Hey everyone. I have a quick question about my bubbleponics set up.. I started the pH in my reservoir at 5.5. It moves up during the day to around 7.5. I switch a gallon of 7.5 water out with 5.5 but by the end of every day its back up to 7.5 or higher! Please help. This is not where I want my pH to be and I need some assistance. Can someone please tell me how to keep my 6 gallons of hydro water to stay at pH 5.8-6.0 without having to adjust it twice a day?
