Hello, My husband has a 5 gallon betta tank, with one betta. For over a month, my husband cannot get water clear. Water is green all the time even after water changes. Before he came home from work yesterday, I tested parameters API. pH was 6.6 - 6.8, no ammonia, no nitrite, and looked to me like nitrates were between 40-80. He did a 50% water change. He told me that he had previously been doing about 75% water changes. I told him no no no?? He never checks parameters, for whatever reason. Would adding a little African Cichlid Mix help raise her pH to 7 or is it necessary He has several large tanks that never have an issues, and this betta fish is thriving as far as I can tell. However, I feel bad for her because her water is always green. I have considered all possible potential causes - the HOB filtration, the plant (Aponogeton Ulvaceus Bulb), the heat from the bulb light in the lid, the decorations and the gravel substrate. Her tank stays around 79-80 temperature. Hoping to help, I put an air stone in her tank last week, does she need that? The air stone seems to cause a lot of surface agitation. I wonder if we should begin a new tank for her, with an old sponge filter that is in a different tank already? Although the betta is well, how long can she live in that horrible water like this?
Thanks for ideas,
