Has anyone had the tap water in Gainesville tested? I run a three stage ro/di. But wondering if I need to add a 4th. for scilic

Below is the Gainesville test report for 2018, which does not list silica. Here-

I found a reference showing about 35ppm present in south metro Atlanta. That should provide some idea of what to expect in N Georgia.. Here (pg 22)-

Your pH in Gainesville is about 7.87 and alkalinity at 16 ppm (16mg/L).
Soluble silicon usually exists at silicic acid and that requires a low pH. Otherwise is reacts with a base and precipitates out of solution.
Here's a reference stating that RO removes 85-90% of silica, which means along with your DI stage(s) the anionic resin should get most of it. Here-

So, I think you should be good.
