I am freaking out, lost nearly all my fish most of the coral snails and inverts, great looking pair of cleaner shrimp. The temp was down to 73 and all smelled like death. My G/f and I did a 20 gallon water change (on 90) and cleaned up as best we could and added a sock of carbon. I do know if this doesn't pull out I will be selling everything as I can not afford to bring it back to where I had it again, I am tapped out when it comes to the fish tank. I really want to try and prevent selling it so.... Any help and suggestions would be great to help things along, there are all kinds of worms floating everywhere and tons of other things. Some corals seem to still be alive but hard to tell right now. Again any help or thoughts would be very helpful. I am just sick!!!!
