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.

Yeah, the Aqualight Pro's have a plate of glass covering the bulbs, while the Coralife Clamp-on does not.. so silly to me.

Either way, I am fairly impressed with the unit, it's a hell of a lot nicer than the old Coralife PC unit I had on the tank. Nice "open top" (still eggcrate covered) but nothing sitting on the eggcrate. The unit is sleek, small and nice on the eyes, no complaints.

Nazerine, do you find that your unit makes "rattling" noises? Mine keeps rattling , and it gets fairly loud. I thought it was the metal grates loose and rattling, so I took it off but that wasn't what's causing noise... I may take it apart tonight and check things out.

Sounds like when I do change bulbs, I'll try out this Phoenix 14k. I've heard nothing but good things about it. Thanks a lot for all the input.
