How high off the water do you recommend the light be mounted?Our testing has all been done with the light 8″ off the water surface. You can raise the light higher to fit your needs. Our new hanging kits extend to 39″ to reach the ceilings in most homes though hanging your light more than 14″ is not recommended
How did you attach the angle to the fixture?
Honestly you really shouldnt have to start from that far up at all. Unless everything in the tank is low light and you are seeing immediate bleaching and ill effects, something like 20" and eventually down to like 12 would be fine
Do you have something to cover the tank while the canopy is off?
That's not good. Did you buy it as "used" or did they say it was new? Where did you find it, on RC?
... I’m about ready to pull this thing out and toss it.
But think of all the energy you're saving! LOL
What did the seller say when you told him about the broken pumps?
