Did my tank crash! Help!

[Sasq40]

I had to drive the wife to work so I didn't get a chance to mess around with it. I'm going to have to get some salt water made cuz I just did a water change yesterday. Either going to get a dosing system for my kalkwasser, or selling the tank I don't think I can handle a crash, and my wife won't let me spend all that money again if it is :-(
