I've lived in this house for almost 2 years and have had this issue since moving in to the house.
The Dig220 says my salt level is anywhere between 6300-6600 ppm. Testing the water for salt usually shows around 3300ppm. Everytime I shock the pool and get all the levels where they should be according to the pool store read outs I start to get green algae build up after about 1.5 weeks. And this is with no errors on the Dig220
Here is my set up:
14000 gallon salt water pool
Intellitouch pool spa control system by pentair system i5
Pool Pilot digital 220 by autopilot.com
SC-36 running at power level 2
60 sqft DE filter
Whispher flo high performance pump by pentair 2hp 1.3sf
I would normally run my cell 8 hrs a day. Since moving in to the house I have replaced the cell cord and the salt cell from an sc-48 to an sc-36.
I am spending too much money on chemicals having to kill the algae. Luckily the last several months have been too cold to want to get in the pool but summer is right around the corner.
Has anyone had this error? Do I need a new board or system all together. This is pretty frustrating.
Thanks in advance,
