4 in 1 Aquarium CO2 Diffuser Set
4 in 1 glass CO2 diffuser set including check valve, suction cups, and "U" pipe to connect over edge of aquarium. The composite material is inflexible, if your tank has an edge frame the "U" tube will most likely not fit.
All OK. THE diffuser is very small. Looks bigger in picture
Nice small diffuser, diffuses nicely
very good product and very fast delivery
