I am adding a calcium reactor to my system and bought a Korallin reactor but it didn't have a PH Probe Port, So I Googled to see what a new lid with ph probe port would cost and I found a new lid for $65. As we all know how expensive this hobby is so I decided to see if I could add one myself. First I found a Ph Probe adaptor online for $8, I had the Drill bit ( 45/64 ) and a Tap ( 1/2" ), I tested it on a piece of Lexan plastic first and Next it was onto the reactor lid and I will let the Pictures tell the rest.
