Instant Stabilizer

[FloridaPoolNewbie]

Anyone using this yet? I've tried it twice and really happy with the powder format, first bag was fully dissolved almost instantly. Second bag some smaller chunks lingered. One pound bag will raise CYA ~12ppm in a 10,000 gallon pool.

-Should I vacuum up or net out these chunks?

-If this is a legitimate CYA option, can we get it added to Pool Math?

Enter each bag as 1 lb of Dry Stabilizer in PoolMath. It is there.

Nothing special about it. Don’t let chunks or powder sit on pool surfaces. It is a mild acid and can stain the pool.

That looks higher than this bag predicts...that raises CYA by 24 based on my pool size. The bag shows 18 for a 5,000 gallon pool. Any thoughts on my cleaning question?

If it does 12 ppm in 10,000 gallons it will do 24 ppm in 5000 gallons.

Actually the math on the package says 20 gallons- 6 PPM, 15 gallons, 8 PPM, and 10 gallons, 12 ppm...so for 5 gallons you can assume 18ppm. When I tested my water, it raised it 15ppm...your mileage may vary.

The bag says "cyanuric acid hydrate", which is different from regular cyanuric acid in that it contains water as part of the molecule, which will lower the expected results.

I don't know how much water the product contains, but I would estimate it at 15% to 25% water content by weight.

There are three forms that CYA could be sold in aside from as the dichlor and trichlor.
Anhydrous
Dihydrate
Liquid (sodium salt of CYA in aqueous solution).

The dihydrate may go into solution marginally faster, particularly if it's essentially dust. The liquid is already in solution so it's going to be the only version that is actually instant.

The active contents of the three do differ.
Anhydrous assuming 100% purity would be 7.75 moles per kg.
Dihydrate again assuming 100% purity would be 6.06 moles per kg
Liquid typically 35% as the salt with maybe 1.5% CYA dissolved in it would give you 1.95 moles/kg, or 2.43 moles/L.

So the dihydrate only gives you 78% of the active content of the anhydrous material.
The liquid only gives you 25% of the active content of the anhydrous material on a weight for weight basis.
