Acrylic vs glass lighting?

I just upgraded from a glass 45g tall to an acrylic 85g flat hex back. I'm using the same lights as before, a 36in coralife retrofit kit with 2 96W bulbs (10,000K and Actinic). The acrylic tank seems twice as bright as the glass. Both have a canopy, but the glass was an open water, and the acrylic has cutouts.

Anyone else notice something similar?

You definitely get better clarity through acrylic than through standard glass, but I'm surprised the difference seems that great. Are the lights the same height above water?

I have never noticed a yellow tinge from an acrylic tank. My best guess is either they are not cleaning the acyclic properly or you are seeing the true color of the water and then need to add carbon or ozone.

I made a similar observation when I moved to acrylic from standard glass. My halides seem seemed twice as bright on my new 450 acrylic compared to my old 215 standard glass aquarium.

Then kudos to your great husbandry if you never need to use carbon or ozone.

Really, I am surprised you didn’t notice any difference with ozone. I used it for one week and it honestly didn’t look like any water was in my tank. The tank water became so clear that it looked empty except for the floating fish. My tank is setup as a room divider / peninsula so clear water is very noticeable.
