@ Brian, i have new substrate for 1 thing and ya 2 weeks ago I spent 2 weeks doing water changes every other day due to ammonia spike. I'm just really getting into hobby even though I took a crack at saltwater for awhile and grew up taking care of common FW fish. I rescued a large oscar as well and he is putting a load on tank. He is going to find a new home!! I just cleaned both filters today because I hadn't touched them while I was having water problems (probably for a month). I rinsed sponge good in both filters but did not touch the 2 bags of bio at all. I also did about a 40% water change. Water is kind of cloudy still after @ 4hours but I haven't tested anything yet.
