The new Google community is already showing its advantages with others and me communicating on an easier level, example shown below. Please take a look-see at Michael Lim’s pond. However, if you have a jealous bone in your body then don’t look.
Michael, to say your photos are impressive would be an understatement. Your pond and its layout look as though they belong in a public conservatory somewhere. Very clean and crystal clear water.
I think your methods of applying the BCB’s into your system in the old none working veggie filter is spot on! Season the BCB’s before you wean off of your existing system is a prudent move.
Your aquarium photo looks as though it is a breeder’s tank much like Dr. Franco did in Italy. Maybe some tropical fish lovers out there will employ this same method of filtration as you have.
Did you use clay or Zeolite as your medium choice? What were your Nitrates before the introducing of the BCB(s) in you aquarium?
