Ok all up til now I have been using trichlor tabs and making adjustments with Bleach. This is becoming an issue now that my CYA is nearing 70. What i am after is a method to automatically dispense the chlorine (bleach) into the pool. I don't want to break the bank doing it though. I will measure the FC this morning and again this evening to get an idea of the daily consumption. I am fine with the 70 cya for the remainder of the season here as I will dump about 2.5k at closing.
