surface skimmer help
I've been trying to make a surface skimmer for my 55g...My origional thought was to use one of those little critter keepers, drill holes for suction cups, use the grate style lid to keep out large debris, and feed my canister filter hose through a larger hole drilled in the lid. (Sorry no camera to take pics)
My down fall with this is the suction cups allow for some movement vertically, so when the level of water drops in the box it starts to float reducing the intake causing the box to float more and more until ,GARGLE, everything goes sour.
My next idea is to cut some slots in some pvc pipe, possibly attach with the same suction cups.
Has any one done this...make their own in tank overflow...with success at balancing the flow so the surface scum is pulled through the filter??
