:confused2:Got a 200 gal tank at the house I keep bait in. Got a 600 gph pump with a 5 gallon bucket filter with AMMO CARB, poly and a sponge filter. Also got 4 six inch air stones putting air in it. Bream are still dying, anybody got any suggestions on something else I could do. Checked on bait today and its got a strong odorl to it, may be from ones dying but hadnt had this problem before. Water temp is only about 70 degrees.
