It turned into an 18 hour a day, 7 days a week job and even though I was able to make a profit I finally gave it up from lack of time. [My husband threatened to go diving without me!!!] I've never tried Benghii but have heard that they are a lot easier because of they are larger to start with. I have a search out for a 40 gallon. I know someone that might be getting rid of one [upgrading]. I'll let you know. Donna
