Hi Christo
Have you had the T5's on yet? Are you happy with the Zetlight/T5 combo?
I've just started with a 2.200 X 65 X 55 with two 6600 and was considering to also place T5's next to the Zetlights. My thoughts where to only have two tubes per light as my tank width is 65cm but I see that you have four tubes per light and I must say it looks impressive. Will only be doing the upgrade when my tank is a bit more mature but what are your thoughts on a similar setup like yours on a 65cm wide tank?
Regards Tief
