Name that one thing to get a stunning SPS tank

[Dez]

I agree with water changes. I've been doing weekly minimum 40-45 gallon water changes since I started my SPS tank in August 09. The only time I've missed is when I've gone on 12 day vacations. I would say that my aquarium is pretty successful - good colours, good growth and hasn't crashed yet (knock on wood).

H2O+NaCl is at the top of my list

In my case O.C.D has been my biggest helper. That's ocd. Cash & diligence.
