    mh distance

    merry christmas to all...just want to known at what height do most reefers keep there MH lamps from the water level I keep mine at around 8 inches from water level.... but when they are new keep them at 12 inches and go down as the bulb gets older ... also is there such a thing as a break in period for a new bulb...and a happy new year

    I don't believe there is really a break in period for bulbs- many people believe otherwise- I think that any real colour shift is more attributeable to reefers' eyes getting used to the bulbs' colour than the bulb actually changing colour...I'll probably catch some crap for saying that but that's my opinion.
    I have my mh around 8 inches from the water as well and I don't change the height when changing bulbs.
    All the best to you, too!... there should be a santa smiley

    always more..........

    While we are on the m/h subject, how long will a 250W double ended HQI be good for? I have had mine about six months and was wondering when it would require replacing?

    Mine is situated 8" off the water also.
    We need more Indians!
