Hey Everyone, I wanted to get some opinions on bulbs. I have a current usa 48" 2x250W-MH, 4xT5 hood, with a M138 pulse start ballast. I am looking to replace my bulbs, just the MH bulbs. I currently have 2 14K pacific 250W-MH bulbs. I like the look it gives the tank, but they seem very bright. I want a more blueish look to my tank, but not too blue. I was wondering if anyone can give me some suggestions on what bulbs will give me a high ppfd and blueish tint to the tank,..based on the type of ballast I have. Opinions are appreciated.
