I have found that all my ph problems went away when I purchased my RO-DI unit...
Also, by using Advanced Nutrients 3-part I get a 5.8 reading after adding G-M-B,
because there Advancede nutes ( they are formulated to be used to grow Medical Marijuana exclusively) are ph balanced to use in distilled/RO water...I then proceed with additives. No problem since using RO water...Is such a joy to add 3-part, get out ph pen, and watch it zero in to 5,8...goodluck
latewood Reviewed by latewood on . PH stabilization in bubblers system Yes, it's very hard to stab the PH in bubblers system or in any system where water is aerated by air stones. I notice that i start a rez with PH 6 and the day after it's 7 so i've got to lower it, and under some particular conditions, the PH is 4!!! Now i've got the exponation from an aquarium seller. When there is few CO2 in the air, there is more oxygen, the PH goes up. When there is a lot of CO2 in the air, less oxygen, the PH goes down. When i saw py PH to 4, i had added CO2 the day before Rating: 5
