Feel more confident now! :)

Thank you, Matt. So should I use up my MA and add Calcium chloride?

I wanted to add borates to my vinyl pool couple years ago and never did. Well, now I'm ready to do it by bringing down the TA with MA and aerating water to increase the pH. Here are the readings with TFT 100 kit, FC 6.0 CC 0.0 pH 7.2 TA 60 CYA 50 CH 100 I have about 1/3 gallon of MA left, can...

Attached are the front and back of the instruction paper. Just prepare two solutions with the buffer powder provided in 250ml deionized water if you can get it ( I used distilled water and it seems ok for my testing purposes.) . Adjust the reading on your pH meter with the screwdriver and rinse...

If you live near Menards, they have liquid chlorine - Pool Shock on sale for $1.77/gal. It's 12.5% Chlorine which is very good. Look at the manufacturing date, a Julian date, such as 170176 which is 176th day of the year 2017 (June 25th). Higher the date, fresher the pool shock.

Adding a button for manual/auto vacuum would be nice! Great app Russell! Thanks

Home Depot is the nearest store for me, I'll check that out first. Thanks.

Re: SilkGuard® Tabs or Clorox Pool&Spa XtraBlue 3" Chlorinating Tablets I can ask my friend's son to stop by and top off the feeder once. That should do it, I hope! Any suggestion for a 99%Trichlor tablets? which store, brand? - - - Updated - - - It's available at my local Costco...

I've been following the TFP method for the last year and a half and my pool is crystal clear with lot less chemicals being used. So happy to have found this site; my dilemma is next month we'll be away from home for three weeks and I need to use chlorine tabs to keep it clear. In the past I...

[B] James, thank you for the reply. Does it mean that seven people in the pool for one hour will require about a cup of 12.5% chlorine, no matter what the size of the pool is?

4 grams of Chlorine gas = ____ oz. of 12.5% bleach? I couldn't figure out the formula using the poolmath. Thanks Matt!

I did the Pool Math for 1 gal pool size and added 1 oz. 10% bleach; result was FC 781; divide it by 12 (1oz = 2 Tablespoons = 6 teaspoons = 12 one half teaspoons) = 65 ppm. So for 32 ppm in 1 gal water, it only needs 1/4 teaspoon 10% chlorine unless I am calculating it wrong.

Thank you Ping and Camueller, I will look it up and get the reagents asap.
