Very good aquarium filter. Also clears cloudy tanks in 24 to 48 hours

It does what it’s supposed to, but I find it rather loud and will probably send it back. For a smaller aquarium it’s probably fine, but for a larger one where you have to set the regulator higher… it gets louder.

Great for my little 40‑litre aquarium. It’s 👍👍 quiet
