I am running 2 sol blues also. Why will you be switching back? I have been having some issues with colors. I have been thinking of supplementing with t5
I have 2 tanks running and the parameters are almost dead even in both tanks. No matter what I take from the tank with the LED's and put it in the T5 tank the colors look 10x better. Stuff that has been in there for almost 3 years responds better to the T5's and anything that goes from the T5 to the LED gets washed out and closes up. The Par meter shows almost identical pars at where the corals are placed, but never the same results from one tank to the other. Also I have noticed the SPS grows about 4x faster under T5 for me and all the chalices grow better under them as well. ESV salt is used in both tanks and comes from the same batch when I make water for the water change.
over my 40b 3 maxspcet mazarra ps and 20long has 2 orphek pr25s.. leds have giving me better color and growth. i think with the leds it comes down to what guts and are inside makes the light.
