I have a fully cycled saltwater tank and want to start adding critters. I have (at least) 3 questions:
1. I used Galveston Bay water and it is nice and clear running 7,500 ppm
salt, but I keep getting brown fungus or something adhereing to the tank walls and shells in the tank. Any idea of what this is and how to minimize or get rid of it?
2. I am using a cartride filter and fabric bio filter. Will this be adequate in a 5 gal SW
3. I want to add (at first) baby crabs, baby stingrays, and baby shrimp that I can get out of the surf. I figure the crabs will eat almost anything, but what should I feed baby stingrays and shrimp?
Any help would be appreciaited.
