Hi folks,
Here's my issue. After much thought and reading and advice from TFP, I decided to go with a new SWG when I redid my pool back in November 2016. I left the SWG out of the system with a bypass for the first few months since it was cold and wasn't going to be doing anything anyway. In March I put it in service and in June noticed 0 chlorine in the pool and found out that all the lights were out and it was popping it's breaker. I got it replaced and now it's a month old and my filter was cleaned 2 weeks ago. I have been running the pump at 2000 rpm 10 hrs a day and 3000 rpm 5 hrs a day. The lower speed used to be lower but about 5 days after filter change the flow is insufficient to produce chlorine so I upped it. The SWG is currently set to 100% and seems to only be producing at the higher speed anyway. The pump draws only from the pool and then feeds back 50 / 50 to pool / spa. On the lower speed the flow doesn't even put water over the dam wall which leads me to believe that the flow is not even enough to overcome the backflow. I use cellulose fibre in my DE filter and the grids are about 5 year old with a few small holes in corners and along seams. And, they look really dirty even after cleaning with a mild cleaner and a brush. I set the dial after cleaning and it was reading 12 and after 2 weeks is already at 24. Today my chlorine was at 0 again so I took the water to the pool store when I went to buy muriatic acid and they said I had the following: FC 0, PH 7.8, TA 80, CH 280, CYA <20 and Salt 3950. I came home, added 1 gallon of 12% liquid chlorine, 30 minutes later I tested the water and here are my numbers: FC 5.4, PH >8.0, TA 80, CH 380, CYA 50 and Salt 4050.
So, I guess my questions are these: 1. How big a problem are the little (pinky finger tip size or smaller) holes in the grids? 2. How big a problem is the build-up on the grids after cleaning? 3. What else could cause that build-up in pressure in such a short time? 4. Is there a problem with using cellulose fibre in a salt-water pool? 5. I've had trouble with the IC-60 before, could a bad flow sensor be contributing to my problems?
I'm ready to pull my hair out, please help!
