I'm not sure what the deal is. I keep my alk around 9-10 dkh. You might want to raise it a bit. Also, it appears to be in a different location than the first pic. Maybe you should move it back to where it was doing good.
Thats exactly what i did and in the process bit bit about 25 times by my damn maroon clown, fiesty lil bugger he is, glad he dont have teeth.
