P.S. Did you purchase your Lumenarcs already set up to house 2 moguls or did you have to cut a regular one? If you bought it like that already, where did you buy them?
Also, what kind of fan action do you have going on to keep those things cool?
Thankyou
Matt
Are you thinking the hydroids are the white ones at the top of your photo (not the other stuff in the middle of the frame)?
I ask because I think I have some of these white ones too.
why are red LED's the preferred spectrum for night scoping? As compared to blue LED's? I have been using a flashlight but it disturbs the crabs and fish when it points in their direction.
