Product Description

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.

I have a Nature 2 filter with a CNA 30 cartridge. I hae been told that it has three holes that fit into the receptacle. Which replacement cartridge should I use?

A     Answered on 6/4/2018 by InyoPools Product Specialist Lennox H.

Hi, Jean. This CRA30 is the correct replacement based on the info provided. This is the only Nature 2 Cartridge ending in 30.

I am trying to replace a Nature2 cartridge which has the part number 28166. Will this cartridge, part number 28165, work for me?

A     Answered on 10/19/2014 by InyoPools Product Specialist Patrick P.

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.

Will the Nature 2 cartridge last 6 months no matter what?

A     Answered on 12/11/2012 by InyoPools Product Specialist Patrick P.

No, higher temps, 24 hour filtration and heavy bather loads will decrease the life span of the cartridge to approximately 3-5 months.

Do I still need to shock the swimming pool with a chlorine shock every week?

A     Answered on 12/11/2012 by InyoPools Product Specialist Patrick P.

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.

Are there any harmful chemicals inside of the Nature 2 cartridge? What do I do with the old one?

A     Answered on 12/10/2012 by InyoPools Product Specialist Patrick P.

There are no harmful chemicals inside of the Nature 2 cartridge. The cartridge can be thrown away with everyday household trash.

I would like to know what type of weekly maintenance (chemicals) is necessary with the Nature2 system?

A     Answered on 7/14/2006 by InyoPools Product Specialist Patrick P.

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.
