Ok this is weird... I have a 30 gallon tank that's not completely cycled yet and is cloudy as hell. You can't even see the heater on the backside of it. Anyways, I tested ammonia and am at 0, so I assume it's the nitrite bacteria building up. I would verify this, but there aren't any petshops around here that have nitrite test kits and I'm dirt poor, so it'll be a while before I can order one online. I came home today and noticed what looked like water spots on the inside of the tank. I looked closer and they MOVE! I'm kinda freaked out and have never seen this before, even though I've cycled a ton of tanks. Oh yeah, and I might add that I put a chemical in there. First some Ammo Lock 2 to make sure all the chlorine was gone, and then I waited 5 minutes and put in some Zyme #7, made by a company called Fritz. It's supposed to be better than Bio-Spira (and this came from a Bio-Spira dealer). Anyways, anyone else know what the hell may be going on in the tank with the "living water spots"?
