Adding Calcium Chloride vs Water Hardner

[bigroller70]

First of all let me thank all of you!! This is my 4th year of having a pool and the first three were horrific. I couldn't keep the water right and I spent more time trying to fix the water than I did swimming in it. This year however, is different. I purchased a Taylor test kit like many of you suggested and followed the TFP method and wah-lah.. trouble free pool! What a joy it is to have a pool that's trouble free!! My present readings:


FC 3.6
CC .2
PH 7.4
TA 100
CH 90


According to pool math, I need to add 23.6 lbs. of calcium chloride. I purchased a 50# of Downflake Xtra calcium chloride at CO-OP this morning and noticed that it's not 100% pure. It also has water, potassium chloride and sodium chloride in it and it says it's 83-87% pure. My questions is, will these other ingredients be harmful in any way? My grandsons swim in the pool daily and inevitably swallow some water. Also, when I dissolve this in a 5 gal bucket, how much should I add at one time? 5#, 10# or 23#? Thanks again guys!

You have a vinyl liner, you don't need to mess with your calcium level.

Those other ingredients aren't toxic. You know Sodium Chloride is salt. Potassium Chloride is what's in "No-salt" that people with high blood pressure use on their french fries.

As for adding it, you're asking the wrong guy. I'm always trying to lower my CH number. You could just come visit me and bring a barrel and I'll send you home with enough water to boost your CH in a hurry.

^^^ Donaldson is right. You dont need to add any CH to vinyl pool.
If you can, return the stuff and get a refund.

Thank you all for the speedy responses. If I don't need it in the pool I'll just hang on to it and use it this winter for ice melt. Thanks again.
