Lowering pH with CO2

[mas985]

One gallon of muriatic here costs only $3, so the comparison is even worse.

Yes you are right! I pay 8$ / 2 gallons not 1 so it would be $.25 / dose. Much better than dry ice. My bad.

Just found this:

25 lbs for $40 delivered. So that is 80 doses for $.50 per dose. Muriatic is about 8 oz for a .2 PH change or 16 doses per gallon @ $8/gallon or $.50/dose.

Oh well.

Muriatic acid isn't 8 dollars a gallon where I live - It's closer to $5
