Watching a video of a public aquarium in Columbia and they use large sand filters. All the public aquariums use sand filters for the last century. So,how did it become they were never adapted to the large home aquariums or Koi ponds? What's with all that trickle filter,floating media,plastic scrubbers?
Planted tanks with very few fish,i know a canister is good enough. But so many people are out there with 100 gallons and much more of Cichlids and a big sand filter would handle that easy. None are sold for the home.
