I am running 14k hamilton 400 watt its on a 40 breeder. If i go to a 20k will it cut down the intensity of the light. I am loseing a little color on the sps.
They are just getting liter the green monti was a deep green now it is a lime green the pink one was hot pink now it is lite pink. It still has full plop.
and if this is the case, yes changing the light to a 20k (which means less PAR, less intensity) colors will get more intese (deeper) but thats not the best solution,
less duration of photo period
a bit more feeding
raising the light
