Hey Bev... Cool info.
Not sure it's do-able for me.
I guess it would be. Sounds super-easy. But I am sure I'd call it a chore after a few weeks, or months of 3-times-a-week cleaning.
Plus when the weather warms up, I'll probably spend more time in the... garden!
A real nice fish tank - this is another story. I'm thinking about getting one. I always enjoyed looking at all different fish in the tank...
