I am running a penguin 350 filter system for my tank, it has slots for me to put 4 filters into it. How often should i clean or change these filters out? I am wondering if the best way to do it is to change/clean two at a time and leave the other two in there.
Also would running it under the sink or garden hose be ok to do since i still have two other filters in there during the process to keep good bacteria?
thanks
