CYA level and SLAMing

[jsw5620]

Getting my pool ready for summer. We have had a lot of rain here where I am at and I am trying to get all my levels back right. After having to drop water levels a dozen times during the rain, my levels were pretty much none.

My levels are
TA=40
FC=2ppm
CC=1ppm
pH=7.2
CYA=0 or not registering

I am using the BBB method. I have the TFT100 test kit. My question is will it be better to raise the CYA to 70 for a SWG pool and then slam or wait until after I SLAM and pass the OCLT to bring the CYA level up?

My suggestion is to first raise TA to about 70 using baking soda. Then add about 30 PPM CYA to use during the slam.

After the slam is completed, you would then raise the CYA to 70ish. Got pics?

What's the recommended SLAM level for a CYA of 30? I forgot to mention I added the baking soda this morning to bring the TA up.

I've used the FC level of 30 a couple years ago, but you can tell it bleached out my liner

Thanks. I saw the chart and have to pool calc app on my phone. Wasn't sure if those levels between CYA levels and SLAM mattered between the SWG & NON-SWG pools. So basically, bring CYA up to 30, FC up to at least 12 instead of 30. Got it!
