I have been using the BRS pellet GFO. I have been happy with it so far. The reactor is easy to use too. I am sure that any of them will work fine though.

thanks for the comments Jmatt567. I always use 0 tds water I get from my lfs. They have reputable water and it gives me a reason to see what they have in stock. I've also tried the blackout method and didn't see any benefits. Thinking about it more, I'm not going to remove that much of my sandbed, just the parts with the cyano growing on it. I think I'm going to try a weekly 20% water change and a phosban reactor with GFO.

I'd research sandbeds some more.
A (denitrifying) deep sand bed requires sugar size sand of 4" or greater in depth. At 3" a sandbed is still considered a shallow sandbed and it might possibly be the most challenging type of sandbed to maintain as organics hidden in it can continue to be a source of fuel for cyano. Even worse, the presence of high levels of phosphates can inhibit calcification in scleractinian (stony reef building) corals.
