T5 Height Above Water

[mike31154]

My T5 fixture is just under 3 inches from the surface. The endcaps are sealed with O rings so it's safe that way. I do need to clean the salt off the bulbs periodically, depending on how much my VorTech pump is stirring up the surface. It's proven that distance is very important when it comes to light loss, more so when trying to penetrate water.
