Nature 2?

[Crystal Clear Pools]

My 2 cents. I have a 36500 gallon pool with spa and waterfall. On the large size I'd say. I have salt water system, ozone a big DE filter and Nature 2. I run my filter 11 hours a day. My salt water generator keeps my chlorine at a nice 2-3 ppm. I keep my pool at a nice 85 degrees. I shock as necessary. Last year I tried not to use the nature 2 and bang I got alge. This year again I tried not to use it and bang alge again. Maybe for smaller pools its ok not to use it. But im a business guy and travel 4 days a week and dont have the time to hover over my pool. When i get home for the weekend I just want to swim and have fun. When I do use the nature 2 cylinder it allows me to turn my chlorine down to 1 ppm. I purchase my nature 2 filter at focus pools for 85 bucks. And its the big -45 unit. I've now been using nature 2 for 6 years and like it. Just my 2 cents.

I have a Nature 2 that was installed with the pool 3 years ago. I still use it. I NEVER had an algae problem with my IG 18x36. My water is pretty much crystal clear all the time. HOWEVER, I do stay on top of my pool chemistry too and don't let the chlorine levels drop as low as they say you can. So I can't sit here and say that the Nature 2 is highly recommended cuz I just don't know. I did buy 2 cartridges last year on Ebay for $75 each...

As mentioned earlier, I took my nature2 system that came with my pool to the store. They gave me a store credit that ended up paying for one Hayward filter and a float ring

couldn't be happier,

Look, for those folks who are happy with their Nature2, all power to you.

But when you tell me you couldn't control algae without your N2, it tells me you are doing something wrong, because there is NO reason not to be able to prevent algae using B-B-B, Muriatic Acid, CYA, and proper testing to correctly balance your water chemistry.

I don't know what that "something wrong" is--it could be a lot of different things, but I know it's there and sooner or later I will find it. But it's probably maintaining too low an FC for the pool.

Hmmm, the ozone is destroying the chlorine your SWG is putting in the pool and making it work harder than without the ozone to maintain the same amount of chlorine. If you turned the ozone off you would probably generate 1 ppm chlorine with your SWG output turned down and therefore prolong the life of your cell. Also, the chlorine is destroying the ozone in your generator's reaction vessel requiring you to up the ozone output. IMHO, ozone really only has benefits in a bromine system where it actually reactives the bromine bank. It just works against chlorine. The SWG by itself is more than capable of making sure your pool is ok when you are away from home (with or without the N2).

Why does ozone work against chlorine? I'm not sure I follow the logic, or the chemistry behind what you're saying.

As for Nature2, there seems to be a lot of people who are happy with the product. I think as long as that's the case I guess, it's a good product, at least to them.

The chemistry is a bit involved but they oxidize each other in a "fight to the death". If you dont believe me how about this info from the FAQ at OzoneLab instruments for starters

http://www.ozoneservices.com/faq/faq015.htm

The FAQ has quite a few intersting titbits about ozone and hydrogen peroxide in swimming pools and spas...bottom line is they no longer recommend ozone for pools and spas beecause of the problems in it's proper usuage and dosing!

As far as N2 goes, The people that are happy with their N2 most likely don't know that it is merely an erosion feeder for copper sulfate and silver nitrate and think they have a 'low chemical pool' because of the marketing hype. They are told that the pool is being sanitized naturally by "minerals". I guess you could call copper and silver minerals since they are mined from the ground (technically, their ores would be minerals!) but I don't think the copper sulfate and silver nitrate in a N2 cartridge are! Minerals is such a catchword in the industry. I had one product company Technical Rep tell me their metal remover product based on EDTA (a chlelating agent and the titrant for calcium hardness testing) would have no effect on calcium in a pool because calcium is not a metal, it's a mineral!. Last time I looked at a periodic table of the elements calcium was still a metal (in the same family as magnesium and strontium)!

[sasha]

Yeah, I guess I see your point about the hype of the word "minerals". And you're probably right about Nature2 being an erosion feeder, but I think it says on the label that it contains metallic silver, not silver nitrate.

If you read the replacement cartridge it says that copper is from copper sulfate pentahydrate and silver is from silver nitrate right on the box!. We sell the N2's in the store that I work at and have read this info right off the N2 express replacement cart. box!

Really? Then it's mislabeled...
