I ran the same size rez. after a few days of new rez change it would to that but level out. After a week I only ph downed once a week. Water temps should be 68 degrees for best oxy content.
LOC NAR on probation Reviewed by LOC NAR on probation on . pH rising and water cold So.. I have a drip hydro system, and noticed that distilled water you buy from a the grocery store that is just on the ailse and unrefrigorated is still pretty cold. does that mean that in general you need to have some kind of aquarium water warmer in your rez? also, I have a 10 gal rez and the pH goes from 5.5 to 6 overnight, I've seen this question/problem a couple times. Is a larger rez the only way to fix? Rating: 5
