I have hear more than a few people refer to the modern reef RKS system as a 6 part method not a 4 part due to the CRF/Polypop. To slings point I have not seen enough people using the system to see whether the addition of those 2 products actually makes a difference.
Another question I asked MR was in regards to water changes. They do promote water changes but not weekly. The suggestion was more like once or twice a month. I like this answer since I have never understood the logic behind zero water changes. We only test and know about a small amount of what is actually going on in the water. A great example of this is the yellowing of our water. Changing out old water with new is in my mind the easiest and most reliable solution to get some of these things out of the tank.

. Good luck getting your MR system up and running soon.
