Cleaning a Hydro System...HOW TO???

I've searched high and low on this forum and it's really hard to find results using terms like "flush hydro system" and any variation there of...

anyways...I think i need to clean my entire system. it's an ebb and flow. what's the easiest/most thorough way to clean all the salts and crap out of a hydro system?

thanks all,

In addition, let's say hypothetically i tried to treat a Mg deficiency with Epsom Salt and now i regret doing it (the board was down for 2 days so i had to go elsewhere for my info...rollitup.org, thegrowreport.com, etc.). I put way too much in the res (i know...i know, bad move...sorry). so how do i clean the plants/medium off as well as the system?

here's what i have:

5 White Rhinos
Ebb & Flow in pH'd Hydroton
5.8 pH (consistantly)
1400ish ppm
30 Days Flowering
400w HPS
GH 3 part Nutes (following latewood's recipe)
70-80* F canopy temp
50-65% humidity
lots of air circulation

Here's a link to the discussion of my problem:

Fill up the res with just plain tap water at correct pH, and some cannazyme if you like (recommended).
Raise your lights.
Run the system for a couple flood cycles, then drain it out and do a complete res change. You can but the res back empty and use a pitcher to pour pHd tap water through the medium to wash down any remaining salts. Of course, dump this too before re-filling.
Now right away go back to a moderate level of your normal ferts.
