ph levels

[kevh44]

how do i control the ph levels in my nutrient solution it constanly rise's every 24 hours even though it has been balanced previously im useing clay pebbles and a wilma system. advice would be greatly appreciated

I have no experience whatsoever with the wilma system. I can only attempt to help you out by saying this : If the pH is too high, adding a solution with nitric or phosphoric acid (pH down) will lower it. If the pH is too low, a solution with potassium hydroxide (pH up) will raise it.

You did Gooster. Same question was asked in another thread. You are still sane.
