The fish store I work at recently started selling this particular line of power filters...is anyone familiar with them? All the employees have been required to take them home and study them...take them apart, memorize parts lists, put them back together, and now we're having to test them out on our own tanks. Does anyone have any kind of opinion on these particular filters? Just from the short time I've had the one I'm having to test, I'm rather pleased with the results. The aquarium I'm running it on, a 29 gallon, seems to be altogether doing alot better since I've started running the Cascade filter on it. Does anyone else have experience with these filters? Have a different opinion or similar? I'm rather interested to hear what other people might have to say about this product.
