I have had luck with turning off the heater and using paraguard. Currently fighting it in my PFR tank that I just revived. I might try what Lex suggested and dose with Maracyn II next week once after a big water change if things don't improve.
Just reporting in. Paraguard and lower temps seem to be working again. The shrimp I pulled from the tank in a hospital Tupperware container is doing well. After an hour long paraguard treatment at 3x the dose he has been getting fresh water changes consisting of tank water treated with paraguard. His limbs appear to be less brittle, the cloudiness has gone away slightly, he is moving around again and this morning there was a fresh molt.
Paraguard and lowering temps help out. I think I got the bacterial infection because I just added new shrimp to the tank and changed around the lighting. I went from 13w daylight bulbs on my 10g to two 23w daylight bulbs with added tinfoil lining, which caused a huge rise in my tank temps when the heater was on. I unplugged my heater and the shrimp all seem happier and there are no more cloudy brittle looking shrimp in my tank. Still going to treat paraguard for one more day. This treatment has been going on for about two weeks but only really took off when I noticed the hot tank temps and pulled the heater.
