With your CYA at 55, it is 60 as we round up. Your shock level is 24 according to the chart.Swell, more money down the drain. Just tested the pool, and FC is down to 7. Tested it twice. Pool looks great, no sign of algae, but I am sure I should not have lost 10 ppm of FC in 10 hours. I am going to get the FC up to 30ppm, I just hope I don't bleach out my new liner. If I am doing anything wrong I would really appreciate advice from the experts.
CarolineM, What does that mean?With your CYA at 55, it is 60 as we round up. Your shock level is 24 according to the chart.

If you look at the chart I provided the link to it shows if your CYA is 60 your SLAM level for chlorine would be 24 ppm not 30. No point in going higher than the recommended SLAM level, as you don't want to risk bleaching your liner.CarolineM, What does that mean?
Wish I would have realizes this years ago. Always thought, because of 60*(not recommended) in CYA/FC chart. That CYA Had to be 70-80 for SWG pools.You can add bleach and stabilizer at the same time, however when you are slamming you do not want to raise the CYA above 30. Leave it where it is for now.
So, I read through this entire thing while bored at work (I'm here only in case something goes wrong at the moment) and I hope you don't mind me sharing some of my thoughts, to try and get this solved for you.Thank you for the responses. I checked the chemicals early this morning.
FC - 30
CYA - 40
Checked everything else, but no need to report since FC and CYA are what is important at this point.
Unfortunately, I work long hours during the week, so it is hard to check chemicals frequently. Won't be able to check again until very early morning in the dark.
I will target FC of 24. I do brush whenever I can. Also run Dolphin automatic cleaner, and bleach filters are each use.
Yes, you need to check the pool more than once a day during a SLAM. Ideally, from what I read, multiple times a day, but a minimum of once at night and once in the morning. They need regular checks and additions even outside of SLAM, which ideally will prevent the pool from needing SLAM in the first place.Well I am sure all of you who read this thought, we if they can attend to their pool daily, nothing will get resolved. Yep, you are right. Haven't checked the pool for two days, and I just got home from work to see algae back in the bottom of the pool. Tested FC - 12 and CYA - 30 only. I am going to be able to babysit the pool for the next three days.
According to old pool math, it says I need two jugs of bleach and 6 lbs. or 1+ gallons of stabilizer. I think I read where you should not put bleach in the pool the same time as stabilizer. Not sure which is more critical, so I am going to start with bleach tonight. I am going to take the cartridge filters out tomorrow and clean them thoroughly. Plan to get in the pool and scrub the walls too.
Appreciate you sticking with me

The article on SLAMing mentions this:In order to start the SLAM
SLAMing an outdoor pool is most effective when CYA is around 30 to 40. Below 30 you lose too much chlorine to sunlight. As CYA goes up, SLAMing requires more and more chlorine, which starts to get impractical around 80 or 90. With CYA above 90 we recommend replacing water to get CYA down before you start the SLAM process.
