Tricks for dissolving CYA

[Quickstep192]

Anybody have any tricks for dissolving CYA?

I usually have to add a bunch at startup after adding make up water.

I’ve tried putting the CYA In a mesh bag and either hanging in front of the skimmer, or in the skimmer. It still takes weeks to dissolve. Meanwhile, my CYA is low and the sun is coming for my chlorine.

I’ve tried adding boiling water to the CYA in a bucket; that helps, but once the water cools off is back to slowville.

Do you guys have any tricks?

Time. Walk away and let it soak.

I open with cold water and evenso, the next day the CYA squishes right out. Mid season it needs 30 mins.

What are you doing to dissolve it? Mesh bag, panty hose, sock?

I have a large pool and need big doses so I tie it up in a Tshirt instead of several socks.

I make a pile on the chest of the shirt and fold the sides up into a sack and then tie off the top. Then I hang that in front of a return and walk away from it.

QS,

I assume that is a little bit of sarcasm

My CYA is gone in a few hours...

1. I put the CYA into a women's knee high stocking.
2. I then use the neck of the stocking to hang the stocking over an operating pool return.
3. I come back in an hour or so and squeeze the stocking while in the water. This produce a large cloud of CYA..
4. I come back in an hour or so and do it again, and repeat.
5. 95% of the CYA is gone with in half a day or less.
6. I throw the stocking away..

Note.. If you don't squeeze, it seems the CYA forms a crust that prevents the CYA from escaping the stocking.

Thanks,

I use a skimmer sock. I fit the sock in the skimmer and then add the CYA (typically 8 oz at a time). Leave the pump running and a few hours later it is gone.

I found out this year that not all 100% cya dissolves the same for some reason. I had two 3lb socks each with different cya. One was from home depot and the other was from in the swim. The one from home depot would squish out in no time and the one from in the Swin never did. It ended up taking 3 days to dissolve.

I even switched which skimmers they were in and it made no difference. I don't understand what the difference is as they both looked the same amd were 100% but for some reason not all go squishy.

I use old pair of panty hose, set it inside a leaf net with pole attached. Kinda balance the pole so it doesn’t fall in, get the net in front of a return, but not against the vinyl. Leave it be, squish it, leave it be, squish it….repeat. If I’m in a hurry I’ll sit on the side of the pool and squish longer….

I had 2 small bags with the same brand CYA, from the same pallet, respond differently. One mushed right out and one took 2 days. All I can speculate is some moisture got in the difficult bag and it firmed it up.

Mesh brew bag from Amazon. Doesn’t take very long.

Ok. All you hot climate people. Try it in January, then report back. That's what it's like for us opening up north.

Your pool looks just like mine, except I do not have a spa, and where you have trees I have neighbors...

Very nice looking pool.

Thanks for sharing and making me feel jealous..

I started with a sock and found it was taking a long time to dissolve, and squeezing it out was difficult. I switched to using knee highs and the process is much easier for me.

I use a long sock and fill it with the amount I need. I get it all as wet as I can squeezing it in the pool then anchor it with a rock and let it hang over a return for a couple hours. Some dissolves but mostly it get soupy so that I can squeeze the sock over and over. I walk around to different returns squeezing at each one then it’s mostly all done. First dose of the season takes the most time but gradual changes whenever needed during the season is much quicker.
