So. I followed your advice and checked out my gfo. When all of this started i changed out my gfo, and the valve must have gotten set to wide open when i slipped it back behind the tank, so essentially my tank has been filled with gfo for the last two days. I placed on filter socks and filter floss before my return pump stopped the gfo and replaced the carbon. My foxface is the only one that i could find through the brown murky water and he was looking next to death. Ive got him in a qt and hes looking better. As for my other fish i have no idea how to find and rescue them. Anything else i can do? Since i dont have enough on hand, Im going to get some sw from the lfs and do a water change, ill test and get you some parameters as soon as i get the water change done. This has turned into a massive disaster. You have no idea how much i appreciate your help
