Just wanted to pose a question and see what the response here is. I am sure someone else has wondered this same thing so here it goes.
I have a 180g mixed reef (Mostly SPS) with 100g sump/fuge. I have a PCX100 return pump at 1500gph, Reeflo Dart 3600gph running a 4 way Closed Loop, 2 x SEIO 1100 on Controller and 2 x Resun Tunze knockoffs at 500 - 3000 gph on controllers.
Now for the question. With a college basic biology background and as an Active master diver that has dove on quicte a few reefs around the world, I know that during the night the sea calms and that is when the corals do most of their feeding.
I was thinking about lowering the flow at night using timers in a way like shut off SEIOS when the halides go off, the the closed loop when the actinics go off 2 hours later, then SEIOS back on when Actinics come on in the morning, and the closed loop 2 hours later. This would create the clam conditions that are present in the oceans. However would this cause undue stress on the pumps or lengthen their possible lifespan. Would it be beneficial to the corals, would there be an issue of oxygen depletion (should not since return and drains are still running mornally and all support equipment).
So has anyone else tried this, thought about it, or currenly doing it?
