Hi
I was just wondering why CO2 could be present in my tank in tank after many hours with no injection.
CO2 was shut off at 21.00(9.pm) and now at 8.00(8.am) there is still a decent amount present.
I have a powerhead creating good surface movement and a surface skimmer running 24/7.
I'm currently been measuring ph at intervals using drop tests (find out my ph probe was faulty), and ph drops very slowly over night.
This is ph test this morning.
after lots of shaking / blowing air into same vial.
.
Anyone have ideas on why so much CO2 is still present, or could it be something else?
