Please advise the optimun duration my CO2 should be on?
At present it is switched on and off with the lighting timer = Six hours per day.
Is there a benefit in having the CO2 on before lights on and off after lights off?

Also, I have read conflicting information regarding drop checker reagents.
My tap water KH is 2 will a drop checker filled with 4DKH water and reagent give me an
accurate reading in the tank?

Kindest Regards: Peter
