Natty, if you feel the tank is bad. Which I had a simikiar issue about 10 years ago.
1. Go talk to where you purchased it.
2. Call the manufacturer, send them pics, explain problem calmly but let them know it is stocked.
I had similiar issue, Retailer ordered new tank in with manufacturers approval. I bought several rubbermaid tubs and in 1 day emptied tank into tubs, returned tank, brought home new tank, replumbed (better then the first time) and restocked. With zero problems to livestock. I have moved a tank the same way.
This was a 125. I know it was a pain but I felt much better knowing the tank was secure...Hope this helps, Maybe if you have a local club, someone can loan you tubs, cnas and buckets to house inhabitants during transfer...Good Luck..
