Are you replacing the filters? If so that's a no no. I couldn't tell by what you were saying if you bought a new filter and swapped it our or not. But you want to basically never replace your filters as that's where a vast majority of your good bacteria live.... use it until it's falling apart.. even then stick another good one in there to seed it before a total swap.
Other than that just keep up the PWC's and keep testing. You're doing a great thing IMO rather than letting everything die.
