I have one on a ten gallon and flow is not the best for that size but it is quiet and has been going for a few years now. Not bad for a cheapo one. Okay amount of room to place in different media or plants as well.
Just got it. The flow was a little too strong and began uprooting my HC. I took off the filter intake and stuffed it with filter floss and put some coco fiber in the water output to try to tame the current.
I hope it doesn't strain the filter too much but it was way out of control.
Maybe some bio sponge attached to the outlet instead? Never tried it or looked at the sponge so I'm not sure really, just an idea. But I love my quiet flows. Using two on my 20gal for more circulation. I've never used a cannister filter before so I prob just don't know what I'm missing out on haha
