Just got the MSDS...

Seriously fed up with the chems now. I go but the recommend stabilizer, but looking at the msds, it says TRIAZINE.. Is that the same??

That's the same. It's just the chemical name for Isocyanuric acid. It shows 97 to 99% so it should be exactly what you needed.

2 kg should have added about 30 ppm.

Phew..

So now.. Why did my CYA go from 25 to 30 only?

 

[Bama Rambler]

Testing error I really don't know. Like I said, wait another day or two and then see if it shows up.

Will test again today / tmr to see if CYA shows up.

As an aside, I was in Buffalo, NY over the weekend. Found HTH stabilizer/conditioner that stated 96% CYA at Walmart for $15 for 1.8Kg. This one - http://www.walmart.com/ip/HTH-Stabilize ... r/17043638


The one I bought here in Toronto was 1kg for $13! This one

Bought 6 of them

Are those better (pricing) and type?

Any comments on the Stabilizer i bought from Buffalo? Better than the one we have here in Toronto?

Just tested the water and here are the results:

Salt: 3400
FCL: 3
TCL: 3
CCL: 0
PH 7.6
TA: 100
CYA: 30
CA: 120

I see that CYA is low and TA is high.

Seeing that we will be changing the liner in a few weeks, or closing the pool and changing the liner in the spring, is it necessary for me to add CYA?

If your SWG is able to keep up, then you do not have to add more CYA; although a higher CYA may result in the ability to reduce the SWG output and thus extending its life span. Also, with lower SWG on time, your pH will not be driven up as fast.

Thanks. I am running my pump and swcg about 10-12 hrs a day on V1 1200 rpm and 35% cl generation.

Is the stabilizer I bought from Buffalo ok?

Why wouldn't it be? It is the same ingredient. Many people use the HTH from Walmart.

Thanks. Was just checking to make sure I have the right stuff. Will return the one I bought here locally as it was double the price.

I use the HTH and I have decided I think HTH is a pretty responsible brand.

Many of the products they sell are Cal Hypo based and less prone to cause CYA issues and their labeling and brochures mention that you need to control your CYA. Also, they actually sell the 6-way kit that measures CYA. To my knowledge its the only non-TF or "professional" kit that measures CYA.
