Nope So far no problemsGotcha. Any issues with them falling off on your 120?
Yeah, I'm basic with mine too. Always had jebao and have worked well for meI have the 20 and it seems fine. I went with the 20 because I heard that the 30 rattles and makes a bit more noise...
Im not a connoisseur of powerheads though....I've got a bunch of cheap sunsuns, the slw20 and the scp180 all in various tanks
How much more beneficial is a wavemake over a simple powerhead like the hydor? Is it the water movement in different directions? Ive always had fo tanks til I set this biocube 32 reef up.
