Nature2 Express Mineral Purifier Replacement Cartridges

So how can I claim that spending money on this cartridge will save you money? I have to explain some history...We had our ingound pool built 8 years ago. The builder insisted that we add the Nature2 cartridge into our system. He claimed it was well worth the annual expense. He told me to replace it every six months (I live in Texas where it can get warm all year around) and I would expect to spend less on chemicals.Well that first year, I decided I would wait until the following summer to replace. No problem. Everything was clear and clean. However, after a couple of years I thought I might be spending money I didn't need to and skipped buying it for that summer. What a mistake. My pool was constantly out of balance. I was spending over $100 a month on chemicals I had never needed before. This is on top of the usual cost of chemicals such as chlorine that I was expecting to spend. By the time that summer was over, I had spent over $600 more than I would have otherwise.For the last 6 years, I have faithfully added a refreshed cartridge and reaped the rewards. I rarely add any chemicals besides my chlorine tabs. My pool has been tested every two weeks, and the techs can find nothing wrong with it. My semi-scientific cause and effect research leads me to believe the Nature2 is the reason my pool looks great and my chemical needs are lower.

False packing... it shows a see through lens on the box. In years past it was that way with the see through lens. Change your box! If it holds up to the summer without issues I'll update this with 4 stars.

Our pool requires the unit; pool operates beautifully and is always clean and clear. My amazon review focuses on the price. The local store sells these for $55 higher than the amazon price. Even with s/h this was a much better deal than anything we could find locally in Texas. And, it came w/in days of ordering. Highly recommend and will be ordering replacement units here again.

clean blue pool so far. wish the pool place had of told me about this!second year of using this I would highly recommend you try it saves a lot of work!!!!!

I have had a Nature2 for many years to help with my swimming pool water staying clear without the need for high chlorine. This replacement is probably the 20th one I have had and I will keep getting them.

Fits great and works great. We live so far away from a pool supplier. Very happy Amazon carries products like this.

Right product, on time delivery, good price.

This always me to maintain a better PH level in the pool with fewer chemicals being added. I do recommend using the Nature 2 cartridge.
