Just tested with TF-100, what to do now?

[Aneley]

Follow the CYA test instructions that I linked, do it in the daylight tomorrow and report results.

Okay will try it again tomorrow, thanks!

Don’t use that stuff, it’s overpriced lower concentrated. Use regular muriatic acid from Home Depot, etc.

Edit: hang on. Cyanuric acid is not the same as acid for pH.

Cyanuric acid = stabilizer=CYA. This is used to protect the chlorine and is what dictates how much chlorine you need in the water.

Muriatic acid = the stuff that lowers your pH.

It’s maybe a little confusing now, but you’ll get it and people around here will help.

Okay that makes more sense, thanks! I'll see if I can just get the muriatic acid from home Depot then. But I'm guessing I should also figure out a good place to get cyanuric acid

So I downloaded the pool math, but I can't seem to figure out how to use it. I don't know the information on my SWG, since the previous owner's didn't really leave me with that information. Really finding this confusing

I realized since I was using the liquid chlorine to shock the pool, I could just input liquid bleach into the app instead of adding the SWG information. The app told me to add 30 oz of liquid chlorine to my pool. Hopefully that sounds right

You can likely get that at Home Depot as well. It’s labeled “stabilizer”

When you open up the FC tab in the app, click the little switch labeled “SLAM” and it’ll tell you how much chlorine to add.

30oz sounds like that just to get it up to normal range.

If you ever get near the Home Depot in Claymont, DE, they have Muriatic Acid in stock. The lot is from the middle of last year, and the boxes are in terrible shape, but the bottles don't seem brittle yet. I've been able to get 50% off of them this season by getting a Manager and showing them the condition and production date. Whatever acid you find, make sure it is not labeled "Green" or "low odor". That is not what you want for your pool.
