Mmmm. Buffy....
Bevery had some nice tanks, although (not to belabour the point) I don't think any one of them did make it to 5 years. But, be that as it may, I don't think I know of anyone who was more anal about her weekly tank vaccuuming and water changes. She was right on top of that sort of thing. So I think she falls under the category of a "tank maintenance regime that compensates."
