water quality

I've had this 65 gallon aquarium for over a year and haven't been able to keep any fish alive for more than 2weeks except for my striped Raphael Catfish and mystery snail. Water temp is at 79, pH is 7.7, nitrates around 20, nitrites 0, KH 40, GH 60 and ammonia between 0 and 0.25. I have one...

Do Bichir prefer soft, medium or hard water with what ideal PH? I was thinking 3-6Kh with a Ph around 7-7.5? But all comments appreciated.

He guys so about a month and a half ago I set up a 55 gallon tank for a good friend of mine. I had a high budget so I decided I was going to make it a super nice tank. His only suggestion was that he wanted sand. Everything else was up to me. So I got some stone hinge and a nice Fluval FX4...

I usually do two 7.5 percent water changes a day, once every twelve hours or so. I change out about 30 gallons of water a day. By doing this, I can keep my nitrates at 5 - 15ppm, but the hardness is very low, at 0 - 0.25ppm. Any suggestions on how to keep it a little higher without cutting down...

Hey everyone. I'm wanting to know what you guys are doing when changing large volumes of water when the water from the tap is very bad like it is in Phoenix. What I've been doing is filling a 55 gallon plastic trash can, treating the water and then transferring the water to the tank after...

Good afternoon everyone, TLDR; Woke up after moving my arowana to find two of them had cloudy eye that I can't seem to beat. I've tried nearly all the remedies I can think of and looking for more suggestions. Long time lurker, first time poster. I recently got back into Arow's after about a 5...
