Not at all, one could run an algae trough, an algae turf scrubber, an algae based fuge, or a DSB
, none of which require LR
, and all of which provide biofiltration. Even a shallow SB provides a significant amount of biofiltration, and all of them provide some method of removal for nitrates. Granted, as X pointed out, they are all more effective when combined with LR
