Looking to remodel my pool plaster with Quartz. Its a big decision for our family and would love to get your expert opinion. My pool size is about 20,000 gallons.

Can we get an idea on SGM Diamond Brite Quartz vs ColorScapes Quartz?

Which one is better with respect to Quality, longevity and price?
Also is it better to do 50% Quartz or 75% Quartz? not sure which is the best ratio for strength.

Appreciate your help.
