I had my 12g gallon tank set up for 3 weeks. First week I was adding Seachem stability to speed up the cycle. Water parameters after 3 weeks are zero so i went out and bought 7 mini rasboras. After 3 days two have died. I also have maxi-jet 400 110 gph. Is that too much for the little fish? If i have the maxi-jet pointed and the face of the glass and it creates too much current for the fish so i have the deflector 90' up. Still the fish don't really rest and keep swimming in the current. not sure if they hate it or like it. I also have 7 shrimp in there and they are doing well.
