[Sherman]

I running a Korallin C1502 Calcium Reactor since my 5 footer setup about 3 years ago.

Saw the diagram insert with C02 connected back to the in feed line.
Go back to my tank and see my own Calcium reactor for a few moments .
Finally decide to to reconnect my purge line back to the infeed and see if I can recirculate
my excess CO2 this way. That is 21st Jul
Today 23th Jul check my display PH record before going to work.
