Hello everyone, I thought I'd ask for your advice and recommendations on drop checkers. I thought it would be useful for my planted 25 litre nano, as I aim for a constant 30ppm of CO2.
I really want something cheap and efficient so have been searching E-bay, but as I don't have much experience with drop checkers I'm not sure whether they're good or not.
Heres the link. Are any of them suitable? Is it pointless me having a drop checker?
Cheers,
Mike
