Wiring a fan

Laura and Jim will be hosting the May meeting this Saturday the 12th and it will be the usual of food, drinks, raffle and fun.
 
Doors will be open at 6:00 pm for social talk and the meeting will start at 7:00.  Parking gets a little tight and the city says you can't park on 4th but there is a parking lot a block away.   Meeting is usually held in the backyard so feel free to bring your favorite lawn chair, weather permitting of course.

If you need address/directions, contact a club member.

Best if you park at Mini Mall (where the spaghetti establishment use to be)
 
You will get to see his new frag tank set up in the making.
 
Hope to see you there!

Ok I have three MHs and I want them to all come on and off one at a time simulating sunrise and sunset.  I would like to know if I can wire a fan to the last light so when it comes on so does the fan?  or should I wire it in on it's own?  I eventually want to set it up on a temp sensor but don't have the money for fancy stuff right now just the necessary stuff.  Any ideas? Thanks

Sure,

Just plug the fan into the same outlet the last MH ballast is plugged into.  It will come on and go off with that fan.

BTW, your tank brace is drilled and on the front porch waiting for you

Thanks for drilling the brace but I am confused on the fan?  I guess I didn't mention the fan is PC fan and I am thinking of hard wiring it in.  Sorry for not making that clear.

If it is a PC fan, you will need to get a power supply for it.  You could pull one from an old junk pc and that would work.  Then you would plug the power supply into the same power source as the lights.  

Since PC fans run at +5 vdc or +12vdc you will need some type of power supply for it.  Another option is to get a small power transformer that has the correct output for the fan.  Radio Shack can set you up with what you would need, just take the fan with you.

No chiller yet.  Want to see If I need one before I buy one.  My house is always pretty cool inside and I didn't have an environmental temp issue with the 55g (one time the heater went on the fritz though).  Thanks for the input.

You will Angel Unless you go with Fans & evaporation = This is ok and how i did it last summer. I was even down to running the Halides for only 8 hours to keep the heat down but with fans you will evap out about 3 gallons a day Good luck Angel I hope it works for you    You may have a little edge with Your home being cooler Another thing is you can shift your tank Contants to one side use the halides on one end and the center and on other end you can shut down one light during the hotter months ...

It is one thing to have something and not need it than to need it and not have it, but that is one expensive thing to have just laying around.  I still have the holding tank set up and hopefully I can make that determination before all the corals go in?
