concerned about TA and CYA level

[polyvue]

I am running out of cyanuric acid reagent. Is this something I need to order from Taylor?

I agree with PoolDoc that you really don't have to worry about CYA (since you've just tested it and most people only need to test CYA a few times during the pool season) but you've asked a question I can answer. If you think you'll be testing frequently consider purchasing CYA reagent in larger quantity. To reduce overall shipping costs, try to anticipate what other items you're going to need and group them together. Or is this advice a bit obvious?

2 oz and 16 oz sizes are heavily discounted at the following suppliers:

Spspools-spas.com
Amatoind.com

32 oz size available at slight discount from PoolWeb.com

I've found a source that beats all others on larger size Taylor reagents but I have not had occasion to order from them (there may be minimum volume requirements): nationalpoolcare.com
