I just bought a used acrylic tank with lots of crap, but don't have any idea what how all the stuff fits together. It was saltwater and I want to turn it into a hillstream freshwater. I don't know alot about saltwater tanks, but it has a hole drilled in the back, middle, bottom of the tank. I'm assuming that is for an overflow setup (its not there), just the hole.
It came with an overflow/sump/wet/dry acrylic filter box. It has an emblem "Nova max" on the box. It has 3 holes on the sides with connectors.
So, the upshot is that I have a 55 gallon acrylic with a hole drilled in the bottom. I'd like to use the sump/wet dry filter and possibly as a fry collector (seeing as Emma has been so successful

So I'm looking for ideas
