Re:Koralia powerheads?

I have a Koralia that works great in my anemone tank(no seahorses). Just in case I bought a piece of Tulle(bridal veil material)to cover it. I got the purple tulle that looks just like coraline algae. Just cut it into a square and put it over the Koralia and secure the ends with a zip tie. Think of it like a lollipop wrapper-if the pump is the lollipop the tulle is the wrapper and instead of twisting the paper at the bottom like a lollipop you secure with a zip-tie. I have H. fuscus and H.barbouri and they could definetly hitch on the Koralia(and I have the nano) The pump still works great and nothing can get in it.:) 🙂
