Uh oh, did I miscalculate?

Peter,
What about a lower flowing pump and installing eductors on the returns in the tank to increase the flow. I just did that on a 72 G bowfront I picked up this weekend. Got a Rio 32 for a return pump, 1500 GPH and ran 2 eductors on the output in the tank. Adds some serious flow without the extra heat. Just an Idea.

Yes, that's an idea. I'm going to make the final decision once all lights, canopy, fans etc are in play...we'll see what the temp ends up being. Thanks for the ideas.

Just to finish off this thread in case anyone uses it...

So this is what I ended up with:

Two 4" fans blowing into the canopy. The entire back of the canopy is open. Three 4" fans blowing into the stand (one directly onto the back fan of the hammerhead). Multiple holes in the other side of the back of the stand for the hot air to escape. On the hottest day of the summer (well over 90F), with all equipment running, and all the fans on, the tank hit around 89F. So then I knew I needed a chiller that only had to pull down about 7-8 degrees F on the hottest of days.

Even if the chiller fails, my tank will never hit a deadly temp. Also, the Neptune Jr. is set to turn off MH lights at a certain point, and alarm at another.

Glad you got it squared away.

Do you have a link to pictures, etc?

I just continued this thread with the new tank. Not sure I have pics of the fans per se, but most of it at least:
