I had another older model which seemed to be doing its job, but when I added the new aquatop, how obvious the differences. I put the older powerhead in my 'save in case of emergency box' for that day you wished you wouldn't have tossed it out :^). I notice my African Cichlids like to swim in the stream like a workout and then hit the calmer parts to graze & play. I would recommend upgrading & don't forget to get a sponge on the end. Really helps with keeping things tidy.
This works great and adding a filter sponge to it makes it fry safe too!
My favorite brand of powerhead. Works great and lasts.
Love everything I’ve bought
