Smart Sticks, Bioguard

Postby rat407 » Sat 23 Jun, 2007 12:15

Does using Smart Sticks put CYA in the pool? I'm trying to learn what I can and have been reading this forum and ThePoolForum for the past 5 hours and few days as well.
I figure it is time to educate myself and do this right instead of expecting the local pool store, (who can't keep an employee for more than a month) tell me what is best for my pool.

My CYA is at 100 in a 24k gallon pool. I figure the best bet is to do a partial drain and fill. Exactly how much do I take out of the pool? It is a 36'x18'.

Thanks

Yes, they sure do.

The volume of water you need to replace depends on what number you are trying to get down to.


If you are at 100 and trying to get down to 50 you need to dump half your water.

Are the sticks worth using then? Are there any out there that do not add CYA?

I don't think there is a stick or a tablet available that does not add CYA.

They are fine to use for special situations:
If you drain your pool at the end of the swimming season.
If you are away on vacation.
If your CYA is low.
If you have enough splash out and replacement of water to keep your level low, or do partial drain/replacements regularly on your pool.

There are some slow-dissolving tablets of Cal-Hypo that are put into the skimmer, but they tend to fall apart and leave some residue -- they aren't as slow-dissolving as Trichlor. At least they don't add CYA, but they do increase CH, but on a percentage basis only around 1/10th as much. For every 1 ppm FC added by Trichlor, you get 0.6 ppm CYA so out of 30 ppm CYA that's an increase of 2%. For every 1 ppm FC added by Cal-Hypo, you get 0.7 ppm CH so out of 300 ppm CH that's an increase of about 0.2%.

Dang, I always tend to forget about Cal Hypo tablets, Richard.

I have such a naturally high Calcium in my fill water, I often forget about them.
