We do not recommend the liquid CYA simply because it is so expensive.
Whatever advantage you are imagining you get from "having it done right away" doesn't really exist. So you are just spending money you don't really need to spend.I'd rather pay a bit more and have it done right away than wait a week.
To add 50 ppm to 23,000 gallons you would need (23000/10000)*(50/32) = 3.59 gallons which at $27 per gallon (about the same price as poolgeek.com, by the way) this is $97. You say you used 3 gallons which would cost $81 so that would add 41.7 ppm CYA, not 50 ppm CYA. You say that the required amount of pure CYA from Lowes was $8 less so $73, but that is a TERRIBLE price for pure CYA unless some calculation was done incorrectly.Leslie's had liquid CYA for $47/gallon in the store, but they price matched a $27/gallon on their own website. That's only about $8 more than the granules at Lowes, and it was instant. I used 3 gallons and took my pool from 0 to 50.
