Need advice 60” T5 over 48” tank

[lzkamp28]

I decided to downsize to an 80 gallon tank (48x24x16) from a 120 (60x18x24) . I’m loving how easy it is to clean due to its shallowness.

I have an aquatic life hybrid fixture 60” that has 4 80watt bulbs in it. I currently have it 12” above the water.

How can I have success without investing in a new fixture? Should I add two more T5 bulbs in the center, or leave it as is?

I would think your coverage will be good without adding more bulbs.
