  • Six months is the high limit
Size: Standard
Reviews seem to be one or the other of two extremes. “My pool was green when I took the cover off.” or “My pool was crystal clear when I took the cover off.” I’m with the “It works.” crowd. I closed my above ground pool in September even though it was still warm enough to swim because I was going out of town for six weeks and I didn’t want to have to deal with it in the cold at the end of October. I followed the instructions, tossed the pill into my pool, 15X4, and put the cover on. I checked it now and then and the water continued to be clear month after month. March 12, about six months after closing the pool, we had a heck of a storm come through. Plenty of rain, but it was the wind that made the news. They said we hadn’t had winds like this for a decade. My cover came off and blew into the pool. This is one of those covers that looks more like a big round tarp with a steel cable that tightens around the side of the pool. (Thank goodness it went in the pool or it would likely have ended up in the next county.) As expected, a LOT of dirt and debris ended up in my pool. March 14 the winds had subsided and I decided I needed to get to work on the pool before all that dirt and debris becomes a permanent part of it. I took the cover out of the water and stared in dismay at all the debris in the pool. That was when I noticed it. If not for the dirt I have no doubt that the water would have been 100% clear. So that’s early September to mid March. Six months. That’s what is claimed by the product and it seems to be what I got. Except for about a three square foot section on one wall of the pool. There I saw a patch of green growth. To be fair, this is the side of the pool that gets the most sun and it has been almost exactly six months since I put the Pool Pill in the water. So, the Pool Pill advertises that it last six months. In my case, it appears that is the far limit. It’s March and I still have a lot of work cleaning out all that dirt, but the Pill does seem to have done it’s job. If I hadn’t had to close my pool early then I probably could have gone until April, but I suspect I still would have seen the beginnings of algae growth. This is the first time I’ve tried the pill and I think it did it’s job well. I didn’t quite get the full six months out of it unscathed, but I think it did a splendid job. No chemicals, except for the pill, and no running the pool filter all this time. In contrast, in the summer I run my filter 24/7 and am always vacuuming and adding chemicals yet I can still get algae blooms and I resort to shocking the water. If I wasn’t doing all this stuff all summer, what would my pool be like? Yet, the Pool Pill kept my water clear for six months all by itself with no help and no intervention from me. Next year I’ll buy two pills so I don’t have to worry as the pool closure nears six months. I’ll toss one in when I close it and toss another in four months later. I intend to close the pool in October this year, but prefer not to open it until end of April or early May. Pushing the limits of a single Pill so I’ll go with the two pill thing. If not for the wind storm I wouldn’t have all this work cleaning out my pool. Normally, to start up my pool, I just vacuum any dirt that made it’s way into the water, drop in a couple of chlorine tabs, a bag of shock and about thirty ounces of Dawn dish soap to kill any tiny wildlife that might take up residence in my pool. (The soap sticks to them and suffocates them.) Another benefit of Dawn is that it breaks the surface tension of the water so flying things like wasps can’t land on the waters surface so they don’t hang around the pool. No coming up from under water to feel a wasp sinking its stinger into your neck. I use Dawn all summer. All I know is that after using the Pool Pill for six months and doing nothing else I’m not having to scrub a pool full of algae. Having that one small patch of green algae simply tells me that six months is the high limit as far as the Pill is concerned. As far as I’m concerned, the Pool Pill worked. Just a thought: I have a couple of small waterfalls in my backyard. They can tend to grow algae pretty fast and clog things up like cholesterol in a coronary artery. I have no fish so I just add a piece of chlorine tablet to them to kill the algae. I only do it a few times in the winter but pretty much weekly in the summer. I wonder what would happen if I tossed Pool Pills into the wells. Yeah, we’re going to find out. ... show more

  • CLEAR BLUE MOMENTS AFTER OPENING!
Size: Standard
This is an AMAZING product! I was very skeptical, but now I am a believer! We bought a house with an above ground pool so pool opening and closings are totally new to us. We opened the pool a month after we moved in and it was a nightmare! We think the pool had been closed dirty, or not covered with an actual pool cover or something because it resembled a pond more than it did a pool! It took 4 weeks to get it clean and I did not want to go through that again! About a month before we closed our pool with this Winterpill, our automated robot vacuum broke. Our manual hose vac doesn't work that great so unfortunately, I was not able to get the pool 100% clean or balanced prior to closing it. I would vacuum it clean, and the next day there would be algae at the bottom. I wasn't sure why I couldn't get a handle on it, but I was sick of it and I just wanted it closed so I didn't have to vacuum it in the freezing cold anymore! The day we put the pool cover on our pool was vacuumed, but it was not crystal clear. It was milky. I can't remember if the Winterpill required 1 or 2 hole piercings, but when we opened the package we lost the little thing that is supposed to be used to pierce the ball. So, because the pool wasn't 100% perfectly clear, and the fact that I didn't know if we pierced the hole(s) too big or too small, I wasn't sure what we would find when we opened our pool. I was just hoping and praying it would be clean. I expected at least a little green, but it was actually clear blue! I couldn't believe it! These photos were taken in the moments as we were removing the cover. There were a few leaves at the bottom (maybe they were in there when we closed it and we couldn't see them because it was milky), but other than the leaves, the water was clear and blue! Our pool was closed from the end of November (we procrastinated!) and opened early May. (6 months) ... show more

  • Incredible! First time pool owner
Size: Standard
I was really skeptical of this product working on our pool after the summer we had, but the 5 star reviews do not lie. It really works as advertised! We have around a 30,000 gallon pool with a 3’ shallow end and 8’ deep end. It was our first summer to have a pool and we had a sort of freakishly rainy summer for the desert area we live in (Permian basin area of NM, close to Texas). Our pool looked more like a dang pond than a swimming pool all season long and in my inexperience with managing pool chemistry I spent around 2-4 hours a day cleaning it! Every. Single. Day! Ugh! So I was highly skeptical that I could just throw this tiny little ball of pool chemicals in and it would suffice for 6 months. We put the cover on in late October and opened it on April 2nd and this water looks amazing! It’s crystal clear all the way to the bottom and only a thin layer of silt. No algae! I included a pic with the cover on, right after we took it off, and right after I started vacuuming it so you can see how clear it was. I’ve already ordered a spring pill and a summer pill and I hope they save me a lot of hassle this swim season. Which will only be our second summer to have a pool. I spent hundreds, maybe well over a thousand dollars on pool chemicals last year because I didn’t know what I was doing. Hope these magic aqua pills do the trick for me! ... show more

  • End of Season Leftovers or poor quality product?
Size: Standard
I haven’t put them in the pool yet, but the packaging leaves something to be desired. I bought two - only one came with the instructions and neither came with the blue tool to puncture them.
