Is my lighting OK?
Set up my first tank and decided from the start to go with real plants. I want to get some opinion on whether the setup is ok.
I have a 20G high acrylic tank. It came with a single 15" 14W T8 6700K light. I've added a fixture that holds 2 24" 14W T5 6700K lights. They are on top of the tank (molded acrylic top underneath the dual light - nothing between water and light for shorter fixture). Using excel for carbon. heavily planted.
*EDIT - I'd say the lights are about 14-15" from the substrate
A few questions:
1. Is the lighting enough?
2. Is it positioned correctly?
3. Will the acrylic top mess with the light under the dual fixture (absorb some of the light, etc)?
