I have a 15x15x7 work tank that I just noticed has a slight leak in the front bottom left corner. The leak is very very slow but it's a leak non-the-less. Question is, if I remove all the water, rock and corals, put them in a separate holding tank, remove all the current sand, fix the leak/reseal the entire tank, and use NEW sand when putting everything back in, will I have an issue? Thanks guys, Joe
