If you reccomend to add Acid to lower the PH and in turn the ALK at the same time - can I add the Acid the same time the CYA sock is hanging?
Do I leave the filter running during the add of Acid?
How long after the Acid is added to I retest?
I assume the Acid will lower the FC and CYA (assume) as well, if so, how long after adding to I add more bleach and or CYA?
Any advice on Acid is wonderful!
