I'm becoming increasingly frustrated with my reef systems. Back in the day, I could not for the life of me get SPS to grow very well. I did seem to have reasonable luck with zoas/palys, so I switched and things started out well. Lately though, I have simply have more algae growth then zoa/paly growth, and this was after they grew well in basically the same system! Anyways, enough whining from me...the point of this is to discuss what you feel is the secret to your success. It could be a combination of things, but you guys know your systems better then anyone, so I am curious what you feel is vital to keeping the beauty and growth of your system going.
