Do you have an issue with back siphoning? I have a T on the 1.5" return inside the tank with a pipe above waterlevel. I think I'll only be able to get a 4" filter sock on there but that's on order so I need to wait.
I was able to get the skimmer under control with the drawstring filter bag. I'm using 100 micron since that's all the LFS had... hopefully it won't dirty up too quickly. FINALLY I'M SKIMMING!
