Hey guys! I am selling a glass co2
drop checker, and 4 dKH
solution for the drop checker.
The glass diffuser is in great condition the ceramic disk has a slight stain on it from the tank but is clean and works very well.
drop checker is in great condition but is missing the back suction cup.
The 4dKH solution is magical. Put some in the drop check along with 3-5 drops of ph test solution from your test kit. It it's blue there is not enough co2
in your water, green is just the right amount of co2
and yellow is too much co2
in your water. There is only half a bottle left but it lasts forever!
I am selling all of this for $20 plus shipping. Enjoy!
