For only a little more that a bottle 1/4th the size, this is a good deal. Now that I have a lot of it, I'll test more often.

I use this to test water in my pool. Bought it before works like it's supposed to.

When you need to refill your reagent for your test kit, consider this.Way more product than the little bottle not much more.Same stuff, cheaper per test.

Useful to have the CYA test regent in a large amount. However, it could use an attached flow control attachment to prevent spillage.

This is an excellent value compared to buying the 2 ounce size. If you test for CA on a regular basis then this is your best bet. The bottle I got was recently made and shipped in 2 days via Prime.

Best buy for the amount of re-agent needed per test. This will last a long time. It is a test that has to be done at least twice per year when you use salt system for your pool. Usually each test will take 2-4 attempts spread over a few days. Well worth it and it works perfectly.
