Do you have access to Amazon Prime? This is the stuff I like - called Puri Tech and I use them for CYA and Calcium Hardness Increaser. Pure stuff, priced fair and quick shipping (in the states) Amazon.com : Puri Tech Stabilizer Conditioner Cyanuric Acid UV Protection for Swimming Pools and Spas (25lbs) : Garden & Outdoor
I have Amazon prime for Canada. Here is the message I got when I try to buy what you linked

So far I added 4litres of acid. That brought the ph to 7.2 but the alkalinity is still at 150. At this rate it will take like another 16-20litres to get alkalinity to proper level?? This is nuts
Shaney, don't worry so much about the TA being above the range. As you lower your pH, the TA will drift down as well.

I was worried about that. I'd read other posts that have made it sound like it's not that simple up north of the border... sorry, but try finding a source and keep it simple and pure. The crazy thing about this method is that it really is simple. Nothing flashy and once you get the hang of it, you really rarely have to do much. Read, read, read these posts. The more you read, the more it will make sense. Bleach / Chlorine, Muriatic acid, CYA, Calcium Hardness Increaser, baking soda and borates (for me). That's it. Find your best sources, but in the bulk you're comfortable with and add slowly and test until it all comes together. Once it does, you'll be amazed at the simplicity - Good luck!

This - don't worry about TA. Higher TA means your pH will rise up more quickly, but when it does, you will add acid and that will lower your pH back to what you want and start to lower the TA a bit. As time goes by, your TA will fall with more acid additions and the acid additions will become less frequent.

Ahhhhh, now I get it ! I thought I had to have perfect TA or everything else is screwed. Thanks, I appreciate the help.
So when do I worry about the calcium hardness that is at 560 ppm today ? The pool store gave me this product and told me that will take care of it. I was skeptical and wanted to talk to you guys first. Have a look at the pic and let me know what you think. I have no clue what this stuff is.

Are you using the PoolMath app? If so, you can better deal with high CH by turning on CSI tracking and keeping your CSI on the negative side (0 to -0.3). This will help prevent scaling on your SWG. Vinyl pools don't normally need to have CH tracked or dealt with but heat pumps and SWGs can get scale so you can use CSI to offset the hardness.

Out of curiousity, have you tested your fill water's TA, pH, and CH?

I started using the app yesterday. I'm trying to figure out how to re enter a new day of testing. It seems like I can only go back in to my testing from yesterday and modify. Also, all the stuff about CSI is beyond me. As of right now, that is just a TV show. I dont even think my k2006c has a test for csi.

If you have not purchased a subscription, then that is correct. It will not store your logs.
You can also use the old web version here: PoolMath

Have you upgraded to the paid version of the app? Are you using the windows version or an app on your phone? On the phone, there should be a new log tile to touch. On the windows vesion, click the + sign and select test results. You do need the subscription to save multiple logs.

CSI stands for Calcite Saturation Index. The app will calculate this for you based on pH, TA, CH, CYA, and water temperature entered for your test results.

Just found the info on CSI in pool school. THANKS!
I will purchase a subscription to the app now.

How does your water look?

The CH is really high. Could there possibly be a testing error on that one? Have you used cal hypo at all? Have you tested your fill water? I believe vinyl pools do ok with high CH, but I’ll summon @mknauss and @Richard320 for that.

Assuming the CH is something we can ignore for now, I would start by lowering your PH with some Muriatic acid. Target 7.6, and retest after an hour or so. That will help you from overshooting. Don’t worry about TA. That’ll come down over time as you adjust PH. Is your salt generator running? Your FC is not out of whack for a CYA of 20, but that is not within TFP guidelines. Although, you’ll want at least 60 ppm CYA if you’re going to follow TFP methods for a salt generator pool. I’d calculate the amount you need to go from 20-60 and then add 1/2 of that and retest. Add again once you’ve confirmed a good reading.
I was out of town, so I missed this.

I just skimmed the replies, so forgive me if I being repetitive.

I wouldn't trust those CH results unless the test was done with a speedstir. In my experience,m the CH dropped about 200 ppm -- rough;y 1/3 -- when I switched from manual swirling to speedstirrer.

High CH can lead to scale formation, same as with any other pool. However, pH and TA have far more effect upon CSI than actual CH. Once things stabilize and you have run a full battery of tests, then plug the nu,mbers in to poolmath and see what CSI is.

Good to know about the speedstir. It's pretty difficult to get in Canada. I will try to find someone who can ship it up from the US for me.

Do you have any idea if this chemical is legit or not ? Pool store gave me it to lower my CH. I don't want to use it if it is not recommended on here.

Only way you can reduce CH is by doing a water exchange. That stuff they gave you just keeps everything in suspension and you have to use it weekly.
