Ok, I can put it in the middle top of the tank, I have like a platue thing there. Thing is, above that is where the skimmer drops the water back in, its a diffuser box on the coralife super skimmer so if you know what I mean, maybe a few inches above where the acro would be. Is this going to hurt the acro if the skimmer dumps water above it? Skimmers aren't like powerheads right so it wouldn't really bother it or would it hurt it?
