I think the 20k is not as intense but with a 35 gal
, you should be fine. I used to use 10k's with very little actinic. I am using 14k MH
with a 03
T5 and a Blue+ T5. When the Halides go out, the tank is VERY blue but the colors I get are amazing.
I really could not tell a huge difference with the CV 14k and the CV 10k. Some 20K are not super blue either. Just research the brand to see before you buy.
