I use a CPR 90 HOB overflowbox my tank didn't come reef ready, I have a 20 gallon sump with about 10 gallons of water my dad had an old pond pump laying around so I soaked in and cleaned it out ran saltwater through it and it is able to pump water up my vinyl tubing the 4ft up it needs to but it is maxed out and barely makes it up there id like to get a better pump and run more water through my system but I am clueless to what size pump? It has to pump 4ft from sump to Display tank do I have to change overflows or how does that work?
