Cloudy days

[marie]

I have the sun shine on my tank in the late afternoons sometimes and I realized that everyday is a cloudy day in my tank compared to natural sunlight...and my metal halides are pretty bright

[o.c.d.]

I looked into i light rail to simulate clouds. There is a rail the has adjustable speed, all the others are way to fast. I was focused on this for quite a while and found quite a bit of " it won't do much". I looking for less power consumption for a added frag tank, it would be long with a light rail, one light running back and forth. I tried to say "simulated clouds" but the people just weren't buying it. Anyway you could try just a light diffuser panel with some mesh and every day move it over. Just a really slow moven clowd. Some of the info on this subject was in "The Reef Aquarium"

If I do a waterchange, add new carbon, or new corals I will turn the halides off for a day or two.

May I ask why for a day or two? Do you find that your tank overall doesn't stress as much? Just wondering.

Any others do what Myka does?

I was wondering if my corals could do better with a break from sun light.
