I've finally removed all my sand. I got sick of all the dissolved organic issues with a SSB. Phos was running .02-.03 and I was still having issues with the sand. If it's siphoned regularly you should be fine, but is just as much work as siphoning a bb/starboard in my opinion, without being able to truly see what you're exporting. The benefits really come down to looks (if you're that way inclined, I prefer my starboard now - took a few years of ssb's) and keeping certain species. Zeovit suggested a SSB, so I did. Now all I did was replace my skimmer with something people would consider overkill, but I saved myself the expense of a whole lot of little blue bottles. A lot of people make them work, yet at the same time a lot have problems. It comes down to how you look after it. A SSB is definitely not a set and forget.
