Re: Need 2nd Opinion on % vs Volume vs $ calculation/assumptuion
2,85L of 4% at $1/Liter = $0,09/ppm
7000g of 62% at $87 = $0,2/ppm
You would think the $1 bleach is quite inexpensive, but it's actually twice as expensive as the cal hypo from Trevi or the 65% stuff at Club Piscine.
The Costco HTH cal hypo, 22,7 kg for $94,99 is even more expensive at $0,06/ppm. You'd think they would be the cheapest.
