Hi all,
need some advise, not sure I am in the right forum. I got myself a DP-6 dosing pump from ATI. In theory it is all good if somewhat noisy but I get over that.
My issue is with the fact that the tube sucks in air where I have it and the bubbles rise in the tube and basically prevent future dosing that just keeps pushing the air around. I tried by cutting the end of the tube differently, putting the pump itself above the outlet (I don't have a sump so now the pump is on top of a shelf with tubes hanging between the tank and the shelfing unit. Today I thought I try to add one of these auto drip nozzles from the watering system for the garden at the tip as I thought it might help if the outlet is smaller.
None of these hacks seemed to help. Still, as soon as I have removed all the air from the tube, the liquid (alkalinity from 3 part dosing) starts dripping out of the tube and the bubbles rise (about 3 inches in). So the pump is just pushing air around for the next few dosings and I don't really have small dosages. I would highly appreciate any ideas that could help me.
