The joys of reefing

i read that when using RBS you only do 5% weekly water change for best results.
what are you(s) doing for water changes--amounts etc?
(i ask because i am thinking of going Zeovit route)

I change 10% every other week with RBS. I've never had a problem with it, the corals are all fine. I suppose if the environment was way off using some other salt, that switching could be a problem, but I changed out 25g my first switch to this salt and had no issues.
