My big tank has a water-filter ,it hold enough I don't have any problems with it, Its the little 10gal pull-around, that spray water some-times, I have 1 at the outlet & a in-line at the end of the hose, and still spits. I know! its kind of like telling the docter "it only hurts when I do this" . But, I was just wondering if someone had a idea how to fix it?
