I've been running 2x250W HQI MH lamps over my 125G for about a year now and it's about time to replace the bulbs. My lamps came with XM 250W 10000K HQI bulbs that have a very white-blue color to my eyes which is not bad but tends to wash colors out a bit. I've also used the ADA 250W 8000K HQI bulbs on a client's tank and definitely liked them very much. From what I've read the ADA MH bulbs seem to be the ultimate bulbs on the market but I'd like to get your opinions on what type of HQI MH bulbs you like the best. Thanks!
