Great filter

This filter was good for my indoor tank while I had my turtle, after getting the water cycle good, it was about to keep up with turtle waste with 20-40% water changes

works well, rinse before use.

using these for years, changing 1x a month. easier for me to just rinse new ones and replace rather than messing with own filter floss etc. pay for the convenience

Too large.

I always buy large filters for my fish tank. And this one was too large, but I got it to fit anyway.
