I attached the Blue/White versions of this LED strip to the inside of the fixture: https://www.amazon.com/TrueLumen-Aq...rd_wg=XCgGQ&psc=1&refRID=K5G8FZHV8M9S8T1BGFNC
Bit late but here are the images I talked about. The shots are taken with only the main blues on and the supplemental white/blues on.
Here you can see the condensation under the hood.

Here is of the tank itself. It just got done with cycling still keeping the lights low till I can get my algae reactor setup.

I used 2 blue/white LED strips and they are connected to dimmer. For the shimmer itself I bet most is caused by the water rippling on the surface so a stronger pump might help. I'm not using the stock pump. I'm using a fluval 103 canister filter as my pump with the Hydor Flo rotating water deflector.
