My first tank was a 10 gallon Metaframe, Xmas 1970. My dad made a cover out of screenwire for me. I saved my allowance and got the dual incandescent light stainless steel cover. Next I got a state of the art undergravel filter. I saved more and got a used 5. Fast forward via my DeLorean with Flux Capacitor and I have about 800 gallons in water now. When I am done getting over this surgery, I will put my 700 together.
