Well.. decided to build a new scrubber so i could fully contain the light and use better lighting. All black acrylic. Went with a 14" long x 9" tall screen (55 clownfish + 28 BTA's) feed twice a day. 2 x 20w IP65 LED floodlight per side. Had to use 1" PVC for a frame to hang the scrubber over my sump, bottom will be 1/4" above sump level.
Went with this design from basically looking at 100's of scrubber boxes online:
