Yeah, I just have finish setting up my old aquarium that I left to decay a couple years back. I scrubbed off all the most of the dead algae on the glass; ten filled up the empty tank and used a gravel vacuum to try and get as most as I could of the deposited algae/ dried up slime. Their still a lot of the stuff in the tank and I'm not sure of buying new fish tomorrow because all that crud in the tank is going to decay producing high amount of ammonia. Any thought on this would be greatly appreciated, thanks.
