Nature Two Pool System Versus Salt System

[BigDave]

Thanks Ben (I should have looked it up) now I do know what a Fusion Nature Two is.

billie:
I still think SWCG is a better choice. Trichlor can be a valid choice for chlorination but can't be used as the only source of chlorine. It adds stabilizer as well as chlorine which is good to a point but as stabilizer level increases so does the required level of chlorine necessary to sanitize. Trichlor also tends to push pH down which would have to be brought up.

Copper can kill algae and silver can slowly kill some (not all) harmful bacteria. The Nature 2 system still requires chlorine for sanitization and oxidisation of stuff that gets in / is left in the pool. Silver and copper can stain pools and swimmers (copper makes fingernails and blonde hair turn green).

I don't believe that it would be possible to maintain extremely low chlorine levels with the trichlor feeder continuously increasing the stabilizer level. And since you'll need to chlorinate the pool anyway, I can't see how buying the copper / silver cartridges could save any money.

Both copper and silver have very slow kill times so they do NOT allow you to run lower chlorine levels than without them. Copper and silver can both stain pools and copper is what turns hair green. Period!
The Nature 2 'mineral' cartridges have to be replaced every 6 months (check the price on them if you think it's cheaper to operate) and contain silver nitrate (caustic and poisonous) and copper sulfate (poisonous and registered by the EPA as a pesticide). By calling these chemicals 'minerals' they try to make them sound healthful and benign. My advice is stay away and go with salt. All the Nature 2 will do is act as a very expensive algaecide that will keep the water from turning green. However, clear water is not always safe water and if you follow the principles taught in this forum you will not have green water and it will be safe water also! Proper pool maintenance is easy and can be very inexpensive.
