    Do not change the filter!! It is the same trap I fell into when I started up my first tanks. You think you are being a good fish keeper and then all of a sudden your fish start dying. When you replace the filter, you are taking all the good bacteria out of the aquarium. There is no reason to replace a filter unless it is falling apart. It it is absolutely filthy, rinse it in syphoned water from your tank, not tap water. You will cause a disaster by changing it. If you run both at the same time, it is going to take a long time for the new filter to colonize, and a few days would not do it.

    What kind of a filter do you have, it just says power?:pokey:

    Yeah, don't change the filter media. You are pretty much just wasting money. If the media is very filthy and restricting the water's flow, just rinse it in a bucket with aquarium water.
