Added a Poll
By popular demand, I posted a poll for selecting the size limit of a nano freshwater tank. I used 20L and 60P tanks as the 1st level, 12L tanks as level 2, standard 10 gallon as 3rd cut off and standard 5.5 gallon as level 4. Don't think I have the option to post another poll for pico so, someone else would have to compose that question. Please vote everybody.
