Lighting Question.

[pminister]

As an example I will use a single fixture as my question. Sorry for not using incorrect terms, for posing this question.

What will be the Pro's and Con's of using a single T8 vs a T5 light fixture for a planted tank ?

There isn't much difference between T5 and T8. However, T5HO (high output) will provide much more light.
