Best place to buy CYA

[gagan]

Need to buy some CYA for my pool as it's current less than 30... Any recommendation where to buy it?

Also, any recommendation of Powder form vs liquid form?

I buy mine at a local professional cleaning supply store. They sell pool chems for less than the local "pool stores". You might check around and see if there's something like that in your area.

I buy CYA at Lowe's. It's 100% CYA and comes in a granule form.

I only need to add small quantities of CYA and do so by adding 99% dichlor that I bought at Sam's Club. (Guru-Ben's recommendation). Adds CYA and FC in manageable quantities and is readily measurable.
