Texas is a state where problems with salt water chlorinators seem to occur, and thus there's more controversy. The issues in Texas seem to involve dry areas (where salt water splashout dries, but is not periodically washed off by rain) *plus* locally available stone that does not tolerate salt buildup well. Your registration included your address, so I checked: given the trees shown in the Google map of your area, you are probably NOT in one of the trouble areas.

Still, salt does increase corrosion, so:

1. Use brass, not aluminum, ladder and rail anchors. (Should do so, anyhow!)
2. Make sure any light installed is fitted listed as salt resistant -- or use a stainless steel fitted lamp.
3. Make sure any heater installed is listed for salt -- this is critical; check it for yourself and do NOT take your builder's word that it 'will be OK'.
4. Make sure all valves installed are PVC, not brass or bronze.

Other than that, you should be fine.

Carl's right about Nature2 -- it's a waste of your money.
