I've become lost: bleach or CaHypo shock

[pairadocs]

thank you.

it seems that it is mostly a convenience debate - gallon jugs, or small bags that must be dissolved. Cost is relatively the same.

I think it would take 2 1/4 gals of 5% regular bleach to equal one pound of 65%cal.hypo....That walmart 54.6% bag sounds fishy to me.....Oh by the way I pay $2.15 per pound (thats including shipping) of cal. hypo from "in the swim".
Although it does cloud the water some what, if you put it in late in the evening its cleared up by morning.......You must make sure that all the cal hypo disolves and you should brush the pool floor after you add it, if you dont it will bleach your liner.........I like to use cal hypo as shock but I wouldnt use it just to keep my residual up unless I could find a cheap supply of those plastic covered cal hypo sticks, does anyone even sell those sticks any more???

I use cal hypo in addition to bleach and pucks (only when CYA needs to go up). Got a 100 pound pail of CH 67% in 2003 for $116 at a pool store. Of course everything has gone up since then. 100# is going to last me 3 seasons. Lot cheaper than individual bags. I'm careful not to mix the types but I do throw the CH right in the skimmer and let it dissolve in the filter. It does dissolve pretty fast. Also my calcium hardness is low so I can get away with adding a little more and having the convenience.

Just double checked my math with BleachCalc and it said it would take 3 cups, which is 24 oz. of 5.25% beach to raise 1000 gal. 10 ppm, 2 cups and 5 oz (21 oz) of 6%, and 1 cup and 2 oz (10 oz) of 12.5%.

Don't know why I didn't do that in the first place instead of figuring it out on a calculator. It took me a good 10 minutes the first time to do the calculations! Once again Michael's BleachCalc proves it is worth it's weight in gold!

HTH (and some other companies) are selling Cal Hypo with fillers in them that reduce the amount of chlorine so, I assume, they can sell them cheaper at discount outlets.

So according to that it would take 1 1/2 gals of 5.25% bleach to equal 1 pound of 65% cal hypo? Thats good information to have if your switching back and forth from bleach to cal hypo (like I do)..........
