Take the pump out, its not really helping. Also a pump in the res gets warm and can breed harmful bacteria, a grower on afn has already run into that problem. Air in the rootzone is a different thing and works fine.
I apologize should have been more detailed, I started off with a actual pump in the Rez that went out got another pump but this one uses tubes in the Rez instead of a actual pump on my 2nd round with Remo and the auto pots going to monitor the ph more closely dial things in so too speak I never used a res before so a newb to it I appreciate the responses guys

praise the Gospels of Factual reality on this Joel!
, at the Infirmary especially,... soil/soilless growers in particular seem to equate this with actual in-pot pH buffering and management, and I tell them that it just doesn't work like this once in there, only when in solution! Too many other influencing factors, and the capacity of the solution buffering is too weak to deal with it all,.. there is no set-it-and-forget-it with pH in these circumstances,... Something I wish the manufacturers would actually state clearly in the instructions-
But you know how it goes, some get away with it by sheer dumb luck, and then they think that's the norm'!
