I am about to buy some new t5 bulbs for my 2 dual 36" 21w coralife fixtures.
the old ones on there were one 10k and one actinic on each. i didnt get to see it when they were still working so i still dont know the difference.
i was told actinic had the most blue, and that i should get 1 21w 10k and 1 21w deepwater on each fixture.
whats a good combo?
this is goin on my 125g
