AquaControllers have their quarks, but it is still well worth the expense and occasional frustration. Three times I would have lost my entire tank if I hadnââ"šÂ¬Ã¢"žÂ¢t had the controller set up with safety codes and alarms in place.
Once I forgot to turn off the calk pump, once I left the state for the weekend; the weather was cool when I left, so the house air conditioner was off. When I got home, the temp was in the 90ââ"šÂ¬Ã¢"žÂ¢s. The AquaController had shut down all the MH lights and turned on all the fans and the chiller. At that temp, the chiller would not have been able to keep up if the lights had stayed on. One time I was in Hawaii and at home there was a bad ice storm. The power was on an off may times and caused problems with the AC. My husband was home and is not a reefer. He is also computer illiterate and hates computers. I was able to reprogram the AC from Hawaii. The AC also sends an alarm if the power goes out.
Personally I consider it a necessity for a healthy stable reef, not necessarily a luxury.
You will also be able to maintain you tank with more constant settings, creating a much more stable environment for your marine life.
