    Hi All

    I am running a 1.2m tank, 250L (I think). Somebody recommended that I get a Submerged 36inch LED unit, which I could put into my canopy and would be sufficient lighting for my tank, to grow corals etc. It has a 50/50 split of coral blue and white LEDs.

    What do you guys think?

    will it be submerged? Or above the water?

    If submerged, you will need to clean the lens a lot. If mounted just above, and within canopy. And it is waterproof, then it would prevent water damage. But must look at heat, if in an enclosed canopy, they LED unit will run hot, reducing its lifespan and heating your tank.

    Almost always, LED units get mounted 25cm or more above the water. Not like the old T5 that was 5cm from the water.

    Thanks @RiaanP

    It will be mounted in the canopy.

    I am seeing the guy today. He seems to think it wont overheat and has told me that if I am not happy, he will not charge me...

    how high is the canopy?
    What will you do for extra airflow? Add a fan or two?

    If its one of those lights that are made to be placed under the water, then dont take it. They designed to add colour to freshwater aquaria and will not be nearly sufficient for any coral.

    Thanks for all the help guys.

    After much consideration,I have decided to go with a quad T5 unit for now.

    Will save up and eventually get a worthwhile LED unit.
