Be sure to check and adjust PH before starting SLAM, as FC over 10+ causes a false higher reading. (reagent reaction)Sub pump is out, main pump is back on, and I threw my S200 in to clean some of the algae and to further mix things up. Also added a fresh skimmer sock and opened the intake and outlet for the spa. I'll put a gallon of chlorine in tonight and run my pump 24/7 until SLAM is complete. I planned on another gallon of chlorine each night until Saturday morning when I start SLAM in earnest, plus whatever chemicals tomorrow night's test indicates.
Paging @InyoRob @InyoMattSemi-related, does anyone know what parts I'd need to rebuild the multi-valve on my filter? It works fine, it's just a bit grindy when I use the valve. If opening it up and spraying some lubricant in there would do the trick, I can do that too. Pics of the valve and filter label attached.
It doesn't go bad unless it gets wet, as far as I knowHow well does solid CYA keep? There was a container of something by my pool equipment that I hadn't cleaned up yet, and when I just checked it was CYA. It's in an opaque plastic tub, well sealed, still appears dry inside. But it's also been outside for at least a year and a half, and I'm not sure how much longer than that.
You might want to pull that out and put it in a bucket of water, until you verify you can get FC to hold.Yep, it was still freely moving granules. +1lb into a sock in the skimmer, per PoolMath. I'll give it a squish when I get home tonight.
