I have the reefkeeper 2 and recently purchased 2 BRS 1.1ml/minute dosing pumps for 2 part. My first pump I put in channel 6 on the multitimer and the second doser on channel 8. I have not had any issues with channel 8 working but channel 6 came on one night and according the the dispaly shut off at the appropriate time. However, when I looked at the pump it was still running. Any ideas on this, why was it still recieving power?
