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.
The current cartridge I am using for my Vision Nature2 purifier is "W28165". Will this cartridge #W28155 work in my unit?
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.
Is this the same part as the N2CM/W28155 cartridge?
Hello Mark - The 2CM25 is the same as the Zodiac W28155.
I usually use the Nature 2 G series cartridge which is much taller. Will the Nature 2 M series work in my container?
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.
I would like to know what type of weekly maintenance (chemicals) is necessary with the Nature2 system?
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.

Pros: Keeps pool perfect....with fewer chemicals, or chemical adjustments needed!
Cons: Be sure to have pool water balanced before adding new cartridge....it will be much more efficient if you do!
We have always used this filter. Early this spring, we needed to replace it and put off getting a replacement for several months....bad idea! We have had to add more chemicals to our pool this year than we ever have! Once we got the pool balanced again, we put in our new cartridge and, whew!...haven't been having to add near the chemicals to keep that "perfect" water! I highly recommend this filter system and the cartridges.

Pros: Easy twice a year replacement.
This cartridge works in my Visions Filtration System. It allows me to keep the pool sanitized without a high level of chlorine. In fact, the chlorine content of my pool is at a lower level than the water I get from my tap. And that water is very good.

Pros: very easy to use and less expensive than other chemicals.
Cons: Have not found any.
This filter is used with Nature 2 systems and is one of the best cleaning systems I have found during my 33 years as a pool owner. Before nature 2 I used to have an every summer battle with green algie. Since switching to this product approximately 10 years ago I have not had any problem with algie. It is so much easier than having to keep chlorine levels adjusted and measured each week.

Pros: no weekly chlorine hassle
Cons: if forget to check on the cartridge you run out of chlorine without knowing.
Nice to purchase online. Cheaper and less hassle. Auto chlorine is easier, you use less chlorine and there is less chance of problems such as algae due to forgetting your chlorine. Just have to replace once per month - about.

Pros: Replaces the need for over treating with chemicals.
Cons: Hard to come by at local pool supply stores
We've used this filter in our pool for years and it's makes such a difference in using chemicals in large amounts. It's such a good feeling not to have all those chemical affects on your skin and hair.
