Based on your pH and KH your calculation of CO2 at 77 ppm is correct and way too high for fish. You said 3 bubbles a minute, but I think you meant to say 3 bubbles a second. I use approximately 3 bubbles a second in my 80 gallon planted tank. I end up with approximately 20 ppm which is fine for my livestock and plants. Reduce your CO2 injection to get it under 25 ppm is my suggestion. Mike Caleb <cal-@ousd.k12.ca.us>; wrote:Hi Everyone, I need a little help. I acquired a group of eight Bosemani Rainbowfish at the meeting last week and added them to a newly setup 75 gallon tank. They first night they behaved normally (active, curious, all over the tank), but for the last three days they spend ALL their time at the top of the tank day and night. I don't see them gasping for air, but they also show little interest in food. My first fear is that the tank is oxygen deprived. I have a glass cover over most of the tank to protect the lights with a few 2" holes for plumbing and electrical in the back. Could this seal in too much CO2 and not allow O2 gas exchange? I started using an air pump four hours ago, but nothing has changed. However, none of the other fish are exhibiting this behavior (1 large angel, 7 tetras, 12 ottos, SAEs). These other fish appear normal. This is my first group of Rainbows so I'm not familiar with their behavior. Can anyone out there with experience tell me if this is normal? Can't seem to find an answer on the web. All sites indicate that this is an easy species with a wide tolerance for tank conditions. Here's the stats on the tank: One week old, fully planted. CO2 injection (3 bubbles a minute, too much?) East Bay MUD water Schultz Aquatic Soil with sand and some rocks on the surface Lighting = 4x32 watt T8, high output with mylar reflectors pH = 6.5 KH = 8 CO2 = 77 (is this interfering with O2 uptake?) GH = 8 NO3 = 5 ppm NH4 = 0 PO4 = 2.5 ppm (a little high, ODed on the Fleet enemas) Fe = 0.2 ppm Any suggestions? Thanks in advance! Caleb --------------------------------- Do you Yahoo!? Yahoo!
