    Long story short:

    1) My LEDs hand 8" above the water.

    2) I have mostly SPS coral.

    3) Corals are approximately 10-12" below water line.

    4) They are dimmable LEDs.

    5) There are 2 T5 bulbs (ATI Blue Plus, ATI Cora Plus) for supplementation

    6) There are 24 diodes over a 2 square foot surface, so narrowing the focus ( plus T5s) isn't a huge concern. I just want to insure SPS are receiving adequate PAR (which I plan to measure this weekend).

    Bought 80s today. I was told not to use super glue. What should I use?
