I don’t think I’ve ever seen a HOB trickle filter. Definitely not one like that!

They're much more popular in Japan. They're based off of the same idea as a bakki shower filter used in many high end koi ponds. I've never used one but I like the way they look if you want to display filtration. Here they are in Amazon: AE SHOP Aquarium Canister Fish Tank Filter Cartridge for 3.4-3.9 Feet Tank, Clear https://www.amazon.com/dp/B01JA77XH6/ref=cm_sw_r_cp_apa_Ol6kBbG4TKP7H
