Our current test results are:
How long should I let the swg run to keep our FC at 4-5? We are running it for 7 hours a day right now and it's just not keeping up. I was hoping 7 would be enough because the next setting on our sand pump jumps from 8 hours run time to 12 and I really didn't want it to have to run that long every day. The manual says 6 hours should be enough, but obviously it's not. Please help.
