a question for the "puck gurus"

[let_her_flicker]

Do not leave pucks in your skimmer with pump shut off. The pucks will still dissolve in the water and highly chlorinated water will be in the skimmer now. If some of that water leeches out around the mouth of the skimmer you risk bleaching your liner around the skimmer.

If you have an old, faded liner or don't care if it gets damaged you can leave them in. Personally, I would not do that.

Sevver,

You're CYA level will remain pretty constant....probably 'til next Spring.

Flicker,

back to my original question. When you remove them, how do you store them 'til the pump is restarted?

Dave,

Sorry, I didn't answer your question. I always ran my pump full time when using pucks. I would place the skimmer basket (with pucks) on my plastic top rail if I added bleach (to shock) in the skimmer, and then replaced the basket.

I would assume some dissolving would still occur since the puck is wet. Maybe try putting one in a sealed sandwich bag. If it dissolves you will see it. Secondly, if chlorine gas builds up in the bag it will expand. Just an idea. That is if you are talking about one puck at a time.

When I first joined the forum (about 5 yrs. ago) I asked Ben how much CYA a puck would add to a 16,000 gallone pool and he said "about 1 ppm."

Dave, thanks for posting your #s . I've always told my customers to just pull them out and put them on a plastic lid from one of their old buckets - it saves the deck from bleaching and keeps the tabs close to the skimmer for reinstallation the next day.
(Don't want to start a huge debate but; why do you want to raise the cya?)

I would agree with other posters - just put the pucks on a dry surface (away from children's reach, or animal's reach).

Don't put them in a closed container - I'm pretty sure that once they are wet, they will continue to react with the water and gasses may build up in a close container and possible lead to the container rupturing.

I also think you are about right on the CYA level's for your pool size. I'm back on tabs this year - 2 months so far and no problems. CYA is still in a reasonable range. I usually have to pump enough water out over the winter months that I'm changing out about 1/2 of my water every year. The tabs in my online feeder do a fine job for me

Good luck

Hi, Ted,

(

I seem to lose about 4ppm each day in this pool (absolute full Sun....I think I might even get some at night!)

I'll be curious to see if I can cut that loss back by going to 50CYA....maybe even 60. I lose it every winter, anyway.

Dave, hi, you know what you're doing, so I won't question it further.

Dave,
Yeah, floaters are cheap--an adjustable one is $10-$15. Get one. I don't advise handling wet pucks. The fumes and the acidity could hurt you. With a floater, you can lift the WHOLE thing out, but have a safe place to put it as it can bleach a circle on your deck!
