I used to use a toms aqualifter for that on my old tank till it broke. Its a really great idea to use your doser for it; I think it'll work great to periodically remove any air at the top of the tube.So I set up one of the doser heads as an automatic primer for the overflow tube. I'll keep a watch on it and see but it looks like it should work.
