Clear O3 ozone with fusion inground

[rachel9497]

This is our first pool and we arr close to hiring a PB that we like who is recommending the Clear O3 ozone with fusion inground chlorine and mineral system. The other PB's as well as neighbors all recommend salt systems. I would like your thought on the way to go. We live in Atlanta,ga so its hot and humid.
Thanks

We don't think too highly of the ozone or mineral systems. Just stick with chlorine -- which is what a salt system pool is --- a chlorine pool.

Watermom is nicer than I am.

I'll put it another way: almost without exception, the ozone systems installed on residential pools in the US come in two flavors:

• those that are useless; and
• those that are harmful.

What none of the ozone companies tell you -- and what many PBs do not know -- is that ozone and chlorine destroy each other!

I got my first nasty-gram of the season from someone in the pool business a few days ago, from the head of some sort of pool builder's association in New Zealand. He'd find my ozone tips page on PoolSolutions and unhappy. His level of knowledge about ozone chemistry was poor, to say the least.

BUT . . . keep in mind, that many good pool BUILDERS are really terrible at pool CHEMISTRY. If you're builder is good at BUILDING pools, just say no on the goop he's trying to sell, let him build your pool, and then ignore his pool chemistry advice.

Regarding "mineral" systems -- they are excellent at green hair and pool stains, because they add copper to the water. They would be OK for fountains no one was swimming in, so long as the fountain basis was dark enough so that copper stains wouldn't be a problem. But, they don't belong in pools.
