How high should my leds be mounted ?

[jorge0912]

I have two hydras 26hd on top of my 75 gallon reef tank ?
One anemone bta
I have some sps
Digitadas and montis besides that
Pretty low par coral like. Leathers
And hammers zoas
I have the lights mounted around 12 inches above the water with the brackets I got with them. Running the David Saxby program with them ...
I was wondering if they should be a bit more gift her or are they fine the way they are

How deep is the tank?

Zoas and leathers are not low par corals really. They can tolerate low par but most do best under very good light. The best led tanks I have seen all have them hung high up and ran at 100%. So I would start high, with the lights up as high as you can get to achieve the color you like then move them down if you need more light. This will keep you from tinkering and causing corals acclimation stress.

Whoa...dont go running those hydras at 100% youll toast everything...
They penetrate 24" deep which is why id like to know how deeps the tank and the saxby is a good program.
