150w HQI bulbs

[VFX]

Thanks for the update Doug. I appreciate it.

How deep is your cube? How high up is your light?

My cube is 20"x20"x20" and my light hangs 6 inches from the water's surface.

Your corals seem very happy under the Phoenix. if you're getting good grown despite the reduced par I think I'll give them a try.

Same for me. My fixture is 6in. above. Tanks only 16in. though. I have acro,s a good 17in. under the bulb however. A colony of green, brown and orange digita frags in the bottom corner, is about 24in. from the bulb and show good growth. Or at least good enough for me.

Derasa, hydro and milli,s on the bottom also look fine.

My fixture only has a couple of 18w actinic supplemental bulbs so while they give a nice evening look, dont add much to the par, so whatever light, is mostly from the Phoenix.

Good to know.

All of my SPS are within 22" or so from the bulb. The only things that has shown good growth had been hystrix & monti caps.

Anyways, I just picked one up so it'll be good to see how it compares to my Current-USA-comes-with-the-fixture cheapo bulb.

Thanks again Doug.
