Temperature Control....gotta loose some heat

[jgoldsney]

Well, the new tank is up and running and the 400W hallides look awesome...the only down side as I expected is the heat.

I will be adding a couple of 12V fans blowing directly down on to the water but I am looking for any other ideas to keep the temp down.

1. Could raise the lights a bit higher.
2. A couple fans blowing across the top of the tank instead of straight down.
3. Air conditioner for the room.
4. Chiller.

I installed a couple of radioshack fans in my light hood and they work like a charm. During the summer months when it gets really hot I also have a 1/4hp chiller that gets the job done.

Well it looks like Fans are a viable solution.

I put a 120v small house fan blowing in from the back corner (it is a corner tank) and I lifted the lid with some blocks 1/2" to allow the hot air to be forced out. I ran my hallides for about 5 hrs last night and the temp only went up 1 deg.....now only if this will hold true over the summer.

do u have a lid on your tank?
If so, I would think that is the major cause of your heating problem. I think that the lid would act like a magnifying glass under the MHs...
I dunno..but just my opinion.

with 400 watt lights you are probably going to have to invest in a chiller.
