Papillon Alife 2550 is a mid sized ceramic CO2 diffusor intended for aquariums up to 250 lt.
It is made of acrylic body with a plastic cap which keeps the in place the repalceable ceramic disk via an O-ring.
My intervention was to add a similar acrylic non-return check valve just before the diffusor enabling to add a little water inside the body enhancing its use as a bubble counter as well.
It becomes a 3 in 1 CO2 diffusor, eliminating any more bulk inside or outside the aquarium.
Thank you for viewing.
