# Thread: Closing Questions Regarding Slam

1. ## Closing Questions Regarding Slam

I'm preparing to close for the first time. I'm using the PoolMath and Calculator to calculate the dosing for the SLAM...awesome tool btw. With my CYA at 48, the Calculator indicates that I need to bring FCL up to 19 ppm to achieve Shock level. PoolMath tells me I need to add 596 ounces of 8.25% Bleach to get to 19 ppm. I'm assuming that 596 is a weight value and NOT fluid ounces.

Am I doing this correctly?

I noticed that the "other effects" indicator says this much bleach will raise salt by 24 ppm. Should I be concerned by that? Does salt dissipate or does it accumulate each time I add bleach?

My levels today: FCL 5.6, CCL 0.1, PH 7.6, TA 105, CH 197, CYA 48, Pool Temp 66 degrees

How/where are you getting those test numbers?

3. ## Re: Closing Questions Regarding Slam

I'm using a Lamotte ColorQ test kit. I'm fairly confident in the accuracy.

4. ## Re: Closing Questions Regarding Slam

I'm suspicious of test results accurate to 1ppm, but for the sake of discussion let's assume those are good numbers.

The oz is liquid, like a bottle of bleach is 128 oz. That amount of salt is so tiny it doesn't matter in the slightest. Keep in mind SWG pools have salt levels in the thousands of ppm.

I'm confused now. All the jugs I see in the supermarket come as 121 oz containers.

The quantity of the jug of bleach doesn't matter, it's how many ounces needed to get the acquired amount. Correct??

Yes, Great Value bleach comes in 121 oz. But like kywildcats said it doesn't matter. If I were gifted a pallet of fresh 1/2 gallon bottles of bleach I would take them!

8. ## Re: Closing Questions Regarding Slam

Okay then. So I just poured in 5 jugs of Great Value Bleach (8.25%). That's 605 FLUID ounces. If my initial readings are correct, that SHOULD bring me to shock level...YES?

9. ## Re: Closing Questions Regarding Slam

Yes, if the initial test was correct. Let that mix around for a little bit and retest if you like to confirm. I would prefer to see results from the Taylor test kit.

Should really think about getting one of the recommended test kits. The TF 100 with the speedstir are worth their weight in gold.

11. ## Re: Closing Questions Regarding Slam

Understood. I ran out of the 871 reagent, so all I have right now is the ColorQ. For the 1st month I had ColorQ, I was double testing with the Taylor.
