I love this unit and has served me very very well! It did start to leak into the light sleeve but after 6 years it could use some maintenance and new internals. A replacement light sleve is $30.The leak did cause 1 red led to burn out but light still functioning as should. It is the c30 model and sells for 1650 new asking $700. Its a beast and really works. Sadly it's just to small for my large system. I am replacing this unit with a 90gallon refugium. Located in bellingham
