See, mine was all backed up so I popped the lid and pumped it out. But I'm looking at that thing and thinking that with a little hot water it would be kind if fun. You know, get some chick in there with me. Ya know. So what's the best way to clean all that brown s*** off the bottom and walls. And how do I plug up the line into it so when somebody flushes a toilet it doesn't go into my new spa?
