Very good diffusers, great aeration, fully adjustable flow, good size, easy to fit , great value, silent in use.

Great product I have a 120 litre tank and they work a dream , very happy fish too

Good air diffusers producing a nice stream off bubbles

Excellent air diffuser

Would have given this 5 stars, but the sucker is useless.

The diffuser produce a fantastic cone of small bubbles.seem to produce a much larger bubble stream than airstones.I think the is less resistance than from a stone so less wasted pump output.lots of surface turbulence with a feint hissing rather than the loud popping noise.they also work great at a depth of 45cm.ä which impeded the output of my airstones.

Fianće says that these are great and they work perfectly

Great product and fast delivery

These Fluval air pump diffusers have been performing exactly as expected and have been a great addition to my aquarium setup. They produce a consistent stream of fine bubbles that provide good aeration without being overly aggressive. Installation was quick and straightforward, and the adjustable flow control makes it easy to dial in the right amount of air for the tank. Once positioned, they stay in place and continue running reliably. Build quality feels solid, and they’ve been operating smoothly with no issues. There’s nothing flashy about them, which is actually a plus — they’re dependable pieces of aquarium equipment that do their job well. If you’re looking for simple, effective aeration with reliable performance, these diffusers are a great option.

Work great definitely my favorite aerator

This is a permanent air stone. It is also adjustable. The bubbles are a mix of ultra fine and small air stone size. Works really well. Arrived in excellent condition and quickly.

This is a lot simpler than using air stones. It has great pressure. Even in a 24 inch high tank, the bubbles are stirring up the surface well enough that I needed to adjust the output so that the lid wasn't getting soaked. Great product.
