I finally decided to go back to scrubbing, I remember being successful on my 40 breed tank years ago and now I implemented to my 120.
I made the box a little longer to accommodate Herbie style overflow and I'm glad I did it was quiet. LED has 6 Deep Red 660 nm and 2 Hyper Violet 430 nm. Screen size is a little smaller than 8 x 6 and mounted on the inside of 40 breeder trim
So its a two sided light, i will add potentiometer to contol intensity to not shock the fresh screen for the next 6 weeks until screen is fully mature. Running light for 9 hrs for now
