my light looks dim yet my plants are growing incredibly fast.
A bulb with a different kelvin rating would probably help then. What is the kelvin rating? How old is the bulb? They get dim when they get old and algae problems start occurring.
I will probably upgrade the entire light
If you upgrade get a Corlife light strip at Pet Blvd
. The bulb goes all the way to the end of the strip. I chose Pet Blvd for bulb replacements for my coralife for they have good reviews.
