I just added a reef dose 2 to my system to help a little with the alkalinity and the nitrates. I was just curious on if I need to somehow vent the bottles. It seems like they would slowly go into vacuum as the pumps start pulling fluid out. Anyone using this system that can let me know what I need to do if anything.
