Lifegard AquaticsIndividual Heater Module - AF-92

At about the same cost of a decent inline heater (which are known to fail over time) this heater module is an excellent addition to my system. I already had a heater in my tank, so I didn't need to purchase another one - I just slipped my current heater right into the module. If that heater should one day need to be replaced, it can be easily done without taking anything offline. It will require some plumbing initially, but once it's properly setup, you'll never need to mess with again. Highly recommend!
