Nature2 Mineral Cartridge Replacement A30

Great product !Have used for,about 25 years

As promised and quality product

I have used this product for more than 20 years and am very satisfied as it allows me to swim in water with minimum chlorine.

We have used the Nature2 system on our pool for over 5 years now and every year, our pool has been crystal clear with low chlorine levels. It really is amazing how well this little cartridge works on such a large pool. I would prefer this over huge amounts of chlorine any day. Now I would like to note that this particular model is NOT designed for the Nature2 A type "Limited" systems, but it can be easily modified to work. I think that the pool stores sell the limited to keep business, but really the only change is a third hole in the bottom of the cartridge. So if your pool store is closing (like ours) or is a rip off (like ours), then I would recommend buying this and modifying as needed. All you need to do is either drill a hole where it is marked on the cartridge (already has the outline for it) or take a flat head screwdriver to pry off the yellow plate on the bottom and replace it with the plate from an old cartridge, which is what we did and it only took about 10 seconds of forceful prying. It does not affect the performance of the cartridge at all since the water flow goes through the center. Hopefully this helps! And if you have never used the Nature2 system, I highly recommend it! One star docked for not selling the limited model though...

Great price! Used this mineral filter for 14 years. If i purchase at the local pool stores they are 100.00. Buy online and they are only 70.00

Wonderful have had for year makes a great difference in chlorine needs

We have an old system we bought at The Great Escape over 15 years ago. It fit perfectly right into the 3 holes.

I bought the Nature2 system when i purchased my pool. I used it every season for seven years. I always thought that my pool water was crystal clear because I took better pride in keeping my water balanced and pool cleaner than my neighbors. Even through strings of 90+ days my water was clear with no signs of algae even though my chlorine levels were low. Then I decided to try a summer without Nature2. The first season was great. Although I used a lot more chlorine than other years it seemed that I was saving money. The second year was terrible. During the hottest part of the summer my pool turned green almost overnight, even though I super chlorinated to try to head it off. After a week of continuous vacuuming, super chlorinating and balancing, the pool was still green. I started dumping in algaecide which cleared the pool temporarily. The short of it is, after about a three week battle and about $100 of chlorine and algaecide my pool finally cleared. I believe that my first season without Nature2 was successful because the pool water still contained some of the treatment from years of Nature2 use. The second year the pool developed a leak and I need to replace about half the water. Between the leak and heavy rains the pool was doomed. I'm back to using Nature2. The cartridge more than pays for itself in chemicals, work, and usability of the pool. I can't recommend this product highly enough.
