It looks like you are using 8 "bulbs". Question is, what size of tank, or better, how did you calculate the number of "bulbs" needed based on the size of your tank?
Thank you

Hi my fish tank is a 29 gallon. I held one light bulb over the aquarium and just imagined the x amount of light it will produce if I put x amount of bulbs.
