Hang on power filter or internal power filter

[stickitywit]

Im going to be setting a 15 gallon soon and i cant decide on which one to use. I have never given internal power filters much thought before. I have always had success with hang on power filters, im considering the cascade power filter by penn plaxx i believe. The only internal power filter i know about is from tetratec, anyone with experience on internal power filters. I usually dont stock so high because i travel and im gone for days at a time, rest of the family only knows how to feed them and top off with water.

If you've had good results with the HOB and are away for days at a time i'd stick with the HOB's, since you know what you'll be getting for your money, how they operate, etc

I've always used the hang on external power filters and think they're great and easy to maintain, not that there is anything wrong with other types of filters. It's a matter of preference and functionality. If it works for you go for it. You might want to try one with a bio-wheel.

A couple of years ago I took the plunge and got an external cannister filter. Best thing I have ever done.

If you can afford it they are worth considering. I sometimes find eggs, danio fry and swordtail fry in mine as well.

As far as internal filters go, why take up valuable space with equipment if you don't have to

For a 15gal tank a nice HOB bio-wheel would be all you need. A 15gal isnt that big of a tank so theres no reason to waste space with an internal filter. A Penguin/Emperor bio-wheel mini is rated for 20gal and is reasonably cheap.
