in the process of mapping out a 475 DT that's currently being built by Derek at Miracles set up for a closed loop system. Haven't landed on where i should source a sump yet (open to any suggestions here) but I'd guess the sump will be around 100 gallons (60x24x18). Here's my dilemma...
with approximately 13' of drop from the display down to the sump (sump and EVERYTHING is in a room on the floor below) I have to have a pretty decent sized pump to push the water back up that high after it's run through the sump. I understand I should try to run about 5-7x flow through the sump so if i base it on just the DT alone that's about 3000 gallons / hour. If I spring for the Red Dragon 3 speedy 230 high pressure model and run it at 200w so it's not wide open literally 24 hours a day (I'm assuming I shouldn't run it wide open all the time) it looks like given the head pressure to push the water back up to the DT I'll still only achieve 1900 gallons an hour. That only gives me 4x DT volume for sump flow. Is this OK? Is there another set it and forget it "Mercedes" pump i should consider? I didn't realize how much more difficult and expensive it was going to make this build to put the sump and "equipment room" on the floor below the tank.
I had intended to even mount the closed loop pumps in the room below and just plumb to them in an effort to keep the noise and all the equipment in the same area but given the head pressure challenges I may opt to at least mount the closed loop pumps directly under the tank. I figured for the closed loop (2 intakes and 6 supplys) I would run two red dragon 230's not the high pressure version and each would provide about 6000 gallons an hour in flow.
What do you guys think?!? Is there another brand of pump I should look at?
