Claiming is not "proving"they claim
I have a 200L 100CM tank- would 1 be enough? As I say I was a bit disappointed with the 'spread' of light on the Chihiros and the light is very 'white'. I'm redoing my tank with a view to keeping Dwarf Rainbowfish and was thinking the this may give off a 'nicer' light. I have planted some Rotala so bright light is necessary.
