I'm still debating whether or not to use the worm drive and move the lights very slowly.

I can add that function later.
I really have less need if I use the T5+ HQI, the spread is already there.
Moving it say 4" back and forth would help I'd think, but with the Sexy series AM lights, the travel would be about 12".
More critical there(movement) with the Sexy series to get even lighting.

I also have a Eco Tech Vortex powerhead wave maker for the 60 Cold water marine and the chiller.

They ain't cheap, but they are cool.

Regards,
