at your undergravel filter.. i presume there is really gravel?? by the way, ammonia alerts are good for a few month in a heavy tank and by then it should be replaced. how old is your ammonia alert? You should have also bought a ammonia test kit to double check your ammonia readings. The low nitrite/nitrate readings could be becaz there is high ammonia and no BB at all.. <-- errr .. sorrie.. brothers here can help me correct this statement if i am wrong hor..
square_guy
at 3" inch, the coral chips bed could possibly serve as a DSB to denitrify provided there is region of low DO in it.

Coral chips are also good habitat for BB.

However, knowing the way goldfish poo, it will be quite extraordinary if the coral chips bed is actually working well enough to keep nitrate at such low level!

best to check NH3/NH4, NO2 and NO3.

There is a product called Bacteria House being used by Koi lovers which claims to be an excellent biofiltration medium

'Bacteria House is made from ceramic and fired in a kiln at 1,300 C. The media is extremely porous which provides ample surface area for bacteria to colonize in. And the far-infrared radiation is very high from bacteria House. Using it in conjunction with the Bakki Shower makes for a excellent bio-filtration system, which requires vert little if any cleaning. All waste is consumed by the bacteria in the filter.'

Check it out at Momotaro Koi website.
I am not sure if anyone in S'pore has tried it out ....
Maybe it might work well for goldfish as well but it is $$$$$!

40 ppm on the 7 days?

depends on feeding rate . if frequent/heavy feeding, easy over 50 on the 6th day.

Why save 20% of the old water? What's in it that's so precious? mad.gif

Let me guess. You want to change 100% but know it's stressful to move the fishes out when you need to empty the tank? If so, find a few small basin and sink them to the bottom of the tank. As the water is being siphoned away, move the fishes inside the basins and make sure they stay inside before the tank is completly emptied. I figured this way you can change 95% of the water. biggrin.gif As you refill the tank with fresh water, the basins will float as the water level rises. Just let them stay afloat for a while to equalize the water temp. When you're happy with the new water... lift the basin and your fishes will swim out.

That's how I do it... sometimes. Usually I just take all the fishes out and soap the emptied tank. smile.gif

G-string prob uses the sponge filters ... and it also depends how u pump the Tap water in. Wrong move can means Killing BB or stressing the fish (if they are left inside) , plus PH flux (some areas have high PH) , or some have IOS etc etc etc etc etc etc etc etc
for me .. if i take the water inside the IOS, it would prob add ups to 10% of wats left. but then again, sounds like he got low Nitrates.. thats why he can confidently leave 20% back on??
