How do you a tank?

when you clean a fish tank you should only do a 5 or 10% water change. You should wipe any algae off the glass, filter of objects in the tank using a new cloth as any soaps that get in the water will kill the fish. After this the water may be cloudy but the filter should clear this within a few hours. You should never do a 100% water change as this much change will overwhelm the fish and could kill them.
