I remember when I grew to 26 tanks...I came home from work one day and said I'm spending 4 hours a day cleaning my tanks...that's too much. 6 months to a year later I was down to 17, then the following year I was down to 5. I ended up down to 2 tanks when my newly wife said one was leaving the bedroom. I ended up as 1 as my base. Throughout the years I bounce back and forth up to 3 and 1... My tanks never looked this good though.
