I have a 92 gallon corner reef tank with 2 175watt 14k MH bulbs. One of the bulbs went out this evening. It would benefit me more to buy a new retrofit kit for a 400 watt bulb for 109.00 than to buy a new bulb locally for ~$85-90. Would the 400 setup be too much light for the tank? Do you think it would be enough since the bulbs are supposed to be only good for about a 2 foot square area? http://www.hellolights.com/index.asp...OD&ProdID=1775
Help asap would be greatfully helpful as I am down to only one bulb!!!!
Keep the 175's and get Iwasaki 15K bulbs. They perform better than many 250's. 1 400w is not a good setup for your tank.....unless you buy a Lumenbright type reflector and mount it about 2' above the water.
I found out this morning that my ballast and bulb are both bad. I need a new kit for the one bad side. I will be looking for a whole new setup because my other bulb needs replacing in Aug. anyway. Now the only question is to go with 2-175 or 2-250? What do you all think?
Very unusual for a MH ballast to go bad. 1 of mine has been in use everyday for over 20 yrs and it still works perfect.
If you want to buy 2 new ballasts, go with the 250's, but if you want to save some $ and use your good ballast, stick with 175's.
