no, it's not a Country song - my kids won 3 goldfish at a carnival and, like a good dad, we went and got them a tank. $70 later, those free fish are starting to look pretty tasty. But I digress... I went to Petco and got a 10 gallon tank, 2 bags of gravel, some plastic plants, an aqueon quietflow 10 filter and Spongebob house. Cleaned it all, filled with well water, added some Aqueon water conditioner. They've been doing just fine for like 2 weeks now - yay me... I looked at the filter the other day and it was disgusting. I drained the tank, rinsed the gravel, washed the tank, refilled with well water and put in a new filter. 2 days later, the filter is already brown. is that normal? I know goldfish poop alot, but I just would like to know if the cycle will level out and I won;t have to put in a new filter every couple of days. Any other suggestions?
