Im going to be getting my paws on a 6ft 220 gallon tank with built in over flows and drilled in the bottom.
I want to set up a sump for this tank and I have the stuff to do it I think
I have a return pump, a sump wet/dry system and a 60 gallon tank to put under it(inside the stand)
I will also have a few 405 fluvals going along with a ac110
What will I need besides help?
Since its drilled on the bottom ,what can i use for substrate?
