I bought the Outer Orbit 150 x 2 HQI with 4 T5's and my question is how good are the Current brand buldbs and should I replace them?I have had the tank up and running for about 4 months with the new light and wondering if th Current brand quality was less than other name brand bulbs..they are 2 460's and 2 420's actinics... What brands are suggested and should I swap them out sooner than later ??Thanks Sal
