Mh


Recommended Posts

For the casing and ballasts you can use the commercial type. As for the bulbs..you might have to buy specific ones with suitable kelvins. Try to go for 6500K-20,000K..depending on the coral you are intending to keep and the color of the tank you are hoping to achieve. :rolleyes:

Always something more important than fish.

Not sure about that.

Have used non marine 150W MH for many years in past without problem. Should be ok as long as double ended has a cover glass. The units in question are proberbly used in shop displays(repaced bulb with 10,000k of course)

I thought UV rays do not pass through glass only IR (check out greenhouses)

Please correct me if i am wrong

Glass is not totally opaque to UV. Some amount will get absorbed or reflected but surprisingly large percentage gets through.
