In the PoolMath CYA section, to go from 0 to 40 it says "Add 64 oz (4#) by weight or 67 oz by volume of stabilizer"
Is that pure CYA, dichlor, or trichlor? The reason I ask is I just emptied and refilled to lower my CYA, added about 2-3# of CYA to a ~12,000 gal pool, and the CYA level now reads ~50 (dipstrips) so I have a higher CYA than I expected.
Trichlor only contains about half CYA by weight, but pure CYA is pure CYA.
What is the PoolMath calculator based on?
Thanks for running a great forum!
