Also 5 mono's, 2 chromides, a figure 8 and an archer.. but my salinity is currently at low to 0. I've been adding 1tsp per gallon. How many tsp's per gallon are you adding to reach your desired salinity levels?
hehe, tsp/gallon? No idea. I'd buy the bucket of Instant Ocean and after a water change I'd take 5-10 gallons out at a time and saturate the older water with the salt mix and would add that to the tank. I repeated the process until I got the desired saline level which could be as low as 1.012 and as high as 1.020.
The wonderful thing about brackish fish is that they are HARDY! Think about it, during a 24 hour period, these fish can go from fresh to full sea strength according to the tide schedule. So I developed a water change system for them that would introduce FW while I'd simutaneosly remove the old water and clean the gravel. The fish would LOVE it! You could see them swim in the new water.
Then when I added the salt to the tank, they would have a similar reaction. The sharks would actually drink/swallow the saltier water... interesting.
You will definately want to raise your salt lvl for the Scats. Mine were much more prone to diseases when the levels were low, but after 1.015, they were extremely healthy. They have small gills compared to their size and they "breath" heavy in relation to the other fish. And so I could gage the quality of the water and the oxygen lvl, just by looking at how hard or fast they were "breathing". (The same with eels.)
