should I buy cal hypo 68%, if cheaper than 73%

[meestahmarc]

so. am I thinking logically here. my choice brand of cal hypo shock 68% is 25 percent cheaper than the 73%. seems like I'm better off buying the lower strength since the price is so much lower. I can just add a little more if needed based on pool math calculator.

Sounds like simple math. 7% less material for 25% less money. I've done that math on chlorine many times. 6% vs 10% vs 12.5% for example.

yes, exactly...
