Cheers Brian QUOTE: “Your Lilly's have came on great I've just got leaves on mine at the moment how many plants is that for that much coverage filter is looking lovely mate makes me want to build my Anoxic Filter bigger.”

Brian Woodcock’s Anoxic Filter after four weeks. The two, yes that’s right, just two water lilies have taken up most of the filters top available growing surface area.

The succeeding photo shows just how high/big Yellow Iris can grow and become root-bound in a BCB. They may become so big and creates such a vast vascular root system in just on season that they will split the BCB’s (Biocenosis Clarification Basket). All this without any fertilizer tabs, just let the plant do what comes natural and utilize the Ammonia ion like they are suppose to.
