My pool, "The Bleach Beast"

[vanhout]

With 17,280 gallons, 3 quarts is 2.6 ppm per day of Cl lost. I lose 2 - 3 ppm per day from my pool, and it's 36,000 gallons, so that's one big jug of Cl (1.42 gallons) per day...

I read someone else posted on here the other day that they thought 2 ppm per day was normal.

You might try raising your CYA a little and see if that slows your chlorine consumption.

One thought--when you finished your Baq conversion, did you change your filter media? If not, you probably still have Baq gunk in the filter...

Thank you all for your replies. I bought a new sand filter that only ran on baquabeast for a 3 days. It was then drained and has ran on bleach since.

It is reassuring that it is normal to lose 2-3 ppm of FC a day. That makes sense when I look at my logbook. Most of my loss is during the day and is around 2 ppm.

It just seems like I have to keep a lot of bleach around, 4 bottles to shock when I am above .5 CC and then 1 per day to keep my 3-6 ppm level. I am not using and cal-hypo pucks or granules because I want to keep control of my stablizer.

Is there a non-stabilized option that will add FC without CYA? If so, would it make a cost/storage difference or even add enough FC to keep it about 3 pmm for a day or two? Any ideas?

Absolutely. With your low calcium levels, you can use granular Cal Hypo on a daily basis.

Your test results appear very precise...that's good. I would suggest the use of Cal Hypo and test the Ca level about once per week....it'll slowly climb. There's a pretty wide range of acceptable Ca limits (somewhere around none to maybe 500) so, once the Ca tested about 300, I would stop and switch back to bleach. That may be all Summer in your pool.

Granular Cal Hypo is a good shock source as well.

So that sand was in during the conversion?

Folks please correct me if I'm wrong, but doesn't the CL cause the BAQ to perciptate out of solution and get caught by the filter? That's why it's important to change sand *after* the conversion?

Yes, that's my understanding too. If it were my pool I would change the sand again.....and I'll bet that your consumption will drop, too.

I ran the baq water in the new sand filter for 2.5 days. I hadn't decided to switch yet and was not enlightened by this forum yet. I really don't want to change my sand. The water is crystal clear and I would rather spend the money on bleach.
Will the baq precipitate out over time?

probably not, but if your pool is clear and you can live with the bleach consumption, then happy swimming!!
