Hi guys, sorry to ask this noob question. I know that for co2 drop checker.. Blue color mean low co2 level, green is just nice and yellow is too much...
And I knw it's take a few hours for to co2 drop checker to show change in color,,,
But I still very puzzled.. Should the co2 dropchecker show green throughout the 8 hrs when I on my co2 and light, or shOuld it's change to yellow at the end of the 8hrs... Can someone please enlighten me this blur sotong and advise me if i'm wrong.

My current set up is on co2 and light together , 9am to 5pm.. 8hrs..
Morn, co2 dropchecker show blue.. By 4pm, it's dark green in colour.. Is this correct? I currently on 1bps

hi

For mine, i always had it at light green throughout my lighting period and by time i switch on again the next day, it is green - dark green. However, i do had slight algea issue so i tried changing it to be light green throughout my lighting period and by end of lighting period it is yellow and by time i switch on again, it is green, and my algae issue improved significantly since most of the algae issue is directly related to insufficient CO2.

Maybe u can try increasing ur bps to 2, depending on ur plants too, if is mosses which require lesser co2 den it shouldnt be an issue so long no algae issue

just my 2 cents thought, i am still quite new to planted tank too
