I have 300 w MH with 2-21w T5 blues on my 80 gal DT. The tank looks yellowish form the MH. Could I add more blue PC light to tone the yellow down? Would that work?
Thanks in advance.

Yes, MH do have a color rateing know as kelvin ( K rateing ) if it low around 6500K then thats very yellowish but best for growth and can be offset useing PCs or T5s ect. that are actinic blue and the more you use the blueer everything looks. You can buy MHs up to a 20000K rateing and they have much more blue already in them and other lights may not be needed if turn out to be the color you like.
