Thanks for sharing that video. Awesome.
I've found that European LFS - particularly German LFS really are "museum" exhibits of sorts. Korallen/Coral husbandry is taken to a whole new level of passion and science.
I've spent many of my pre and post Oktoberfest itinerary visting various LFS in the past. This LFS store was definitely one of the standouts.
The "Triton Method of Filtration" is based on this LFS's (Triton Korallen/Triton Reef) methods and experimentation for Coral husbandry. Well beyond my body of knowledge. You can perform an online search and decide which side of the fence you sit on.
