After years of researching different types of heaters I have found a winner. I have 3 different saltwater systems and one in each system. I liked that you can use any controller with it. One connects directly to my Apex running my Frag system and the other two connect to their Finnex controller on my fish systems. Another reason I love it is that I swap out my heaters every year so I don't have overheating failures and I don't have to buy an extra controller every time. This saves money in the long term because the controllers do not have to be replaced. The heaters actually last more than a year, but I have a lot of money for fish and coral, so I only change the elements once a year.
