Help me decide the best course for chlorination

[rightnitro]

Was just in the store, and 10% bleach gallon is up to $4.60. I added 1 of these every 2 days to keep my 13k gallon above ground at 3-4 ppm last few yrs.

Then I noticed they had a 5.5lb a "shock" powder which was 52% cal hypo. This was $20. Label on the back says add 5.2 oz (I assume daily) to chlorinate a 13k gallon pool.

So I can pay $20 to get ((5.5*16)/5.2) = 17 days of chlorination w this powder.

Or get the same 17/2 = 8.5 gallons for $39 with the 10% bleach.

Is this math right, or is the cal hypo powder dose way off?

Ok.... one half gallon of 10% LC will raise your pool's FC by ~3.5-4ppm daily.
5.2 ounces of 53% CalHypo powder will raise your FC by ~1.6 ppm daily

That's from PoolMath.

It would be about 16 to 20 Oz a day to get 4 FC and your CA would rise about 5 per day

5.5 pounds = 88 oz = 5.5 days at 16 oz a day

All chlorine prices are going up... I have been telling everyone to get a salt water generator and be happy.. The only problem with SWG is the cost is all upfront.. With Liquid chlorine and solid chlorine you pay as you go, they all cost the same in the end.. I just make mine at the pool and do not have to know or wonder where I will get the next chlorine from..

The SJ30 is about 2.5 times the size of your pool, you would only have to run your pump about 10 hours to create the chlorine you would need..

Well I'm an idiot I should have thought of it that way.

Back to The strong bleach it is.

What would raise cyanuric? Aren't bleach and cal hypo "pure" in the sense that they add no extra garbage?

Calcium, not CYA. Cal-Hypo is chlorine bound to calcium, so it adds calcium hardness to the water.

Bleach is really the only “pure” sanitizer, in that it adds nothing other than chlorine and sodium.

Not sure where you got CYA from.. The Cal-hypo will raise your CA..

Ah ok. My hardness was like 40 ppm, I've never had to worry about that. But I see your point.

If you replace a lot of your water every year, you can get away with cal-hypo for chlorination. Just keep an eye on your CA levels and your CSI.
