I always see these huge tanks with nothing but Sps. Just makes wonder how its all done. I know high calcium is needed, so is a reactor a must, a refugium??? Sps only?? My LFS has a 180 with SPS, LPS, Zoas, and softies and it has been thriving for years. On the other hand the most respected LFS guy says do not mix Lps, Sps, and softies.. So... I dunno, I see sweet tanks and I would like to someday have one myself.
