Welcome to TFP.

What test kit do you have?

Post the pH, TA, CH of your fill water.

Add 5 ppm of liquid chlorine and get at least 30 ppm of stabilizer dissolving using the sock method ASAP.

Welcome to the forum!
What do you have to test your pool water chemistry?
First, 3 ppm FC worth of liquid chlorine. Get 30 ppm CYA dissolving using the sock method. Check and adjust pH into the 7's. Maintain FC based on FC/CYA Chart going forward.
Add your salt. Add 2/3 rds of what PoolMath says. Let circulate for a good 24 hours and test again using your Taylor K1766 kit. Add sufficient additional salt to reach your goal.
Once you can test the CYA (24 hours after fully dissolved), add enough CYA to reach 70 ppm. Add liquid chlorine to get to target range and adjust your SWCG to generate sufficient chlorine each day to meet your needs.
I suggest you read ABC's of Pool Water Chemistry.
