Avoid. Tubes ended generating some white mold in one week!!!
Reviewed in Canada on August 27, 2021
I thought the product was good initially, and easy to setup, but after one week, the tubes started molding in the aquarium water, releasing some weird white goo, something that never happened with usual fish store brands. I had to discard the tubing completely, only keeping the extremities and the links.
Definitely would NOT recommend wasting money on this product. Possibly dangerous to fishes (some fishes got some fungus little after installing the product).
