i had one question. i got a glass tank and hang on overflow, is there anyway to use this overflow with filling up the tank all the way up? i generally like to keep about 1 inch of space btw waterlevel and top glass.
shoefreak03 - is the hang on overflow adjustable? the skimmer part that is inside the tank? If you can adjust it so water is flowing into the skimmer box then yes it should work.
