For a small tank, the watts per gal
rule don't work. You need more wpg
to get to an equivalent light level compared to a large tank.
over a 10 gal
will not be too great for plants. Depending on the light (some are more efficient than others), 2-3 wpg
is what you should be aiming for (A high light tank will have 5-6 wpg
). <I used to have a 33W T12 fluorescent over a 10, and that is only low to med level.>
A glass top will definitely give you the most options. You can hang fixtures from the ceiling, or attach them to the rim with legs. And you are not tied to any aquarium fixture, as an ordinary fixture (with the right spectrum bulb) will work as well.
