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.

What is the difference between the nature 2 pro g plus 1/g G25 (w26725) n the nature 2 pro g series crg 25 (w26725) besides the price?

These two items would be the exact same so I would go with the one that is less expensive.

Will this cartridge replace my W28125

Terry- The CRG25 Nature2 G Series Replacement Cartridge 25K (W26725) is interchangeable with the W28125.

(5 out of 5 stars) Nature 2 G Series
Reviewed By: Brian C. from lewisville, NC ()
Pros: Works and no further maintenance required once it's charged
Cons: There are none
Have used Nature 2 G series replacement cartridges for many years. It's the only way to maintain a very low cost trouble free swim season. It allows you to reduce the amount of chlorine used and even with the very hot summer we've had in North Carolina this year I have never had a problem with algae. I highly recommend to product to any pool owner.

(5 out of 5 stars) Great cartridge, identical to original
Reviewed By: APBJ from Denton, TX ()
Pros: Great product, smooth transaction
Cons: Price
Product was identical to the original. I ordered this cartridge from INYO only because I was ordering other, more expensive items from them. INYO's price was higher than competitors' by 15%, but I was willing to pay for the convenience.

(5 out of 5 stars) Fantastic Water Cleaner
Reviewed By: Big ED from N. Royalton, Ohio ()
Pros: Saves money & is a great way to clean water.
Cons: None
I have been using this Nature2 Cartridge for several years and it has reduced the amount of chlorine usage I use in a season by 80%. It forms copper and aluminum ions that attacks bacteria. WIth the low level of chlorine it requires it is painless to open up your eyes under the water. INYO Pool has this cartridge at one of the most lowest prices and has a history of satisfying its customers with good product & good service.
