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.

I usually use the Nature 2 G series cartridge which is much taller. Will the Nature 2 M series work in my container?

A  Answered on 8/1/2012 by InyoPools Product Specialist Patrick P.

No the Nature 2 M Series cartridge will not work as a replacement for the Nature 2 G Series Cartridge. We do sell the Nature 2 G Series cartridge here http://www.inyopools.com/sanitizers_nature2.aspx listed as CRG25, CRG35 or CRG45.

Is this the same part as the N2CM/W28155 cartridge?

A  Answered on 12/1/2014 by InyoPools Product Specialist Robert M.

Hello Mark - The 2CM25 is the same as the Zodiac W28155.

The current cartridge I am using for my Vision Nature2 purifier is "W28165". Will this cartridge #W28155 work in my unit?

A  Answered on 4/1/2015 by InyoPools Product Specialist Lennox H.

Tom, the W28165 is for an above ground pool system. The W28155 will not fit because the W28165 is for the CRA Series and the W28155 the CRM Series.

Can the nature 2 be used with a salt generator, is it compatible with saltwater?

Hi Mike, You can use a Nature2 Mineral Sanitizer on a salt water pool.
