I've actually had that light. They are awesome lights! 👌 all depends on how far you have it about your aquarium. What size aquarium? I'd aim for 6 inches above the aquarium and little over half power on the blue. Also, turn the white on to about 2 maybe 3. Hopefully this helps you

Also, only turn the light on for 9 hours

@CoreyDeMerchant got it thank you brother helps a lot running at 60% blue and 20% white , light is actually on top of the aquarium lid actually sitting on it and aquarium is about 20 inch deep so its not that shallow
