I'm so guilty of this. In the spirit of trying a lot of stuff so I can help out around here I have completely over-engineered my setup... I've got a calcium reactor, tunze controllers for pumps and top-offs, halides with moon lights, I.V.'s, pH controller, hang on the back skimmer, timers galore ... all on a 20 long! I had bigger tanks with so much less that did better too. Go figure! : Has your reef setup become too complicated?
