THE TANK HAS BEEN ESTABLISHED FOR 4 MONTHS. THERE IS NO HEATER(BESIDES INDOOR ABIENT HEAT) AND THE BALANCE OF THE WATER WE'VE MAINTAINED WITH THE VALUES FROM THE BAY-AMON-.25,NITRATE-O,PH-7.5,ALK-0,NITRITE-.05,TEMP-68-75 DEGREES. THE FISH ARE SUNFISH,BLUEGILLS, SHEEPHEADS,SHINER,SPOT CROAKER,WHITE BASS,GRASS SHRIMP,GOBIES AND A BULLHEAD CATFISH. WE HAVE PICKED UP ICK IN THE CROAKER AND BASS. HAVE TREATED FOR TWO TREATMENTS BY INSTRUCTIONS, CUTTING IN HALF FOR THE CATFISH HEALTH AND LIVE PLANTS. THE SALT IN THE TANK IS KEPT AT 2-TSP PER 10GL. PROBLEM WE STILL HAVE SOME ICK, THOUGH IMPROVED, BUT THE CATFISH HAS CHANGED FROM A BLACK TO A REDISH TONE. SO WE'VE STOPPED THE TREATMENT, WHAT NEXT? CAROVA 2010-12-05
