So are you saying then that I would only need it if I didn't have enough surface agitation, or I had a surface scum buildup on the top of the tank? I think I am going to still hook it up though because in one of my past DIY projects I cut of the bottom of the HOB filter intake tube, so right now it is just a tube with not strainer on it. Inorder to stop it from sucking up things such as fry, I will put the skimmer on. Can't hurt right?! Anyways I will post picks soon, once the water clears up. I think I might put some crypts into the tank too, as I think right now it is a little lacking, do you think they will grow in water above 8 ph?
