Thanks in advance for any input!
I want to build a ’loop return’ for an ELOS 200XL. Because I want it to run very quietly, I’ll be keeping the total GPH to ~3000-4000/11k-15kLPH. My plan is to have relatively high pressure but smaller ‘main’ lines (3/4“/20mm, matches the return holes drilled in the system) coming out of an Oceans Motions 4-way. Then, I was thinking I’d use 1/2” exit T’s with eductors, probably 8 of them. My goal is to move more water with the eductors, and make sure I’m supplying enough pressure so that they’re effective. (Open to suggestions here, I’m definitely not an expert on plumbing).
Which brings me to...
A pair of pumps (redundancy!) that can maintain a relatively high pressure but relatively low GPH/LPH (as listed above) and be virtually silent about it. I like the Reef Octopus VarioS pumps in another system I have, but they state that they’re not designed for constant pressure applications. I’m not sure how much pressure constitutes a “pressure” application, but there will be a relatively decent amount of pressure flowing through. The actual head height will be relatively low (~100-150cm, ~3-5ft) but there will be pressure from all the Oceans Motions 4way, all the plumbing, and the fact that every return is going through a narrower outlet with an eductor. I’m not sure yet if I’ll dry or wet mount them, but I do want controllable pumps, and quality/reliability/quiet operation. Thoughts on either a pair of VarioS 8’s or a pair of Abyzz A200’s? Any other suggestions? Money is no object, but I care very much about quality/reliability/quiet operation, and hopefully very little maintenence. I’d way rather pay a premium for something I can rely on without having to replace seals, etc on a regular basis.
Btw, it doesn’t have to be silent, but definitely quiet (~25db or less). I’ll be lining the interior of the stand and back of the tank with sound reducing material, in an attempt at silent operation.
Thank you!
