I calculated that my co2 level is 39 but the recommended level is 25? I'm sorry, i'm terribly confused about this. The ph level is 7 and kh is 13, so it would make the level 39, right? And it should be 25? The only thing that i could think of that what could have caused this are the fertilizers

I don't use CO2, lights are 2x30W and they are on ca 7h in the day, but i have turned them off in intervals because my lethargic fish became more active when the lights were off. I now stopped using the fertilizer, but it was bennerle s2 vitamix and v30 complete pluss, sometimes i used JBL...

How could i reduce CO2 levels in my tank? Could the high levels come from fertilizers? I have now stopped using them, but my fish is lethargic and the ph has come down and CO2 has gone up (O2 level seems to be fine though). How could i fix this?
