Battery Bank 24V My Big Costly Mistake!

OK I did it to myself by being complacent ,This will hurt me big time in the long run. What not to do, don't believe every thing U here is OK to do. So here I show what I did so U don't. I'm feeling pretty dumb right now but its to late. I wish I had taken some pictures of inside my battery in each cell every month. This is what it looks like as of today . I will update results soon.
