I do every 2 weeks but I will..I just did yesterday....is 6- to 10 drops of pH down to much for every water? I know I was going to heavy on solution before I thought it was safe to use and sometimes I would use to much down and have to use the up to get it in range....I know that the solution is blue, but just for shits and giggles can you calibrate that PH pen just for the hell of it?
