Accidentally ordered the wrong replacement and don't know whether to get a new one or return the mistaken bulb for the right one.
Both sides are lit by a T5 420nm actinic. The left side is also lit by a 6,500k daylight and a 460nm actinic. The right side is also lit by a dual daylight 6,500k/10,000k.
Just looking to see what other people thought before I made a decision either way. Thanks!
Ps: don't freak out over Pacus in a 75, I am growing them out for someone who has a much larger tank! :thumb:
