    Wondering how high above the water users of T5's or T5 hybrids keep their fixtures mounted? Let's here where you keep yours.

    10" by default because of my canopy. I'd like to go a little higher, but it's more effort than I am willing to put in at this point.

    "6 off the surface (T5/LED); may drop it another inch.

    I've never used T5's. When I used T12 VHO I rested them on the tank trim, so maybe 1-2" from the water surface.

    I keep mine around 4”. I find that if you keep them higher than that, there is a possibility that the light will spill from the tank and turn the room blue from some of the fixtures light that bleeds from the top of the tank.
