roscoe,
Sorry for not gettong to you sooner on this!
The Beetle 50 is made for large and very large aquariums. ADA designed them for and uses them on their 180cm tanks (180 gallons) and larger installations too. 200 + gallons, and the use of 2 diffuseres is advised, but depending on filtration/current in the tank, one large diffuser could certainly get the job done. I have a 240 hallon tank I run just one large (50mm) diffuser on without any CO2 issues.
The Beetle 50 could handle as high a bubble count as you would want to run, so there are no limitations there. It is more than sufficient for your 90 gallon tank. |
