I have a mixed 125g reef. Light source is 72" T5 fixture with 2 10K, 2 ATI aquablue special, 2 ATI coral plus, & 6 actinic. I'm wondering if I can cover the tank or if covering it will affect the light spectrum that gets through? The T5's don't heat it up much, but the evaporation loss is still 1/2 to 1 gal
a day so if I can cover some sections with acrylic sheets it would help. Thanks in advance for info.
