ph level dropping - What can be causing it to drop?
Hello, My PH level is dropping from 6.0 to 5.2 in twelve hours. I'm running a 150 gallon res feeding 360 heads of lettuce in the flood table. The monitoring system is mixing nutrients ok/holding temp ok/ but will only lower ph if above 6.2 and not raise it if it's to low. I do have a small algae build up in the res.Could this be a factor?
