That is called a beach entry.

The Natural Chemicals liquid has more crap than just CYA.
Well, yes, it's the sodium salt of cyanuric acid, AKA 1,3,5-triazine-2,4,6-(1H,3H,5H)-trione, sodium salt or monosodium cyanurate monohydrate. When in your pool water it forms sodium ions, cynaruate ions, and cyanuric acid, same as CYA AKA cyanuric acid or 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione minus the sodium ions, which are already in your water (and more will be added once you add the salt for your SWCG.


I was thinking the Dichlor from some of the other posts. How does Dichlor come? Powder or tabs? if tabs, should I put it in the skimmer basket?. Thanks for all of your great advice. Also going BBB as needed with the SWCG!
Dichlor is a powder, The disadvantage is that it is more expensive than CYA but it does dissolve quickly so the CYA is in the water faster. However since it also adds chlorine it has to be added over a period of time so the chlorine levels don't go through the roof so it is not a faster way to add CYA (like the liquid stabilizer is) and can actually take longer than just using granular CYA unless you only need to raise the CYA by a small amount Dichlor adds 9 ppm CYA for ever 10 ppm FC added so if you need to get to 80 ppm for your SWCG it will have to be done over time.
HOWEVER, IF your new pool is plaster then you might want to consider using trichlor tabs for the first month (Use a floater, don't put them in the skimmer). They add CYA at the rate of 6 ppm for every 10 ppm FC added BUT they are very acidic and will help you maintain the pH as the new plaster cures.
