I had a 26 gallon brackish tank with gravel. About a year ago, I switched to Stony River aquarium sand, which is great stuff. It says it doesn't need to be rinsed but I did anyway. Water got cloudy. I did water changes and it helped but then it would get cloudy again.
I later upgraded to a 36 gallon. I have some mollies and a violet goby. I do over feed a bit because I want to make sure my idiot goby can find enough food. But even when I cut back, it didn't change much.
I use an AquaClear 70 HOB filter with an added bit of batting to filter more. I can't afford one of those UV cleaners. Is there anything else I can do? More biological filter media? More/less light? The light is kept dim at the moment. My Ammonia and Nitrites are 0, and my Nitrates are like 40.
