How long to you run your metal halides
I'm curious as to how long people run their metal halides per day. As a follow up question do you try to simulate cloudy days, or darker days but not running your halides at all?

Michika,
I may turn on the PC actinics before & after (for an hour or two), but otherwise only use MH. Have 3x 250w DE 14,000k Aquaconnects over the big tank & 175w SE 10,000k Reeflux over the "cube" frag tank. Also have moonlights over both tanks. Anthony

Two 48" actinics on from 6:00am until 10:00pm
Two 250W MH 20,000K geissman (sp?) from 8-8 well, to be totally geeky, the east light turns on at 8:00 am and turns off at 6:00 and the west light turns on at 10:00 am and turns off at 8:00 pm. I have a large anemone that I need to keep on it's cliff and by allowing it the last two hours of light, it stays there all night. I use three outdoor timers that are specifically designed for block heaters. I got them at home depot. They are waterproof, have ground fault built in although I use ground fault receptacles as well, also they are made for the full 15amp load. I've been using them for two years without issue. Although when the power goes out for any length of time my corals move time zones.  my two bits.
