Organic carbon dosing, biopellets, macro algae refugiums, cryptic refugiums, mangroves, deep sand beds, algae turf scrubbers, zeolit, live rock, sulfur denitrifier, wet/dry trickle filter, under gravel filter, protein skimmer, denitrification reactors, granular ferric oxide, phos down, praying to Poseidon... do we really need another method? I've yet to see anyone empty an all tridanca clam refugium. So I guess there might be that.
