:?
I need help managing a host of strange occurrences in my new 55 gallon tank. Its 4 weeks old and has sustained its 4 plants and 5 zebra danios from the start. Plants growing about 1 inch per week and fish disease free i think. I have done 1 20% water change and test the water each week. Ammonia and nitrites are low. pH keeps rising to 8 and water hardness is about 8-10. More algae growth than expected on rocks and tank walls ( reddish brown and green in color). Big problem: at night fish seem to hover at top in need of air. To fix problem I have raised water output each night to make water splash but fish still seem to be less active and hang at top more. When I had heater problems I realized that this only occurs when tank is above 71 dregess. At lower water temp fish seem more happy and more active. I am also trying to attack the pH problem. Have added neutral regulator 1 time each week for 2 weeks to adjust pH with no success. pH of tap is around 7, all rocks purchsed at fish store. Plant substrate the culprit??? Please help!
