Hi all, I'm just wondering if anyone else is running into the same issue as me with the AN pH perfect line. I'm doing a dry run, testing a new Wilma and basically the pH just is not adjusting to the levels I'd like; from a base of 7.3 (~200ppm) the pH has stayed pretty stable at 6.3. My base water is perfectly acceptable according to AN. I'd be happy running that with soil but not in the Wilma.
I've made two batches, one at 2ml/l(~750 ppm) and another at 4ml/l(~1600 ppm) both stay at 6.3. I'm not one for AN bashing, they've always worked well for me in the past. I've popped an email to their tech support but thought I'd bounce it off RIU.
The only thing I'm thinking now is the water temperature, currently at 16C but I've stuck an aquarium heater under there to see if that makes a difference. Anyone else have similar issues?
On a side note, I spoke to the guy in the hydro shop earlier who told me I would still have to adjust the water to whatever medium I'm using. That isn't my understanding of the pH perfect line but I'd be happy for someone to correct me or him!
