I have a reef keeper elite and I tried to calibrate the ph probe that's inside my calcium reactor and it's not working. The probe is relatively new (less then a year old) and I've already ordered another one just in case. If anyone is familiar with the reefkeeper and has upgraded the software before, I could REALLY use some help getting this P.O.S. working! More than happy to give someone some compensation for their time. PM if you have anytime in the next day or 2 as I have to get the calcium reactor back running!
