So been really diving deep into this hobby. This Red Sea tank I received from my family doesn’t have a serial number, but it looks similar to red sea’s e-170. I have a question for any tech savvy people. This seal / gasket broke off the back and is now leaking water preventing the tank from filtering dirty water. Here is the part in question. And if anyone knows where I can get a replacement / do a fix on it, I would appreciate it. And so would my corals.
