Pool RX 102001 6 Month Swimming Pool Algaecide Replacement, Single Unit, Blue

I have had pools since 1996. We have currently owned this house and pool since 2006. In Houston, Tx we get brutally hot summers and ridiculous humidity. Every pool I have had from May to Sept we battle weekly green algae. Even having pool companies come once a week we still battled algae in the summer months. I decided to try this last fall and was very pleased. Couldn't wait to see what it would do in the summer months. It said to replace every 6-12 months. I think 3-6 was more ideal. Again...I say this because our water gets so hot especially when it's 110 outside.Basically the short of it is : this product does exactly what it says it will do. It does make your pool bluer, more so the first month of use. But never have I ever NOT had green algae start to grow until I started using this. I have had NO ALGAE at all this summer. The first time in 25 years. (Mind you I have had three different pools with different colored plaster. White, dark blue and tinted blue as in this picture) I have minimized my chemical usage as well. I am not having to fill the pool full of shock or an overabundance of chlorine to keep the algae away. The water smells better and even feels better! Now if only it could make the water cooler during these hot days, I would be totally impressed! ha!I would highly recommend this product. I got rid of my pool company three years ago and have been having to do all the work ourselves and this had reduced my stress about my pool chemicals and cleaning. I am very impressed and already bought my next one for the change. You cannot go wrong with this product.

I don’t want to even think about how much less money I would have spent over the last decade if I’d found this magic product when we first moved into our home with a 40,000 gallon pool. I live in a very hot region of the country on a wooded lot. It felt like I was spending as much time fighting algae as I was enjoying our pool. I can’t recall how I stumbled on this, but I ordered it and it sat on my counter for about a week. Then my salt cell chlorine generator died. Luckily, the pool was nice and clear when the cell failed. I dropped this baby into the filter basket (along with a booster pack as recommended for a pool that size) somewhat as a Hail Mary just hopeful that it along with some added chlorine would avert a mess of algae. Well, I only THOUGHT my pool water was clear, because I woke up the next morning to the most beautiful, crystal clear water imaginable — and lines of dead algae on the bottom. This was about 6 weeks ago. I’ve added about 3 gallons of liquid chlorine total in our 40,000 gallon pool since then - probably could’ve gotten away with even less, but we’ve had a ton of rain and yard debris from redoing landscaping. That’s all. It’s still perfect. I don’t recall how it works, but it does. We also noticed today that the water doesn’t burn our eyes at all. It still has salt in it, but just seems perfect. No red or burning eyes. Water feels better than ever, too. I’ve planned to replace the salt water chlorine generator, but at over $1500 plus installation, and with a clear pool, I haven’t been convinced to go that route again.So “clearly” I highly recommend this product.

I started using this last summer when I was constantly fighting algae. I was scrubbing the pool daily to keep the algae down. After one final major shock and scrub I added the plastic unit to my strainer basket. I really didn’t have high expectations but my neighbor recommended it. Well it worked amazingly well and I had no problems with algae the rest of the summer. A new unit was the first thing I added in the spring and there hasn’t been any algae this year.

It’s never happened since we put the pool in over 25 years ago, we are still using the pool in October because of the blistering heat of summer will not let go here in Phoenix. Forecasting 101 today and it’s the 8th of the month!Which brings me to this product. We use it every year and have never had a major algae attack on the pool. Because the season continues I ordered this product to pep up the one we put in in May.I ran the pump during the heat of the day per the instructions for 8 hours. The next morning the pool is sparkling like I had added clarifier. Although we have a weekly pool service we keep our pool immaculate and it makes going in the water a lot more pleasant. Our pool water gets into the 90’s during the summer months so becomes an easy target for algae of all sorts. This product really does the job it says it does and it could not be easier to use. Just drop it in your skimmer basket and forget it for 4-5 months.
