Dumb question - Wet/Dry Filter

it depends on your style of overflow box. Most need to be primed, but once primed, they will restart on their own. Is yours using u-tubes? an aqualifter?

It has a U tube

U-tubes with no pump attached usually need an assist to get them started. Once started, the water should flow fast enough to push air through the utube to keep a permanent flow going. I used to use an airline thread up into the u-tube and either my lungs or a pump to remove all air from the tube. Make sure to fill the overflow with water... I once had a friend who wondered why no water filled the u-tube when he didnt fill the water up on both sides :lol:

wow! good thing I'm not a brain surgeon, huh? LOL
Thx a bunch

Well... If you were you would pay someone else to worry with it... :thumb:

Man - that'd be nice...
