How To Add CYA to Your Pool

Adding cyanuric acid or CYA to your pool using a skimmer sock in the skimmer.

[@Steve-vd3nx]

This worked perfectly with skimmer sock, thank you my man. Only thing I would change is possibly giving it another 30 minutes of sitting there before massaging bag. The CYA crystals will dissolve even more.

[@WoodBob]

Thanks for the comment. I have noticed there are different types of granular CYA some of which takes longer than others to dissolve.

[@gregcostello1847]

I did this just now with just 1 lb. tied up in a sock. I came by after an hour expecting to massage it, and every speck of CYA was gone!

[@giselefriend7696]

Thank you so much! This way works perfectly!!!

[@wolflordbanner4429]

Thanks😊 for the video.very helpfup

[@kyllieendsley3861]

I did cya last night and shock and tablet

[@bhasins]

Great video. Why not just pre-mix the CYA in water and pour into the skimmer?

[@WoodBob]

The best I could mix it in would be a 5 gallon bucket. I am not sure the super-saturation level but mixing 5lbs of CYA in 5 gallons would make a pretty strong mixture, if it mixed 100%. As you saw it takes under 10 minutes to dissolve after a 30 minute soak. I can't imagine it being much easier/quicker than that!

Very simple, because it takes forever. I tried doing this with a 5-pound bucket and hot water and I had to stir and stir and stir her for hours.

[@scotty.1649]

It's not necessary to spend any time whatsoever massaging the bag. Justvputvthe bag in the skimmer and forget about it. CYA will dissolve in a few days.

[@WoodBob]

That's the whole point though, I don't want to wait a few days. I can raise my CYA in a couple hours with this method.

[@facebookmakesmesick]

Holy sit just dis this with sock but over returns or ported or whatever they are called it went through sock like powder in like 35 minutes...I used 5o put it in deep end and it would sit there for 3 days and I'd brush it back and forth with brush non stop...

[@DrewMIATL]

Just pour it in the skimmer slowly, or pour it in the pump basket and call it a day

[@WoodBob]

That method tends to result in CYA being stuck in the filter. It does not always 100% dissolve. For those that backwash, it can result in lost CYA as well. With my method, you will have a fully dissolved CYA addition with accurate testing within hours.

[@DrewMIATL]

@@WoodBob I can definitely see that being true. I just was going by what my job said to do. What about the pump basket? Most of my pools are cartridge filters.

[@NP-gb5su]

I keep adding stabilizer to my pool (perfect alkalinity, ph and chlorine) but CYA reading always says 0. I even poured a pound of stabilizer in a bucket and tested that water after mixing for 10 minutes. Test strips showed no CYA in the bucket.. I am confused, can some stabilizers not influence CYA testing? My test strips and stabilizer are both new..

[@WoodBob]

CYA never leaves the water. It does degrade over time. But, there is a certain type of bacteria that can consume it. A byproduct of that is ammonia. You can test your water for ammonia using an aquarium test kit. Any ammonia reading at all is bad. Ammonia will be neutralized by chlorine very quickly. So if your pool can hold chlorine, then it is not likely CYA eating bacteria. Another possibility is that you have calcium chloride instead of CYA. They look similar. You could try mixing some of what you have in a small bucket. If the water in the bucking gets warm, it is calcium. Careful the water can actually get hot enough to burn you. What are you using to test CYA? Test strips are not to be trusted so if you are using them, I suggest tossing them in the trash where they belong and purchasing a quality Taylor pool test kit. Good luck!

[@drdrew3]

You need to look at the fine print on the container for the stabilizer. Make sure it specifically lists cyanuric acid as the main active ingredient. It should be extremely easy to achieve CYA levels in your pool and even easier in just a bucket. Either something wrong with the added chemical or something wrong with your test method. Read the fine print on test strips and make sure you follow instructions exactly and read from the correct row. Would be much better to switch to dropper kit if you are getting serious about proper pool chemistry

[@johnfink9020]

My Aquacheck 7 strips have never been off. Cheaper to buy a case of those. 6 bottles of 100 strips. Thats 600 strips for way cheaper than the Taylor. Plus no mixing and buying reagents.

[@christ6370]

Is it just me or is the sound timing way off. Why don't you use the usual 20-50ppm CYA recommendations so you don't block your chlorine? Why do you have to add CYA every year? Which types of sanitizers do you use? Im always fighting raising CYA because of my Tri-chlor tablet use, they are 50% CYA. Thanks

[@WoodBob]

My pool is saltwater and the recommended minimum amount of CYA for a saltwater pool is 70ppm. So being saltwater my sanitizer is chlorine. I add around 10lbs every other year to make up for degraded CYA. I keep my pool very warm sometimes 95. Warmer water makes CYA degrade faster.

[@Peter-Alexander]

My swg manual advises a maximum of 30. Personally I don't see why you would need a higher CYA value than 20 to 30. It is really sufficient to protect against UV and chlorine stays more effective at these lower values.

[@tcudahey9550]

Thanks for the video. Very informative. Why do you keep mis-pronouncing cyanuric acid?…LOL😂 It’s ‘sigh a noor ick.’

[@WoodBob]

LOL - Thanks I will correct for future videos!

[@wildwoodtop]

Dude where did you get that bag That thing is awesome! is that your old lady' stocking lol

[@stevenorris2731]

I simply use an old pair of panty hose or knee high stockings. They work perfectly.

[@johnfink9020]

They are skimmer socks. A pool store will know what youre talking about.

[@froggishleap]

Can this same method be used for stabilizer?

[@closewatcher8586]

CYA is stabilizer.

[@froggishleap]

@closewatcher8586 ok thanks I thought it was a stabilizer reducer.

[@monicarowe7915]

Sorry, but I wouldn’t be handling that chemical as you demonstrate, very clearly, in your video- It’s a well-known irritant!

[@carnagejlu]

Do it all the time. No issue.
