Being we are buying reactors and running the stuff active, do we rinse and spit or not rinse and spit?

I think everyone recommends rinsing new media to a degree. Here is what I do. I change my media in the kitchen sink, With hoses attached to the reactor. I have an RO water dispenser at my sink, the 1/2" hose fits snug around the RO faucet. I slowly run the RO water through the reactor. You watch the fine sediment slowly rise in the reactor, dont do this too fast, all of the media will rise in the reactor also, you dont want this. You just want the fines to rise and exit the reactor. This takes me a few minutes.
There are a couple of Sponge Filters that come with the reactor. These filters will guarantee that you dont get media in the tank, but they will also get clogged up over time forcing you to change the flow on your pump. They get clogged with all the normal sediments from your tank getting into the pump and into the reactor. I've learned to not use the Sponge Filter on top. To do this you need to know your reactor and how not to let media rise too high in the reactor. You do this by using the right pump and/or adjusting the valve into the reactor.
One Important Note - Restrict the Flow Entering the Reactor not Exiting. If you restrict the flow on the Exit side you will be building pressure inside the reactor, and the Reactors are not built to withstand pressure.
Back to Rinsing Media. This is something you will see wide variations of opinions on. There are people that change there media at the time they do a water change. When they drain the water out of their tank, they run it through the new media in the reactor. If I did that it would be approx 30 gallons of water. The theory behind that is, the water in your tank is already Phosphate Free. So rinsing the media with Phosphate Free water is not taking any of the value away from the new media. People feel that a lot of the bad reactions that the media causes is caused by new media and what it adds to your tank.
You will read that Rowaphos does not really recommend rinsing your media in this way. In my opinion, over rinsing in this way is not needed, but I do insure that all the fines are removed before I add it to my tank.
It's also not a bad idea to let the water exit the reactor into a filter sock in your sump or wherever. I do this in the beginning with new media just to be sure.
I dont want a PO4 Test Kit. I'm going with the theory that if I run this media, I will have very low PO4. I do have a Salifert kit that measures higher po4 levels.
