[GSAS-Member] Using Actinic/Blue Lights in Freshwater

[<carrera206@comcast.net>]

Thanks for all the responses.

Clay- What exactly is your light config? Are you using the 10000K lights and
if so what is the color cast (I think it is a bluish white)? It sounded like
you used the 10000K or 10000K/Deep Blue combo lights with a 6700K or 5000K
light. Is this correct?

I am currently using the AH supply retrofit kit 4 x 96 watt CF bulbs. One
pair of 5000K and one pair of 6700K. I run the lights on a cycle of the pair
of 5000K lights turning on for 5 hrs or so and the pair of 6700K lights
taking over for another 5 hours with some overlap with all 4 of the lights
on for 0.5 hrs or so. I like the change that occurs with the different
lights but although the CRI is quite high with the 5000K & 6700K lights I
wondered if the 10000K or lights might make the fish look better. I tend to
like a bluer light despite my having pretty white lights now.

I am thinking that the dawn to dusk effect of using a set of 1000K/Deep Blue
lights for 3 hours switching to the 6700K lights for 5 then back to the
1000K/Deep Blue lights will achieve this. What do you think?

I don't have a lot of plants other than annubus and a couple of java fern,
but they do not grow much. I believe that I don't have enough CO2 in the
water because of my wet/dry trickle filter and my main interest is the fish.

Thanks again,

Al
