I have a Current Outer Orbit that I'm thinking of using for a 58g that I'm setting up. It has two 150w HQI's and 4 39w T5's. The HQI's are 10k, the T5's are Currents 460nm and 420nm(basically blue and actinic). So if I was to choose to replace either the T5's or the HQI's first, which would give me the bigger bang for the buck? I'm assuming the T5's since the 420nm are pretty much worthless and I've heard that Current's HQI bulbs aren't too bad. Is that the general consensus? I was going to replace the T5's with all ATI Blue Pluses.
