Good strategic thinking, Janet! Yes, I am anxious to get the pH correct since it's a brand-new spanking liner!

Interestingly, I did open a brand new OTO kit that I bought two or so months ago, throwing the little amount left of reagent I'd been using since I opened in early May away (darn--I could've cross-checked). The two kits are identical as to manufacturer, both bought at Walmart. I am leaving work early today (in 3 hours) to take a couple hours of remaining vacation, and on my way to SAMS I'll be going by pool store (which is quite a distance from my house) so I will stop and pick up new pH OTO. It's worth the 5 or 6 bucks to see if there's a difference before I start adding more Borax. That said, in the past I have found that kits made from different manufacturers give totally disparate results, and I try to stick with the ones that Walmart sells -- so perhaps I shall go there instead. It was the kind Home Depot sells that gave me an incorrect reading once. Then again, maybe it was simply on the shelf too long; one must be careful I suppose to draw conclusions too fast.

I'm pretty sure the Borax box was green -- I did a little research on the forum before buying and remembered to look for green box. It showed myraid uses, from cleaning the toilet to laundry booster. Are these the kind of uses the correct, green box describes? Does this sound right? I will check back in tomorrow and let you know what the new pH kit says...
