When deciding to go BB, I looked at tanks on RC that had starboard on them. I suspected detritus would get trapped under the starboard which would defeat the purpose of the BB. So I have my rock on the glass. Have reaquascaped several times since going BB almost 2 years ago and have had no problems with rock on glass.
To reduce algae problems in a new BB tank, cure your LR in something other than the display tank. Make sure you have a heater and lots of water flow in the curing container. Clean the rock of all dead and dying matter from time to time and siphon out the dead stuff every week or so. Once the LR has cured, swish it well in the curing container to remove as much detritus as possible before placing it in your display tank. You're good to go and without all the nitrate and phosphate build up that you left behind in the curing container
