I am still learning about my new tank, but I did buy it used so there may be some things I am learning the hard way. I was just looking at the website and noticed something in the picture of the rear sump area that I did not get with it. I have circled it in red. Maybe it was an option the guy did not purchase or just did not give me during the sale. So what is it? Before I purchased the optional sump it was running fine without what this is.
