Well I have not had experience with MH
lighting but I do know that they are expensive and give off a large amount of heat. So you will have to keep a close eye on your water temperature. I've heard that you should replace the bulbs every six months, but Im not quite sher about that.
However I use Power Compact lighting. Not quite as natureal as MH
but is more than exceptional lighting. Its a lot cheaper than MH
. Doesn't give off as much heat as MH
. The bulbs have also been said to last a year without replacing them. Honestlly the only difference I see is that the MH
gives of the images of riples in the water. A lot of people use power compact. I wouldn't trade it.
