Will do. Everythings looks great today - water is very clear, and the temp is under control with the cooling fans.

I went with 2 PC type cooling fans that have 3 speed levels - and some pretty lighting effects. Hooked them up in parallel to a 1000 milliwatt 12V DC transformer.

They only come on when the MH's come on, so the lighting is not noticable at all. I wish I had some sort of temperature/thermostat to run the fans.

You can buy fans of this sort

BTW, the finished pics were very nice.

They were cheap ($10 ea.), locally available, and I needed them quickly.

With all the people going through the house, the ambient temp was going from 69 in the morning from the doors being open most of the time with people coming and going (where they have it set to supercool the house), to 84 in the afternoon. I didn't expect the house to heat up that much, but I also didn't expect it to be near 100F this week

I have my dual 250W MH setup and reflectors. The PFO 15" reflectors are nice - very mirror like.

Ellisz, did you mount yours directly to your canopy, or hang them in some way? I'm looking at options, like building a hanging bracket to keep them away from the top of the canopy and heating up the wood (melanine actually) in there.

I run my fans 24/7. I use PC fans so I can control the speed with a variable AC/DC power supply. You cant here them. I use Panaflow L1's.

I left a air gap between the top of the canopy and where the reflector was mounted. Mainly for air flow but I wanted to lower the lights a bit too. My last tank, I mounted to the top of the canopy. When I tore it down after 3 years, the canopy looked fine. I don't think it gets that hot ...

Long night.

I tried mounting 250W's in my home-made reflectors tonight, which are currently mounted directly onto the bottom of the canopy, which are covered in melanine - standard cabinet interior stuff.

The wood got pretty hot - hot enough I'm not comfortable leaving it that way. I could touch the wood under the reflector (by reaching in), but it was hot to the touch. Not too hot to hold my hand there though.

So I proceeded with the long - term plan - I have four PFO 15" reflectors mounted to a 2x4 (2 for 250's, 2 for 175's) - and am planning on hanging that for easy maintenance (as opposed to mounting directly to the canopy interior, which is real hard to drill through and tends to chip.

Anyway, going to hang that, with a couple small chains and 4 hooks, down maybe an inch or two from the top of the canopy (it's 18" tall inside).

The canopy has two compartments. One open one over the tank, then a shelf above. Right now, I have a fan blowing into the top shelf, then a 2nd blowing into the tank space.

I'm going to add two more fans - blowing out of the tank space, and out of the top shelf, but I'm still worried about the bulbs heating up the 2x4 to the point of combustion...

Anyone ever had any problems with 250W MH reflectors mounted to a 2x4? These are the 15" batwing PFO reflectors...

Scoot, amazing pictures!

Your tank is lovely and blends perfectly with the house and decor.

After doing some reading, I'm going to go to Lowe's and find a metal bracket to mount the reflectors and sockets too, then hang that with at least an inch of space between the top of the canopy and the reflectors. I don't want to rely on cooling fans to keep the wood cool enough to not catch fire

I've got some aluminum (L-shaped stuff, not sure what to call it), and hanging hardware. Haven't had a chance to do anything with it. My condy has climbed up the back of the tank to the top of the waterline. I'm guessing to get more light, so I need to move on this tonight. The bubbletip has found a home on a rock towards the top, and hasn't moved in a week.

Water looks good - really clear. Fish all look good. Xenia's are coming around.

But none of my 2 varieties of GSP's are coming out much, just enough to see the 5-points. The Galaxia looks the same as always, but the GSP's are concerning me. Any suggestions on that?

The mushrooms look great - better than ever before. I think they like their new home.

My GSP's always took a long time to come around after a traumatic event (moving, taking out of water, etc). I just took mine out of the water for a bit a few days ago to pick out some algae that was growing on it and I probably harassed them quite a bit. It's been a few days and they still are only poking out the tips, so maybe it's normal? How long has it been?

It's been a couple weeks now. They're not dead - but they're barely coming out, for just a few hours a day.
