Nature2 Replacement Cartridge for the CRA30 Above Ground Pool System.
Pool water purified by Nature2 actually exceeds EPA drinking water standards for bacteria. Imagine, the water in your swimming pool may well be cleaner than the water you drink. When you swim in a pool that's been purified by Nature2, you will enjoy pool water that is actually softer and purer than you've ever experienced in any pool. Your hair and skin will feel incredible compared to swimming in chemically-overloaded water.
For all above ground pools from 5,000 - 30,000 gals.
6 Month Cartridge
I would like to know what type of weekly maintenance (chemicals) is necessary with the Nature2 system?
Reply
With the Nature2 you would maintain your pool the same way as if you did not have Nature2. The only thing that will change is that you will maintain a lower chlorine residual with the Nature2. Instead of maintaining a chlorine residual of 3.0, you would maintain a chlorine residual of 1.5 with Nature2. This results in using approximately 50% less chlorine.

Are there any harmful chemicals inside of the Nature 2 cartridge? What do I do with the old one?
Reply
There are no harmful chemicals inside of the Nature 2 cartridge. The cartridge can be thrown away with everyday household trash.

Do I still need to shock the swimming pool with a chlorine shock every week?
Reply
No, you will need a chlorine shock at first to activate the Nature 2 cell. After that, you can use a non-chlorine shock for weekly shocking.

Will the Nature 2 cartridge last 6 months no matter what?
Reply
No, higher temps, 24 hour filtration and heavy bather loads will decrease the life span of the cartridge to approximately 3-5 months.

I am trying to replace a Nature2 cartridge which has the part number 28166. Will this cartridge, part number 28165, work for me?
Reply
The W28166 is specifically designed to work on the Nature Limited CRA30 the W28166 has 3 female ports on it so it can fit the Limited vessel. The W28165 does not have these female ports on the cartridge so it will not fit the Limited vessel. Since you have the Limited vessel you will require the purchase of the W28166 and the W28165 will not work in your system.

(5 out of 5 stars) Nature2 + tiny amt chlorine = sparkling H2O
Reviewed By: Corey C. from Attleboro, MA ()
Have been using these cartridges to sanitize my pool for about 5 years now. Pool stays sparkling clear, even through the fall/winter/spring. No shock when I take the cover off. I just swap out the cartridge and add a small (0.5-1.0 ppm) and that's it. At ~$100.00 I don't see this as an expensive alternative. Between the consistent results and the reduction in pool chemicals it seems a wash to me. It also allows me to keep the water in the pool very soft. Not sure if this is typical, but it works for me.

Pros: not messy
The nature 2 cartridge seems to keep down my chlorine level good. I have to use a floating chlorinator but still do not have to use as much chlorine tablets as i would if i did not have the nature 2 cartridge
