i have all my stuff drain into a 45 gallon gar. pail then i devert that water to a skimmer (pump) ,refugia (2-45gallonplastictanks),The 45 gallon gar. pail also feeds the 2 refugia, witch drain into the Vat100g(no skim or filtraion st, tru.). The skimmer clean water goes to the Vat, along with all my other stuff., the 2 heatrers, bioballs to knock out bubbles, calicum reactor input, Kalk in here, ground probe, fresh water make up all day off my Automatic RO sytem.
Extra over flo goes to a 100black vat.
the 2 20 gallon tanks are pumped off the hammer head, drain into the 45gallon garbage pail
the hammer head is mounted to the vat, on oppsite end of all the other sy=tuff, and feeds back up stairs too, maybe 25 feet total...
the vat is where all my water goes if the power is interupted (3 tanks and all head pressure from the pipes...(alot of water so make it More then u need

))
