Hey MadGerman, welcome to the forum.

What reflectors are you using for the 400w's?
 
Thanks Mekaeel, Yes it is the single ended ones I have got. I must say though having 1200w over the tank for 6 Hours (at the moment) causes huge temp increase. My chiller is working overtime. but well worth it.
 
Have seen some nice local set-ups with Marine-Lux bulbs ..............

Nice crisp white light with a tint of blue. But you do need to boost them with actinics
