I am going to upgrade my antique Pool Equipment, Heater, Pump, Filter & Diverter.
22,000 Gallons, 10' diving Pool with Hot Tub.

Goals:
1. Quiet Pump: Opinions & or recommendations?
2. DE Filter: Pro's Con's Hayward Composite with Diverter? Alternatives?
3. Gas Heater: Not Cheap - Not $7K
4. Pool Lights: LED Bulbs Conversion or All New LED Specific Housing?

I Know from experience that every Pool Owner has had these issues & I welcome advice and Opinions.
Thanks Ron D.
