Pictures never do a tank justice. Especially when lighting is concerned.
That being said, from the pics I actually prefer the look of the T5s. I myself am making the opposite transition. I have an 150w HQI over my 40 breeder and I'm switching to 6 T5HO tubes.
Halides have the shimmer, and give depth to a tank with their shadow effect...that part I love. However the quality of light and their sheer versatility, T5s have won me over. With the multitude of available bulbs its easier to find the perfect combination to get *just* the right look for your tastes. AND...you won't need a chiller.
If I have a much larger tank (Say, the next tank I plan to build, a 120 gallon) I think I would go back to halides, but I think I would still supplement with T5s. Have you tried the combo yet?
I would be interested to see others' opinions on the topic. Who else has tried both? Which do you prefer?
