As long as pH stays stable, and other params are stable, is there as much of a need to do PWC's, except to replace trace minerals and such, in a berlin system?
I removed biowheels and turned off my HOB filter this week. Everything stayed stable.
At this time, I have no sponges or filters (except protein skimmer) anywhere in the system, except for one on the overflow, and I clean that regularly, once or even twice a day.
The water looks great - clearer than ever before.
I'm a little nervous about my next PWC though. That's always introduced a little ammonia in the system because of the chloromines. Not nearly as much since I've been using prime, but trace amounts are still surely there. I don't want to upset the system though, so I'll probably do very small changes at first.
RODI isn't in my budget. I usually use distilled water from the store for topping off.
How frequently do people using all natural filtration do PWC's, and how much? Does topping off introduce enough new water into the system to avoid frequent PWC?
