Ok, I am no fluid dynamics engineer, so I am totally confused about what to do for returns from the 1" PVC coming out of my overflow.
I have a 1-1/2" drain line with just a couple 90s....manufacturer says its rated for 1600 gph max. I have 1" return PVC with a Pan World Pump rated for 2000 gph. I have about 4 90s and 2 45s, a couple true union valves, and about 6' of static height. I also have a T off the return, feeding a small amount of water to the refugium...valve is only open about 10%.
So my question is what should I do on the end of the 1" return PVC at the overflow? I also have 2 Vortec MP40 pumps at one end of my 52" long tank....running both as masters in reef crest mode. I cannot put one of them at the opposite end because of clearance issues.
Should I use loc-line? If so, would you T off and go to each side of the tank, and how big of Loc-Line, and how many nozzles? I do not want to restric overall flow, but I have done some reading and it sounds like reducing flow can increase water velocity, which would be ok?
Thanks for your help!
