Okay so i recently moved my 46g tank after almost everything died off. I did a 50% with the move and cleaned the tank and put new sand in. I have lots of detruis already from off the LR. The only thing left living on from my tank was a 1 eyed clownfish. So what im asking is, What should a cleaning crew consist of in a 46g tank. Mainly to keep algea and detruis down.
