hi all , been using for the last few months a pressurized system . my tap water pH is : 8,4 I use ADA ph test, bromo blue I think, which indicates blue near 8ph and green near 7 ph. I run it on a timer (starts one hour before the light comes on, stops one hour before it goes off) 1- my drop checker (thing that needs time to react ) stays greenish 24/24 2- last time I tried to aerate by night the water (with my boyu) This is my pump, and I simply use the air tube that makes air bubbles on the output of the filter then the morning i noticed that the DC color was blue . so that indicates that i have fully degaze off the co2 , and that means that this was never done before i kwon that ada company use pipe to aerate the water by night . i know that i have to approach 1ph drop . to make co2 available in a correct amount . should i do this every night with a timer on the pump to totally degazz off the co2 by night ?
