Was the glass hard to put into the fixture? Getting it under the grill might be a challenge? Anyways, I'll keep this in mind, not too worried about it.

Aha, you have asked the right guy! As you know, the grill is actually removable. Both ends of the fixture you can pop out the plastic end cap, and slide the grill out. Now, the other nice thing coralife was so nice to do, was have mounting pegs at either end of the fixture, so you can install a second fan.

I ended up buying two sunon maglev 3000rpm fans that run @ 6v, 40mm. I can get the part number when I get home. Incoming voltage is 12v, so it works nicely have 2x6v fans = 12v, no extra wiring, wall warts, or under powered fans.

I never actually finished the mod though, it was tough to get a glass shop to order me such a small piece of tempered glass. (Maybe I will check a few places today .. hmm hmm!) I just kept running the glass top on my nanocube, and it really helped with evaporation.

The only reason I wanted to use tempered glass is for the sake of higher heat rating. Glass shop guy said 3mm glass should be good to 165C...

My bulb is about due to be replaced ... My thoughts were....

I'm either going to buy a corallife 20k bulb

OR

Find an old broken 24" fixture, cut it down to fit my tank, retrofit the 150metal halide into it, run a 10k bulb, and retrofit 2x8w actinics into it... I have a feeling it will end up going the DIY route

my fixture was is a coralife aqualight advanced and the bulbs were 20k coralifes and making the switch to the geissmans about 2 months ago has only given me better color and growth....

i just upgraded to phoenix 14k 150w bulbs yesterday. I had coralife 20k bulbs for the longest time and got nearly 0 coral growth. Colours were good but no growth. I'm liking the phoenix bulbs better already - a good mix of blue.

I have had the 14k 150w Phoenix on a 30 gal for about a year. Really intense blue. I put a Digita and a Monti Cap in about 1 week ago and have already seen about 5mm growth on both...

You can get it on marinedepot.com

Here is a picture of the Phoenix 150w 14k in the early days of the tank.

Nazerine, funny that they made their fixture different between the advanced and the Aqualight pro...I have used many bulbs in my pro...never had a UV problem and I have the light down to within a few inches of the water...I e-mailed Coralife when I saw your original post and eventually they e-mailed me back that it was in fact a UV glass shield on the Pro but that's all they said.

Hmm, that might explain a few things if there's two different versions!

Does your have a glass plate in it, or a finned aluminum diffuser??

My has a half c-shaped 'splash guard' for the bulb, but it covers like 2/3rds of the bulbs and thats it.

The Aqualight pro has a full glass plate in it and no guard around the bulb. The plate is 1/4" glass.
