Very low cya

[mirhath]

I tested the CYA levels in my pool. I filled the cylinder completely to the top and could still see the black dot. What is the best method for adding stabilizer?
I am needing to start the SLAM process.

Solid/granular cyanuric acid (CYA) should be placed in a sock and the sock put in the skimmer basket or suspended in front of a pool return. After adding CYA you should leave the pump running for 24 hours and not backwash/clean the filter for a week. Squeezing the sock periodically will help it to dissolve faster. Test and dose chemicals in your pool assuming the amount of CYA added is in the pool according to Poolmath. CYA can be tested the day after it is fully dissolved from the sock.

Do you recommend raising my CYA before I start SLAM? I've already added quite a bit of LC. I tested for the first time today.

finish your slam and then do the CYA.

What should my Target FC level be? The lowest amount of CYA on the chart is 20.

 

[mknauss]

You should have at least 30 ppm CYA in your water for SLAM.

Ok. Then I have to raise my CYA levels first. When I tested today I could see the black dot with the cylinder full! I added a sock of stabilizer to the skimmer.
