Hi @Harlan Ford, Jude here, I just stumbled across your channel! It's awesome to see you are still keeping fish. I still remember when you gave me a hand breeding bristle-noses for the first time!
Wave makers have been rumored to keep tanks cleaner by keeping particles in suspension and that way it can find it's way to the overflow, personally I haven't tried it in my tanks, but who knows maybe it works😂
