The three photos show Brian’s Anoxic Filter in the UK and just after a few weeks now how the plant growth is progressing. Just a few years ago hobbyist thought that all aquatic plants needed fertilizer tabs in the form of high nitrogen to accomplish good plant growth. To this day these fertilizer nitrogen tabs are being sold under the supposition that their use is vital if success is to be accomplished with aquatic plants. For container gardening yes, but for pond or aquarium use nothing could be further from the truth.
However, today hobbyist know better, or at least they should know better, than to use any fertilizers in their ponds and/or aquariums. Fertilizers of any kind help accelerate the eutrophication of the aquarium and pond by these artificial substances and therefore increasing unwanted nutrients. These added nutrients will then have a negative effect on the aquatic system but may also have an unpredictable growth on plants and algae. This in turn may need evasive action by the hobbyist to eradicate such insults, like green water or high nitrogen levels leading to cyanobacteria.
Beautiful lush green plant growth can be easily obtainable with the right knowhow and ammonium/ammonia. The plants must find the ammonia ion somehow and that is just what the BCB’s accomplish in one of their many functions.
The Anoxic Filter, though it can be hidden from on lookers, looks better in the open than hidden away in some darks corner somewhere in the yard like conventional filtration is. It gives hobbyist the opportunity to do two hobbies at once. Water gardening and Koi or Goldfish keeping at the same time. Combining the two hobbies give people the opportunity to enjoy Koi without sacrificing the plants because of their foraging nature.
