Hey, I don't know if this is an issue with the Apollo firmware or the way that Prohashing issues work and switches coins, but figured I'd give you a heads up in case you or anyone else had ideas on how to solve.
TL;DR: When using Prohashing and having an active and failover pool enabled in my Apollo dash, I get high error rate, reducing hashing, and hash power going to active and failover pools simultaneously.
This is what I posted on their support forums, just speculating:
You can only use two or more pools, if they are both mining the same coin. If you use multipools, use only one (no failover). This is a bfgminer known problem.
