Hello,
I am setting up a new 125 gallon Oceanic tank and was wondering if my LFS sold me the right pump, a Dolphin 900.
It didn't come with a head pressure/ gpm graph, and the web site doesn't show one for this model. It states max flow as 900 gph, 17 ft max (pressure?).
I am plumbing 1 " pvc spa flex and rigid pipe combo, tee'd for discharge back into tank corners (2 lines). Something like 9 ft horizontal pipe with one elbow to get me out of the cabinet and three elbows to get me back into the tank at each corner. I put two 1/2" outlets on each corner discharge (vertically stacked, one about 3" lower than the other). I thought this might help create some flow patterns in such a long tank (6ft).
My husband is begging me to put in two more elbows, to clean up the look of the back of the tank where the hoses leave the tee and arc up to the discharge. I admit that would look and sit better but am worried that this would be problematic with the pump. He thinks I am overanalyzing things, but I am a scientist by trade and I can't help it. Could I do this without trouble? Could I do this with a larger pump? Do I need a larger pump anyway?
Other facts: 20 gallon tall glass aquarium for sump, 2 tidepool SOS overflows ('up to 600 gph each') with 1-1/4" drain hoses, 30 gallon refugium feed by tee off of one drain hose with gravity drain to sump via bulkheads, turbofloter 1000 skimmer
I know you guys have better things to do than analyze my situation, but I need HELP! I already have a $550 store credit at the lfs from all of the wrong stuff that they sold me so far, I want some better advice than what I get there.
PS. I plumbed a tee with a ball valve straight off of the pump return line to direct water back into the sump if necessary (3/4" valve/ pipe). I don't know if I need that but I read about that here and thought better safe than sorry.
Thank you, Thank you, Thank you, for all and any input!!
