Okay, I am going out of town for a month and my marineland c-220 just stopped working. I have a small wet dry hooked up that s running but that alone is not enough filtration for my mata mata turtle and the other fish in with him. I need a quick fix (something that I can do this weekend) that will not break the bank. I was thinking a 20 long FW refugium that I could add a heater to as well as some java moss and maybe some inverts. what do you guys think?
