Cannot seem to find any posts on this issue , the ones I do find do not seem to have a solution.
I am running a waterfarm which has a 4 gallon res with an air stone along with a air lift top fed spraying system.
I let my water stand for 48 hours then adjust pH down to approx 5.5 - 5.7 I then add this to the WF - after a day the pH rises to 6.5 - 7 (no plants in the system, no clay pebbles etc) just a clean system. The bucket I mixed the nutrients in has not changed in pH at all and remains where I left it.
I know a steady pH drift is normal - temps, time of day, plant age , nutrient strength, nutrient uptake , EC etc - I also know pH drift starts to drift slower in later stages when the plant is matured and nutrient levels have increased.
I understand that airstones cause co2 to be removed from the water (probably a more technical term) which then causes a rise in pH. Just curious if anyone figured a way to control this without daily drops of pH down - or is this a common problem with bubblers?
