Cya testing

[RedwingT]

Even thou I just added a lb of CYA on Tuesday, I couldn't wait to try the test. I got a reading of 40. I am out of reagent 0871 as stated above and did my final FC/CC test until the replacements get here. My results below: 10ml tests
FC 15
CC 0.5/1 Hard to tell for sure last drops in bottle and they just flew out.
pH 7.4
CYA 40

Going to calculate the amt. of bleach to put in to reach shock level of 30 with a CYA reading of 30-50. I have a group coming over to swim on Sunday and would like this last little bit of algae killed and vacuumed up by then.

On Ben's best guess pool chart there are 2 shock levels...what is the difference? One is 'SHOCK' and the other is +SHOCK+

The SHOCK is for stardard shocking of the pool and the +SHOCK+ is for Mustard Algae shock levels.

Thanks jwhouse, if I had to guess that is what I would have thought. Now it's confirmed.

Thanks Dave! Sure beats the pic of the ground before installation!

Wanted to give a shout out to DiscountPoolMart on Amazon Marketplace. I ordered the 3 reagents on Wednesday August 8 and received them today Saturday! Estimated delivery was August 15! So I actually only went 1 day without being able to test! Fast A+ service!

I bought my kit at amazon, but also visited the taylor technology site. they also have what you'll need. MY CYA level has dropped to 30. I have isocyanuric acid granules that I used before I converted from SWCG to BBB. Is it OK to still use that?

It's fine.
