:scratch: Mr. Dawson and Olaf: I am just getting back into aquariums after a very long sabbatical. I received a nice 55 gal tank at Xmas, w/ power head and bio-wheel filter. After the 45 day break-in, I decided I wanted scats and mono's. The guy at the LFS told me how easy they are and to set up for the brackish, I'd only need to add sea salt at 1 tbs / 5 gallons. WHAT A CROCK THAT WAS! After losing 3 mono's ( the LFS replaced 2) I figured something had to be wrong. I awoke this am to find #4 and last Mono struggling on the bottom. The others died over night so I couldn't see what type of distress they were in. I jumped on the Net, and found this discusion forum and you guys. Thank God! I read through several of your communications and surmmized there was probably low salt in the tank. I drove to town, got a hydrometer and more salt, a test kit, etc. Low and behold, the SG in the tank was "1.000"! With Mono almost gone [ others seemingly doing well, silvers, greens and sabae] I started adding salt to a SG of 1.005. Buy golly the Mono perked and started swimming around. The others got more rambunctious too. Like a shot of steroids. I guess the FS guys are in it for the $$$, certainly not a credible resource for info. Thanks to you both!
