View Full Version : MH DE Bulbs orientation, actinic T5 or VHO?

I'm setting up 3 x 250w ReefOptix III penadants with DE Bulbs.

I'm thinking hoirizontal to allow space to add a T5 Actinic fixture in the back.

The tank is 172g bowfront 72 x 18 x 24. Should I run the 3 ROIII pendants perpendicular or horizontal?

Also for true actinic 03 supplementation, would T5 be a better choice than VHO?

The MH bulbs are XM 10K DE.
