Efficiently adding CYA

[docsobeck]

that's what i was thinking. i keep some pucks on hand for when we're away for long weekends, so i figured if i already own the CYA, i might as well put it in that way.

I wrote a post on the Cost Comparison of Chlorine Sources that shows that chlorinating liquid and bleach are usually the least expensive sources of chlorine though Cal-Hypo can also be inexpensive in some areas. Trichlor is close behind but isn't as cheap as it first appears because of the chemicals needed for pH adjustment. Dichlor is more expensive and lithium hypochlorite is ridiculously expensive.

I also wrote a post on the Cost Comparison of Cyanuric Acid (CYA) Sources that shows that accounting for the chlorine that you also get with some of the sources, the least expensive way to go is to use pure CYA though using Dichlor is close to the same and Trichlor is a bit more expensive. However, these differences aren't huge. At least with Dichlor, it dissolves quickly in case you wanted the CYA to rise right away.
