drop checker solution????

best price is probably on ebay.

you need 2 solutions. fill your check ~half way so it has the most surface area with your 4dkh then add a couple drops of your regent.

process... turn on co2 slowly... give it a couple hours... check color in drop checker... turn up co2... couple hours... check color... repeat till it's green...

to fill and clean it you'll have to take it out of the aquarium.

+1 :dance2:
