CYA in a sock

[aylad]

Putting CYA in a sock is a recommendation that we've been making on this forum for years, even before the other forum that you're alluding to ever existed. We do not recommend it as the sole way to add CYA; however, most of the people we have this discussion with are also having filter issues, and that's why the sock is being recommended. We may have gotten lazy about pointing out the other methods, but I remember as many posts instructing people to put it into the skimmer and not backwash for a week as I do about putting it into the sock.

Many of the labels on CYA containers (at least around here) instruct users to broadcast it directly into the pool. Personally, I have a problem with this method. I also hesitate these days to have people put it into the skimmer if I'm not positive that they'll dilute it first--I have firsthand knowledge of a pool where too much CYA was put into the skimmer all at one time and it formed a plug in the pipes, resulting in broken pipes and concrete replacement. So...I'm not sure what about this is bothering you, but CYA in a sock is a perfectly reasonable way to get it into the pool. Not because it's the only way, but because it's really the easiest.

EXACTLY! It's from this forum the use of a sock was taken (we had QUITE a discussion about it over there!) and then made into the ONLY correct way to do it. I am just saying that, unless you ARE having filter problems, it is entirely unnecessary!

I think I read a post about liquid CYA being available now...? To me, that's the easiest I recall something about it being more expensive though...

QUITE a bit more expensive in fact.
1 gallon Liquid Conditioner raises 10000 gallons about 35 ppm and costs close to $30 online.
2.75 lbs CYA raises 10000 gallons about 35 ppm, 4 lbs costs between abut $10 and $20 online.

do the math

Wow, that is pricey... Does it still take a week or so to start working/showing? If it starts right away, it might save some money in bleach...

It is supposed to work my faster BUT if you filter 24/7 for a day or two after adding CYA it starts showing up pretty quick, at least enough to protect the chlorine.

Polyvue,
A couple months ago I tried dissolving a couple cups of CYA granules in a gallon jug. Nope. Some did, most didn't. Kept pouring off the concentrated liquid into the skimmer and refilling and eventually after a couple weeks the solid was almost dissolved. Certainly didn't dissolve in 10 minutes. The granules are fine enough they will easily, or quickly, get past the skimmer and pump baskets. Once they make it to the filter how do you know how long they take to dissolve? I don't use the stuff personally. I smash up pucks.
