Hi! We are never-before pool owners in the Buffalo NY area, where it is still mostly winter until at least the middle of May, and our 30' round above ground pool was suddenly installed and filled way ahead of schedule back on April 10th. We stared at it for a week, figured out how to turn on the filter and pump three days before we unexpectedly got three more days of ice and snow, spent a lot of time on this website, joined and ordered our Tf-100 testing kit (today). We have had the filter/pump running nonstop since the snowstorm to prevent any freezing.

Now that the shock of the pool's existence has worn off and the snow has all melted, creating a muddy moat around the pool, we are ready to do something about the 21,240 gallons of water sitting in it.

A little background -- we have a large household of about a dozen people, plus many nearby relatives, and we expect pool heavy use. This pool was gifted to us by a very generous relative but we do not have any background to draw on in terms of managing it. Part of its purpose is therapeutic for a household member, so we are trying to establish it as a year-round pool by enclosing it inside an approximately 40x40 greenhouse. We hope to increase usability (early and at night, in the rain and winter), lower heating costs, avoid sunburn/sunscreen and keep the pool cleaner (with lower chemical use).

So we have long-term questions about the best, most efficient way to heat a pool in a free-standing enclosure when the average monthly temp will be near or below freezing 6 months of the year. We know farmers use large quantities of water in barrels as a heatsink to maintain greenhouse temps, so the pool itself might work in synergy with the greenhouse to mitigate the worst of the temp dips, but we will need a dedicated way to heat the pool water to swimmable temperatures and are wondering how to calculate possible solutions.

But more pressing, spring is here(-ish) and the days are warming up (occasionally) and we have immediate questions about stabilizing the pool for the moment, while the surrounding area is prepped and enclosed. It was 50 degrees earlier, it is 38 degrees right now and will be 31 overnight -- we spent all day trying to get a single pound of CYA to dissolve in a 5 gallon bucket so that we can add it to the pool without it sinking and fading/damaging the liner. We used a drill blender to dissolve, then gave it about 10 minutes for the CYA that didn't actually dissolve to settle, and dumped the CYA-water off into the pool, refilled the bucket with fresh water for the remaining granules, and repeated the blend-dump-refill process. There is still a LOT of that single pound of granules in the bottom of the bucket, and I believe 6 lbs total is called for. Is the sock method really better/safe for the liner, and more efficient? Is it maybe just too cold? Did we get a dud bag that will never dissolve? Should we just use pucks for now? We brought the bucket into the warm house for the night to see if it just needs time. Thanks for any insight on any aspect of this endeavor!

You could use pucks, so long as you are aware of exactly what ingredients they contain and what they will do. Use Pool Math's Effects of Adding section.

Personally, I use a woman's knee high pantyhose, put a pound or two in, and tie it around the middle of a pool noodle. Throw that sucker in the pool and ignore it for a while. The noodle keeps the sock away from the liner. In a day, go back out and give the sock a few squeezes. You can squeeze it all out in 15-30 minutes if you're in a rush and your hands can stand the cold water, or you can just keep going back in an hour or a day and give another squeeze. It will all come out eventually.

I see that you have already created your signature and gotten your test kit. Great job with those. Have you started testing your water yet? How's that going? Any questions, ask away.

Thank you for the pool noodle idea, that does seem pretty safe and we will try it tomorrow! We are just waiting for our good test kit to arrive, but we did get little strips with the pool that said our ph/alkalinity was good (yay) but CYA and Chlorines were 0, which we expected from pool school. I know they are not the best, but since the pool is filled with tap water from our hose at the moment, that all seems normal. We have liquid bleach on hand 12.5%, but my understanding is that it can't last if we don't get the CYA up first, so that is our goal, then add the chlorine in a couple days when we are sure the CYA readings are good. Thanks again for the suggestions and help!
 
If you want to run your pool year round in an unheated space, you will need a heater. A gas heater. A greenhouse will not get warm enough to warm the water to a temp you will want to swim in. How warm did you want the water? "Cold" water is typically mid-70s and usually what athletes train in. A typical pool temp that is comfortable is around 88 degrees, which is skin temperature.

For CYA dissolving in a bucket could take a while. I would say put the CYA in a skimmer sock, put it in the bucket, leave it for 30 minutes, then see how much of it you can squeeze out. Do that until no more squeezes out, dump what you got in the bucket into the pool, and refill the bucket for more squeezing. What is your chlorine level? I assume you are manually chlorinating? What is the current water temp? If you hit 60, start chlorinating or else you'll end up with algae.
 
You should also go through some of the ABC’s.


If you really plan to use it year round, I’d also plan on a salt water chlorine generator. Sanitizer (ie chlorine) will need to be added daily year round. Heading out in snow to add chlorine even to a greenhouse won’t be fun every day. I’d stay away from the pucks.

I also remember someone in this site doing something similar (can’t remember the thread) and they had to do something about the condensation and chloramine vapor build up in an enclosed space. You’ll likely need some venting in the greenhouse for that.

You can take a look at this system here.
I only had 1 when I had a above ground pool and it did the job. I had on top only garage (next to the pool) and ran pvc piping to pump. Simple installation and it doesn't have to be on a roof. As long as is facing the sun. 10 degrees up all the time and use solar blanket for the night.

Thank you, I will look into the salt-water system, which I have not considered before. I am going through all of the pool school material too, which has helped a lot.

Thanks for this recommendation, it looks very doable.
