I used the 501 filter on the 20Long I had Pickle in when she was a baby. It's really not worth it, it's an awful little filter in my opinion. Not only is it very underpowered for a turtle tank, it's constructed poorly. It was hard to even open and close, and next to impossible to get primed. It was always clogging and stopping and making horrible sounds.
I never had the fluval 4+, I suspect it's a better product. I have the BIG fluval and it's awesome. If I were you I would spend the extra $10, I think you will be happier, even if it is only temporary.
