The media guard is one of the best, and worst items in this industry. It works very well if it is installed correctly and maintained properly. Unfortunately, I have been to way to many places that had them installed improperly and they caused a lot of problems.
The most important part of the media guard is that it must have the DLFC adjusted correctly. And they will flow much past 10 GPM. Assuming a water temperature of 65 degrees, the DLFC should be adjusted to 4.0-4.5 GPM. A standard 10" tank will be set at 2.4 GPM, this is too low for the media guard to self clean, and it will fail in a short amount of time. They should be changed out every 3-5 years maximum. Remember, these only 3-4 pounds of media inside of them, that is a tiny amount of media for a POE residential application. Even at that small amount,they are surprisingly effective. I can understand Garys and many peoples reluctance to selling the Media guard. Too many people did not know how to use them properly or misapplied them and they will restrict flow rates etc. Many people see that they reduce chlorine, and then expect the media guard to work after chlorine injection...
I recommend it on smaller houses only, up to 2 bathrooms max. Change it every 3 years max, use the proper DLFC, and they are actually quite good. But if someone says not to use it, I would not argue with them either.
I doubt the media guard could be added to your existing system. We sell a huge number of media guards and have had nearly zero problems in the past 5 years with them,
