About 3 weeks ago my 3 year old threw 3 dirt clods in our above ground vinyl pool (14’x42”). I immediately shocked and vacuumed, but it seemed since my dirt is VERY fine, the filter (a cartridge) wasn’t catching it all. I would have a layer of dirt on the bottom even after running the filter 24/7. I did some research on here and bought a 5 micron “slime bag” and attached it to my return. This seemed to work (mostly) but I’ve still been getting a bit of sediment collecting on the bottom.
In addition to this I tested yesterday and everything was within my parameters. I added about 3 cups of 6% bleach tested before my boys swam all afternoon but this afternoon I tested and it’s pretty much GONE. My combined chlorine is now 1.5 so I’m shocking it. it’s been really hot here, so I tested my CYA and it was at 30, which is at the bottom of the guidelines?
When I first started out with this pool (it’s my first) I miscalculated and added too much CYA so for a while the pool has been sitting at 60. I tested it last week and it was 60 still so either I didn’t test right (I guess it has to be in sunlight ect ect) or I lost a bunch in a week. This is possible because in the process of jury rigging my return to take the slime bag I lost a bit of water (like maybe more than a bit haha). I just read that people in super hot areas (I live in LA) like to keep their CYA high - is there truly a difference?
So I guess what I’m asking is should I be adding more CYA? I’m obviously shocking my pool right now, and I will be doing an overnight test. Should I add the cya before I shock or after?
