IMHO
Water changes, LR in the display, quality skimmer in sump, media reactors for carbon/gfo, and filter socks but only if you can change them out every day/every other day. Nothing else in the sump. Just keep the system clean and your SPS will thrive.
i want to stay on topic but please share the problem you had with rox i suspect i have a problem using way to much of it.I have the Bulk Reef Supply dual reactor which holds both gfo and carbon. Personally, I feel that carbon in a reactor is much more efficient than a filter bag in the sump that passively polishes the water. I had a bad experience running ROX carbon, and personally feel it's much too aggressive, so I just run the normal stuff from BRS.
In addition to what others have said, I've found that a clean sump helps tremendously with an SPS tank. I use a filter sock that is changed 3 times per week, and also have a large sponge wedged tightly between two baffles. Every other week or so I use a turkey baster to draw any detritus out of the sump and release it into the filter sock before changing it. Every 3 months I'll shop vac the sump dry, clean the slimmer body and pump in RODI and vinegar and wipe the sump clean with a dedicated aquarium sponge before refilling the sump with fresh saltwater. I also squeeze out the sponge in the baffle with water drawn from the tank during a water change weekly. Like many have said, detritus is your enemy in an SPS tank. I'd rather remove it a little at a time rather than wait until the tank looks dirty. I also take the butt end of my Kent scraper and vigorously stir my shallow sand bed to get any gunk into the water column so that it can make its' way to the filter. Before doing this, I clean the glass and turkey baste the rocks clean. After seeing Vivid Aquariums' instructional video on performing these tasks, I've been doing it ever since. Getting the water column as filthy as possible for an hour or so every week has progressively made my tank more clean every week, and my SPS have responded very well with good colors and polyp extension.

I am having similar issues colors fading and browning out. My system calls for 2 cups and I ran 6 cups to get rid of a cycling odor (I added a tank to my system). So I stopped it and seems things are getting better after a day or two.Where do I start?
Switching to ROX was the only thing I changed in the system at the time, and I noticed a reduction/death in coralline algae growth, recession of SPS corals at the base, pale colors and decreased polyp extension. I lost many LPS at that time as well.
Some will point to things like increased water clarity from ROX, but many of us (especially in this forum) know our tanks pretty well. My water was very clear when I made the switch, and I never noticed an increase in water clarity above what I already had. It just seemed cheaper at the time to run ROX at a reduced amount than the bulk stuff. I even ran half of the recommended amount and it still happened. I took my carbon and GFO offline and added an extra feeding, since I believed a large water change would compound the problem.
Slowly, things returned, but some SPS and all my LPS were lost during that time. I didn't change my photoperiod, add a new coral, change bulbs, add a new fish or change my salt brand. ROX for me was a really bad idea. While I ran it, my skimmer actually pulled a lot less foam as well, so I knew it was stripping nutrients (and who knows what else) much too quickly. I personally feel it's just too good at stripping available nutrients in a tank and leaving next to nothing for other organisms to feed on. I'm sure there are many that use it successfully with no issues, but there are many others that have experienced the same thing as me.
rox is grate but you dont want to run it for a long time...rly i would save your money and buy the cheaper carbon
Totally agree. I'd rather change it more often than use ROX again.
I use lots of live rock and denitrate man that stuff works
