I plan to not add more fish to my fish system unless upgrade past a 300 gallon fish tank or bigger in that I have four Goldfish in a 75 and they started out two inches long and are now eight inches long and I've had two of them in their for five years.
I emailed another aylic company and they told me the costs of several supersized aylic sheets
The first sheet was a 10 foot wide by six foot high three and a half inch thick sheet at that came out to $20,000 dollars and a 14 foot long eight foot high four inch sheet came out to $41,000 dollars. So I think eight foot by four foot high will be about the upper limits of any super sized tanks I might try in the future unless I win the Lotto Pick 5 or Megamillions or get a $100,000 dollar a year job.
