good. I'm giving it five stars because it produces really wonderful little bubbles. On the other hand, I would like to give ZERO stars for Hydor's COMPLETE lack of recommended tank sizes for this product. I would also like to give it THREE stars for terrible air handling. You seem to need a much better air control valve for this thing, not this little twisted cap with a piece of sponge inside. I bought this for my 36 gallons. Even on the LOWEST setting, the microbubbles completely filled my tank and stressed my fish into hiding. I might buy an air control valve myself to see if I can really reduce the bubbles. main filter - canister). I took the bubble generator out of the aquarium and said: c'est la vie! What size tank would I recommend for this thing? 55 gallons or more. When I get around to setting up my 55 I'll add this to the tank. This will absolutely do the job of oxygenating the water! And beautiful at the same time!
