New Thread with my results of first test

[Tom.B]

The CYA I have is Leslie's conditioner/enhancer and claims a 30ppm increase per 2.5 lbs. per 10,000 gallons. So I will add all four pounds and see where I am in 48 hours.

[PoolDoc]

CYA dissolves SLOWLY. If you add CYA via the skimmer, and backwash or clean before you've run the pump 72 hours . . . you may lose the majority of what you've added.

[Tom.B]

Can I continue to add Chlorbrite to the pool while I wait for the CYA to dissolve?

[PoolDoc]

What's Chlorbrite? Leslie's had several chemicals with that name.

In general:

1. Never, EVER let any chemical (except maybe borax) come into direct contact the cyanuric acid. Be especially careful with cyanuric acid + calcium hypochlorite.

2. In general, as long as you follow #1 above, you can treat your pool normally while adding CYA.

But that page say 99% while the bag says 55%. Oh jeez... I am afraid I know just enough to get me in trouble around here. Please bear with me while I am still learning.

[PoolDoc]

It could be 99% dichlor dihydrate which would be 55% available chlorine. If so, it's fine.

If you're not sure, post the EXACT ingredient names & % you see.

BUT . . . be sure to continue to use bleach, till you know. Don't let your pool go green, while you get answers to your questions!!

[Tom.B]

I don't have straight bleach, yet. I hope to get to Wal-Mart today to stock up. I gotta use what I got ;-)

[Tom.B]

It could be 99% dichlor dihydrate which would be 55% available chlorine. If so, it's fine.

That appears to be correct. So after 4# of CYA last night and a 1# bag of dichlor first thing this morning, here are the latest numbers. (and I think I am getting it right, but still need to go get bleach)

Free Chlorine 6.5
Combined Chlorine 0.5
PH 7.2
Total Alkalinity 90
Calcium Hardness 390
CYA (Stabilizer) 50-55

(Copy/Paste from my spreadsheet... sorry)

So I will check it again in the morning and see what, if anything, I lose at night and one more time tomorrow after work to check daylight loss. But I am feeling better about things. Algae seems to be gone (or at least under control) and let's hope I have the persistence to keep this up.
