Checked this morning:
FC: 10.5
CC: 2
Based on PoolMath, I brought the FC level up to 12 last night with bleach. It looks like it held pretty well overnight. Now I will hold the SLAM level and wait for the CC to come down and the pool to *hopefully* clear up!
The Sytem 3 filters aren't that bad to clean. I use a small electric pressure washer with a fan nozzle to spray the filters. Don't worry, the pressure is WAY dialed down, and is no more than a hose nozzle, just more spread out. In total, it takes me about 25-30 minutes to clean the filters. I'm just not sure what the middle antenna-type thing is for.
