Tbittner hit the nail right on the head.
If your filtration, skimming, circulation, and lighting is not up to par (no pun intended) spending money on an expensive controller will not give you a lot of return on your investment. Your system will still be limited by the other factors.
To give an extreme example, if you want to keep clams and your lighting is a single NO fluorescent bulb, no matter how fancy a controller you use, you still will not be able to keep clams alive for any length of time.
