I've been wondering about this, I bought my snail tank a T5 light setup but accidentally got a pink-colour Tropical light, but I have what is supposed to be a T8 Coldwater white light over my SFF & Shrimp tank, and the only thing I see wrong with them is that in my eyes the pink one looks awful!!! :p
I guess my question is, what is the actual difference between the two lights? And would the fish, shrimp & snails be adversly affected by them being the wrong way round?
Unfortunately I can't just swap them round as the T8 is way too big for the snailtank, and the T5 is probably too small for the other!!!
