I'm setting up a 150 tank, cichlids. and running a marineland c530
But I have an 80 gallon waiting to be turned into a sump in the next room.

I'm looking to add an overflow box or two, the ones I commonly see on ebay etc, are around 600gph.

That being said, where's the best place to look to buy premade boxes?

Thank You
