C02 Higher In The Morning?
Hi everyone, as you can see I am still trying to fine tune my c02 injection. Degassed tank water is 7.29 and I'm shooting for a 1.2ph drop by the time the lights come on at 3:30pm, that should put me at a ph of 6.09 So the c02 comes on at 12 noon and the ph is at 7.08, by 3:30pm (lights on) the ph is 6.25 and basically stays there until lights out at 10:30pm. The c02 shuts off at 9:30pm one hour before lights out. I got up this morning at 8:30 am and my ph was 6.10, what I want but wrong time of day lol. I have good surface agitation via powerhead and cannister return and Seneye monitor estimates 02 at 8.4. Fish look fine, no gasping at surface so I know the 02 is good. Should I still shoot for my target when lights come on, at the risk of overshooting it by early morning? 02 suggests that I dont need an overnight bubbler. Am I right in assuming this is left over c02?
Thoughts and comments always appreciated!
