An Experimental Comparison of Sandbed and Plenum-Based Systems http://www.advancedaquarist.com/2005/6/aafeature http://www.advancedaquarist.com/2005/7/aafeature Cliff notes: - plenum: does not add value - deep vs shallow sandbed: shallow (2.5cm) had twice as many deaths as deep (9.0cm) - coarse vs fine sand: coarse was slightly better |
