Is my drop checker showing adequate levels of CO2?

[laurenb252]

Hi all,

I’ve recently set up a high energy 115L tank which has had CO2 running for just under a week now.

I’ve got a drop checker in the tank but I’m not exactly sure how green it has to be in order to indicate good levels of CO2. I’ve attached what it reads at the moment, is this what I should be aiming for? The bubble rate is currently set at 3-4 bubbles a second.

Thanks!

Dark Green = good level of co2, fine for most plants.
Lime Green = high level of co2, pushing the limits but still safe.
Yellow = danger, stop immediately!
Blue = very low co2

Yours looks dark green to me

I find your water hardness effects how easily the co2 is dissolved into the water.
Hard water is a lot harder to dissolve co2 into but seems to fluxuate less..
I don't know if anyone else has found similar, have to be careful when adding Ro water

Ps I agree with little on the colours, yellow is frantic water changes and fish practicing floating on there backs.
