I am new to the boards so please excuse me if this is a repeated question.
Anyways, I am looking to purchase a skimmer
and would like a recommendation. I was debating to look on Ebay for a used one but should I just purchase a new one? Also I don't understand the differences between a HOB
and a Sump?
My tank is a 75g reef tank with some reef fish. I am using a trickle down filter or wet/dry filter system under the tank. I have some room behind the tank and some room under the tank in the cabinet. Any suggestions would be appreciated.
