Ok so I'm testing before I get started, I fixed the ph and bulged everything up. I wake up today go to work and come back to find the water in the res kind of grey and not clear like it was last night, I cheaked the ph again and it read 6.6 it went up from 5.6 last night to 6.6 today and the water in the res is no longer clear it's kind of grayish. The res was covered and the room is spotless I have an air pump in the res mayb.e that did it. My question is this why did the water transform over night and why did the ph go up like that, I do not want this to happen when I start it up for real then my babies die. Any advice or comments regarding this issue is greatly appreciated. Thx!
