Green Water: Yes
Country: Indonesia


I have two fiber tubs that hosting my 20 ranchu and orandas, tubs positioned on top of my house. This is covered by direct sunlight all day long. Tubs was setup like 1 months ago, I was wondering if sunlight is too much for my fishes?

water in the tub is so green i cant even see my fishes , I have read about cultivating greenwater in this forum, tubs water gone green after 3-4 days after tub setup. Did not do much, dunno if this is the precise technique that we called greenwater. every 2-3 days Im doing water change in the morning around 30% then water became clearer at least the fishes are visible but later on in the afternoon became so green that make fishes not visible. Is this normal?

To much algae will cause " Oxygen Burn" ( air bubbles in the fins) I've got the indoor aquarium rutine down...I am trying the original technique of using green water outdoors now, a completly different science....I was a little (very) upset when I put my really nice Calico Fantail, Panda Telescope, & Ryukin in the green water that I started with my Ryukin (about a week to turn true green) and after two weeks total...my fish's fins would develope bubbles in their fins...after only about an hour or so of being in the green water. Problem, green water to strong ( to much algae = to much oxygen= Oxygen Burn). I am well aware of weekly 25 % water changes in my indoor aquarium to remove excess amonia. However, "Green water" is different; you don't remove excess amonia...you remove excess algae which produces excess Oxygen which will cause "Oxygen Burn." As I was reading in this forum, It said to keep 10% green water, change 90 % into new clear water (dechloranated of course) and put the 10% green water back in....Every Week! I'm going to try this later today as I had to save my babies.... aikido.gif
