Aquael Neo Filter 300

The intake slots are wide enough that my guppy fry don't get sucked in, and cleaning takes just a couple minutes. Water flow adjusted easily with the dial, so my small tank stays crystal clear without chilling the fish.

I’ve been running this filter for a few weeks now and the mechanical filtration is noticeably crisp—debris gets trapped fast. The internal panel design fits neatly behind the aquarium hood, leaving more swimming room for my fish.

The filter's compact size was exactly what I needed for my 20-gallon tank, and I’m surprised how quiet it runs—barely a hum even at full flow. Water clarity improved noticeably within a few hours of installing it.
