About this product
A drop checker gives a slow, visual color-shift read on dissolved CO2 in the tank itself — green means your injection rate is in the safe, effective range, not just a bubble count guess.
Useful for any planted-tank keeper running pressurized or DIY CO2 who wants a passive daily confirmation rather than relying on bubble-per-second counting alone.
In the box: the glass drop checker and its suction mount — 4dKH indicator fluid is sold separately and needs periodic topping up.
We source this to order from our supplier network — sourced to order, ships in 30 days — so it arrives to spec, not off a dusty shelf.
