Na di-chlor vs bleach cost

[halds]

Thanks Dave,

I just read PollDoc's post on a similar topic here today, and learned my lesson for the day.

Penny wise and pound foolish. I think I will stick with my dichlor method and not worry about whether I can be saving money with bleach. Perhaps in the late sumer when the CYA level begins to soar, is a good time then to switch over till the end of the season.

I guess it was good to point out that bleach may not be a good choice for some people....

Just for my own sake of knowing, dichlor should have twice the chlorine power of hypochlor with equivalent percentages of total weight of the products?

I've never done a cost-equivalence comparison, but I agree that DiChlor DOES have its place. However, I suspect it will turn out to cost more than bleach.

I'm still using up the DiChlor I bought a few years ago, but I ONLY use when my CYA is low and I want to raise it--I also make sure my pH is high before I use the DiChlor.

I especially like to use it in the spring at opening as my CYA has usually (like a lot of folks) fallen off over the winter.

But once CYA is where I want it, I'm done with Di-Chlor, unless it's an emergency and I'm low on bleach.

I have also found it VERY interesting that DiChlor, while it adds CYA, doesn't seem to add nearly as much as Tri-Chlor tabs do.

Could someone explain why DiChlor is only marketed as a compound with CYA? Is it not stable in granular form without CYA? Seems like it would be more marketable if one could purchase with or without CYA added...

Because then it wouldn't be Di-chlor. Tri-chlor has the same problem. By definition when both release their chlorine they produce CYA. It's not added, it's part of the chemical process.
