hi
i have just finished doing hypo on my 30g tank which now has only 1 fish left in it that has now been free of ich for about a month

. i am going to be transfering this fish(firefish) to another tank and getting a fuzzy dwarf lion. I was thinking of maybe leaving the tank empty for a few weeks before introducing the fuzzy dwarf just to make sure the ich is definatly gone.would leaving the tank empty do it any harm or cause any problems to the water quality or is there anything i need to do to it while it is empty.
any advice on this is very much appreciated.
thanks in advance

Leaving the tank empty won't hurt it at all. You might want to add a small pinch of fish food every week to feed the bacteria though.
