T5NO will work fine on a 40 breeder
<---- Were you speaking of this guy? :tongue:Still around pepperonihead?
I am back to reconsidering T5NO vs T5HO for my 40 breeder as new circumstances may suggest that I use a canopy instead of an open top or egg-crate with raised lights. With the canopy I will have little or no room to play with, height wise, so i can't make adjustments that might be necessary for a T5HO setup. I've seen beautiful 40B tanks with a 2 bulb T5HO fixture (speedie, etc) but don't think that was their first experience with a heavily planted tank.
I do have CO2 and EI ferts, wouldn't want to waste them but the rig and ferts also will last forever so i don't need to go crazy with lighting etc in my first attempt at the "planted tank" side of the hobby (my 20-high has like 15 plants in it with 2 bulb T5NO).
I am thinking of a custom 2 bulb T5NO with the lights spread out maybe 10" apart from each other. However this seems to me like it will be really low lighting (Hoppy's chart lists single bulb T5NO as low or "---" for a 16" deep tank) - because of the spread of the bulbs I am unsure if many areas of the tank will truly experience 2x-T5NO light. Is 2 x 2-bulb (4 total bulbs) T5NO an option here or would that be too high light now?
