## Customer Reviews

### ⭐⭐⭐⭐⭐ Return user of the Nature2 Cartridge.
*by A***H on June 2, 2011*

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.

### ⭐⭐⭐⭐⭐ Awesome
*by N***L on May 31, 2024*

The extra boost your filter needs for sparkling water everyday. Low chlorine usage, silver and copper natural disinfectants, been using for years and never an algae issue😎

### ⭐⭐⭐⭐⭐ This seems to be a replacement also for W29035
*by M***8 on June 30, 2019*

My system "Calritec" that required a CRM25 cartige (or W29035). I could fit it in the holder, the two square holders and the connection seems the same. I replace it and it works. Someone with the same problem (the W29035 cost 150 with shipping) might find this interesting. On the label it says for pools 10,000 to 30,000 Gallons, just so you need to make your calculation. Mine is 25,000 so it should work, maybe will not last as long, will see.
