Thanks monkiboy.. I am a bit flustered here.. Pump is working fine this am but my MP60s are not, they are working off the backup batteries. I am wondering if it is the APEX acting up or an overload on the APEX. I did add an 800 w heater and maybe that is causing issues with APEX and electrical. I am no good when it comes to electricity.. I will be trying to get hold of APEX. Thanks.. and I do enjoy very much sharing on RC as I learn a lot from RC, although the past few days have been taxing my emotional personality, from fish death, ich then now pump issues APEX issues etc..
