	Manhattan Reefs Manhattan Reefs, the best aquarium community on Planet Earth!

	MH Metal Halide Lighting, typically used for high intensity light demanding corals such as SPS. Bulbs come in varieties of spectrums (7k, 10k,20k), and intensity (175W, 250W, 400W).

	VHO Very High Output Fluorescent Lighting - Fluorescent bulbs that run on special ballasts and have an output that is significantly higher than normal tubes. It is very possible to run an entire reef system on VHO lighting providing the proper number of bulbs and mixture of spectrums are chosen. For most hobbyists, these tubes are used in conjunction with Metal Halide lighting for simulating dawn and dusk. They often provide the "bluer" end of the light spectrum and thus a more aesthetically appealing display.

Paul.

i would like to get 2 new ones if i can ,,or 2 of the same usage.....how many watts?

have you seen 20K's ? they are really blue.and 20k 175's would be pretty dim looking.

I'm using URI actinics, they are about as blue as it gets.

[nanoreefer22]

Yea the 20k's in the 175watters would be really dim looking. The URI actinics are really really blue. I love those things.

contact Tony at http://www.reefexotics.com he is in Long Island.

not so good, unless you have a tank with coral that like low light.
this would be good for a deep-water biotope

should i stay on the 10 k ,,,i see in that site reeflux MH 10k bulbs are they good ?

I do have 2 of each. 175W.

Hamilton 14K one month old $40 each, and Aquaconnect 14K one month old $80 and another six months old $40.

You are probably wondering why the difference in age, as you can see from the link below, I was experimenting with different bulbs on my old 65 gal. So, one side was lit by 14K and the other by 10K no acctinics. Since I have upgraded to a 210 reef, I am no longer in need of 175W bulbs.

IMO, the AC 14K are by far the best looking bulbs for a reef tank, in the six months I have not noticed any deminished growth of SPS compared to the 10K XM.

The Hamiltons, I did not like. Color was nice but not as intense as the AC. If I remember correctly, the AC has almost double the par of the Hamiltons.

If you`d like, you can keep the bulbs for a week, and if you`re not happy I`ll take them back no problem with that.

	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.
