Take a look at Watts NO WASTE WATER RO system. I am vary happy with mine. I had to buy the DI filter separate on amazon. The same vender sells replacement filters for the Watts, and also resin for the DI. It is the no waste water design I like the most it is more expensive but saves in the long run. There are now copy cat ones out there.
Mine never gets that bad lolWhy a " silicate buster ". I have never heard of that. Also I see the pump. Is yours zero waste? Yes here is what my city water does to m

4-6 stage systems are common. Get a hold of air water and ice out of flordia for all your water needs. They'll set you up.

I have municipal water. Attached are the water test results. I'm not sure how many stages are ideal for an RODI system. I've been purchasing RODI from my LFS up until now.
What are you looking to spend, and have you asked the city if they use chloramine to treat. Most of the time it isn't listed as being used even when it is.
If chloramine is used you will want at least a 5 stage, without chloramines you can get by with a 4.
Some further reading if your interested:

There are always a lot of questions regarding which RO/DI setup do I need, how many stages, how do I know when to change filters/membranes, I’m getting a weird TDS value, etc. Hopefully this clarifies a few things and helps some of you out one day. My first recommendation would be to find the...

My incoming tds is 2-300tds your lucky with the well, are you in the city or out where it gets nice

Use a carbon block rated for chloramines if they use that to prevent bacteria in your water.
I would also like to point out additional stages are just using a 2nd of a stage you have in a 4 stage. Like 2 sediment filters, 2 carbon blocks or multiple DI stages.
Some people split the DI stage into 2 or 3 stages and use a single anion/cation type of resin bead in each and a mixed one last. This is usually done on well water.
Stages can be added easily if you start with a 4 stage and want more.
I started with a 4 stage from BRS and added a second DI cannister just so I didn't have to change it so often.

You are lucky. I had to deal with peoples wells quit a bit. They get runoff from whatever the farmers use, E.coli, and Sulphur. Even a good well can go bad literally overnight. Someone builds a home drills a well hits Sulphur. Then everyone gets it.

Does the diverted water go into some sort of reservoir before the hot water heater?
This is something I'd be interested in
No it does have to be installed " piping" a certain distance from the heater though. It uses a pressure pump to force water through and back into the water heater. Both tubes are connected to the heater. I did not read the distance from the tubing connection requirements until I was done My fault still works. Get the brass fittings work great

I like the highly inaccurate statement that other systems waste 12 gallons for 1 gallon of RO.... even the least inefficient systems produced today are around 4:1
