Need pool renovation advice for a 1950's pool

We have wells in both limestone and in shale, in this region. Limestone well water is GREAT, but water from shale is AWFUL.

I don't think we hear so much from the folk who have limestone wells.

We're in South Florida so I'm pretty sure we're over limestone.

As far as the main drain goes, most companies suggested eliminating the main drain but I'm thinking it's not a bad idea to at least keep the existing main drain. Would eliminating the main drain and adding two deep water outlets be a good idea? What would be the best solution when the time comes?

S. Florida has some karst areas, but it has some weird brackish intrusions: test that water before you use it!

Deep pools are messier with no main drain. But if you have a drain, having deep water inlets wouldn't add that much value.
