Calcium Chloride

[ZSipz]

Does anyone have a (larger) bucket/container recommendation for mixing CC with their pool water (per instructions) as the reaction exothermic and i definitely felt like the container I used definitely warp/ possibly slightly melt the first time I did it…

Calcium products should be spread across the surface of the deep end of the pool, and brushed until dissolved...

Recommended Pool Chemicals

Which should I buy? TFP's recommended pool chemicals are cheap, easy, and won't unbalance your pool water.

Forget the instructions.

I slowly broadcast the calcium chloride using a scoop onto the surface of the pool. If any settle onto the pool floor I push it around with my pool brush until it dissolves.

Any risk to blue color of pebble tech?

No, don't let it sit on the surface. Brush it around.

Calcium Chloride anhydrous gives 317.2 Btu/lb. when dissolved in water.

Solubility in water = 74.5 g/100ml at 20°C.

Adding 1 lb anhydrous CaCl₂ to less than 0.3 gallons of water will result in the water boiling (Water temp = 84 degrees before adding CaCl₂.)

Y = Temperature Rise.

X = Gallons of water.

For 1 lb CaCl₂.

Gallons.....Temperature rise (F).

0.12...............317.2

0.161...............236.4 (Maximum Solubility is 1 lb in 1.34 lbs of water).

0.24...............158.6.

0.30...............128 (128 + 84 = 212).

0.48.................79.3

1.0...................38

1.5...................25

2.0...................19

2.5...................15.2

3.0...................12.67

As long as you do not add too much calcium chloride to the water, it will not get excessively hot.

For 1 lb CaCl2.

Gallons.....Temperature rise (F).

0.12...............317.2

0.161...............236.4 (Maximum Solubility is 1 lb in 1.34 lbs of water).

0.24...............158.6.

0.30...............128 (128 + 84 = 212).

0.48.................79.3

1.0...................38

1.5...................25

2.0...................19

2.5...................15.2

3.0...................12.67
