I don't think I've ever bought ATI bulbs. Mostly KZ and I always got good deals on them from REd Coral or Concepts. The only problem with KZ is that they were always hard to source. Concepts has solved that now I think but for a time I couldn't find KZ bulbs
Instead I used a "SuperBlue" bulb from some other manufacturer. I think it was AquaWave or something like that. That looked pretty good too for a non-actinic high blue bulb. It was probably closer to 22K though than 20K.
Anyway, I bring it up because you only have 4 bulbs to play with and if it were me I would want to maximize PAR out of the 4 bulbs. Putting in 2 actinics cuts your PAR virtually right in half immediately leaving you with just two T5 grow lights.
edit: I'm not sure how much PAR the fiji puts out as I don't have much experience or research on them. I had them over my tank once and hated the fiji purple so never used them again.
