Any advice on how to safely start a new tank using everything from the old tank. I was thinking that if I just move everything over to a 5 gallon tank all the nasty stuff in the gravel, that that hasn't been vacced up, will cloud the water and cause a spike in ammonia? I would add 2.5 gallons of new water too but still. Probably 5 more pounds of gravel as well and eventually more live plants.
