I have a Red Sea Reefwave. I've been getting some cyano on the sand and I've read that it could be due to low flow along the sand bed. I tried moving my Reefwave down but it seems to cause too much flow to my established corals.
I was thinking about getting a small powerhead to place just above the sand bed but I don't want/need it be be really powerful.
Anyone have recommendations of a small/weak powerhead that would fit the desired application? Or am I just silly to trying to do something like this?
