That is only adding 0.7 ppm FC per day. Way too little.
Once your finish SLAM, set the SWCG to 100% and run for at least 12 hours. That will give you 3 ppm FC per day. Might be enough in your climate. If FC goes down, raise it to 16 hours
I’ll increase the time I run the the pump and swg. I didn’t think in last years I ran it that long.
Just checked the levels. CYA is 50
