Hello everyone, I recently setup a 75 gallon tank that I purchased from Craigslist. It came with a purple dottyback, a brittle star, and basically everything I needed to get started exept a skimmer. Is it OK if I don't have a skimmer running on this tank for a few weeks since it has such a small bioload? It has a sump/refugium and about 60 lbs of live rock in there too.
