Aliens In My Tank

[Angry_Platy]

Since adding pressurised CO2 last week (5 days ago now) weird things have been happening in my tank. To make sure I have the flow rate right I have been testing pH and KH daily to make sure I am not overdosing with CO2. WELL.....my pH and KH have been different every day I test.....like Saturday my pH was 7.1, Sunday it was 6.9, Monday it was 6.7 and today it is 6.9 again. I am testing at the same time every day. The flow rate of my CO2 is the same everyday.

Is it normal to get these variations when you start using pressurised....like is my tank just getting used to a constant steady suppy of CO2?

I don't get it.

re test today and i think you'll find it's 6.7.

the co2 will gradually drop the ph so everything apart from today makes sence. it should stop at a point and then stay constant. this has only been running a few days has it not?
