Im currently using 2 return pumps and 2 power heads for flow in the tank. I like the redundancy that having pairs provides, but now that I’ve switched the goal of the tank from sps/mixed to LPS/mixed I would like to lower the flow in the tank.
I’ve lowered the settings for the power heads but I think I need to decrease the return pumps as well. So far Ive adjusted the pump intakes to restrict water flow, but it is still providing a lot of constant flow.
I am considering using the original Y plumbing and returning to a single return pump, but then I have concerns about the pump failing. Last night I lost power and one of the pumps didn’t turn on when the power came back. Easy enough to fix when I’m home, but I travel and it would not be good if the tank was alone for a few days.
I think I may need to get 2 smaller pumps, but I also have a somewhat crazy idea of splitting the output and having some of the return pump flow coming out in the return chamber to prevent detritus from settling back there. I would still have a slow flow area with my ceramic media in another chamber and I think that getting the detritus in the water column will make it easier to remove with mechanical filtration.
Any thoughts? I have a T that I could put in one of the lines to see how it performs, but I’m also open to other ideas
And returning to something besides return pumps… the tank is looking nice! Water has been clearing up and I have pretty decent viewing distance down the 3’ side. I am seeing a lot of pods on the glass and think that the population may have declined while in the smaller temporary tank and that may have been part of the film algae problem. Now that the population seems to be increasing the glass only needs to be cleaned about once a day vs the thick film after an hour…
Here are some pics
This toadstool never extends cause my coral beauty likes to eat its “polyps” like spaghetti. I probably need to rehome it but it’s my first coral and I grew it from a small frag. I’m trying to feed the CB more and hopefully it’ll stop snacking.
Side view is getting pretty clear!
