Has anyone here actually built one, and how long have you had it? I am seriously considering building one this summer aprox 225 gallons. 72 x 24 x30. I have looked at the GARF plans and it seems easy enough and cost effecient. (Actually I am going to have help from "pro" carpenters and painters). But besides all the endorsements on the pages I would like to know how they hold up and if any maintenance is required to have it last for years to come.
