...but ive been away from these boards and marine tanks for 2 years...and back then there was lots of talk about pleniums (sp?) are those popular anymore? i am now very familiar with the DSB/BB argument, and not starting a fight...just wonder why no one talks about them anymore.

Plenilums are touched on from time to time, most people just went with DSB insted though because it is difficult to setup a plenilum correctally, and it is very important to set them up right.
