How much stabilizer should I buy in this economy?

[DeptOfMeteors]

According to PoolMath if I buy BioGuard Stabilizer 100 (2.5kg) Chlorine Stabilizer (SKU 1303) : Amazon.ca: Patio, Lawn & Garden (that's right, I'm in Canada) and I add all of it to my pool, the CYA will rise to just short of half of what I need it to be (60ppm). So I just wanted to make sure before I buy 2 or 3 of them, that I'm getting the right thing in the right quantity.

Keep in mind, when I bring "economy" into this that it isn't just about pool chemistry, but also how much I need to ride inflation. So I don't want to buy more than I will need when prices go down, but I also don't want to find I need more and the price has doubled! (Which it might well!)

Looks like you'll need about 5.2 kg to go from zero to a CYA of 60. Stabilizer, along with many other chemicals, has really jumped in price. Same thing down here in the states.

You can also get at Canadian Tire the 900g size package for $16. Smaller package but overall less money ...... Might help you ride out the inflation

I guess folk are going to put more effort into timing their backwashes so that the least valuable chems are lost.

I hate going to Canadian Tire! But I'd make a deal w/the devil to save a buck. I take it you mean General PDP Template. You certainly get a lot more kgs for your buck, but it's a different manufacturer. Are Aquarius products every bit as good as BioGuard? I tried Googling "Aquarius BioGuard reviews" but it looks like not that many people are asking that question.

I'm familiar with Bioguard brand as well as I used to buy that from St. Lawrence Pools. I haven't personally used the Aquarius branded product but I believe it would work fine and I wouldn't be afraid to try it. I think Bioguard just charges more for the same material. You'll want to add this to your pool in such a way that it doesn't directly touch your pool's liner. You'll see the sock method referenced here a lot - put the concentrated CYA into a sock and have to tied off in front of a return. Let the material slowly dilute into the pool water. I wish I'd known this before... Having the stabilizer dumped directly into the pool isn't idea as it's a type of acid and can have negative impact on liners.

Really?
1 ppm = 1 milligram per kilogram = 1 gram per m3
So if you want CYA=60 in a 36 m3 pool, you would need 60 x 36 = 2.16 kg

I had the idea that TFP only changed the sigs in future posts and left the old ones as is. Well, if it did, you'd see that I thought my pool had much more capacity

That explains the difference. I ordered cyanuric acid yesterday and calculated I needed 3 kg for a pool of 44m3 to raised CYA from zero to 70ppm, so I was surprised that you would need more.
In Spain, cyanuric acid is much cheaper:

Maybe they ship to Canada.

Unfortunately I cannot buy any decent test kit here.
