[i'm thinking of just downgrading to an Aqua C Remora Skimmer and just hanging it on the side of the sump Instead of getting a really nice Trigger Skimmer. I'll save about 50 percent versus the Trigger Skimmer, but i don't know if it will work hanging off the side of a sump since the water level is not all the way to the top. I was wonerdering if i can just add silcon hose so that the pump sits on the bottom of the sump? Anyone done this??? I don't want an urchin because i want to save room for the fuge area.]
