I use an Aqua-Tech Power Filter 60 on my 20 gallon setup for my two turtles, the filter does a good job and i am happy with it. But there is a problem, you see its kind of hard to find filter cartridges for it. I usually get them in the fish section at Walmart. But days ago, my mom went and no luck at all. The guy actually told her that they are going to stop selling them.
So, i was thinking. Almost every where i go, i always see the whisper filter cartridges. They are even cheaper. Do you think i would be able to use those kind of cartridges on my filter, even though it is not from the same brand?
Help,
