Lighting Schedule & Chillers

[kevintang]

I am sure this has been asked 1,000 timest but I was curoius to what others are using for a lighting schedule. I have:
2 MH 400W
2 VHO Atintic
2 Moon lights.
I have heard corals need 6 hrs of MH light. Also, I need to get a chiller to bring my tank down 4 degrees, in March. It could be more by mid summer. What size should I get for my 125, 1/4 hp?

To answer the light question I would probably give it somewhere between 6-8 hours a day. From experience it seems to me that you can just turn them on(or have them turn on) about the same time you would wake up and have them turn off about the same time you go to sleep.
As for the Chiller question I havent had much experience with a chiller so I honesly couldnt tell you a specific size.

I live in SW Florida and my 1/4HP works great on my 90. You shouldn't have any problems.

6 - 8 hours a day of total light or MH light? Also, any input on running other than 2 atintic VHO's like one white or PC?

6-8 hours total light will be fine. Personally I would have the lights come on something like this:
Actinic blues first, about 30 min to an hour later have the Whites and MH come on and just let them all go for about 8 hours then have the Whites and MH turn off and again 30 min to an hour later have the blues go off.
I havent had alot of experience personally with MH but have worked with tanks with them before and that seems like the way they work.
