I'm thinking of building a refugium in a planter box above my tank. I just finished my 55 gallon low stand build (21" tall stand + 8" canopy)
Attached is a diagram of my idea, I'm wondering how high a regular powerhead will lift the water. My canopy is 8" tall above the water, so I'd need the powerhead to lift the water maybe 12"? Is that possible or am I looking at a pond pump? Any suggestions as to which powerhead I should get? I'm going to want pretty low flow, since its going through my refugium, but i'm open to actual flow rate suggestions.
