I have a 55 gal. that I am going to run through another tanks wet/dry. The problem I have, is it doesnt have a corner overflow. I have a hang-on overflow that I picked up a few years back. Its the type with 2 conainers one inside your tank and one one the back with a j-tube conecting them. I cant figuire out how to get the siphen going? Ive tried everything. The lady at the petstore told me to put an air-line tube through it and suck. Ive tried this and with larger hoses with no success. Can anyone help me get this overflow to work???????????
