Fluval Mini Underwater Filter, 200 Litre Per Hour

Delivered much sooner than expected good filter not too noisy happy fish happy owner.

Great for a small tank, using it in a 25 litre tank. Its quiet - make sure you put the out spout 1cm under water. Really seems to clean it without swooshing the fish all over the place - my previous filter was so powerful if shifted the sand at the bottom of the tank. This one seems gentle for small fish, but still cleans. Easy to take apart and rinse the filter material in the old water during a water change. For the price its good value and would recommend.

Fair little, simple internal filter. It does what it says. I read a review slating it as the box says for 45l tank and they were expecting 200l tank from the listing. User error in that case I'm afraid; the listing quite clearly states 200l/hour turnover, suitable for a 45l tank. So cycling the volume of the tank just under 4.5x an hour.Anyway, my observations after 6 months of running on a 40l guppy tank:It has a moderately powerful flow rate, which I find ideal for raising Guppies, but more sedate fish will find it too fast, I definately wouldn't use it with a Betta.It's silent in running after it's primed itself and access to the impeller is quite easy for cleaning.There aren't any options for flow control (direction or flow), but it is a very basic unit.The supplied sponge is realistically too small for the canister and allows too much detritus to flow around it, allowing the impeller to clog, or worse stall. I've rotated the sponge 90 degrees to fill the bottom of the canister and placed some filter floss above it and some bio-media on top of that. This has kept my tank water much clearer.The bottom loading of the filter media can become a bit of a chore. The lower suction cup invariably dislocates itself from the unit when pulling it out for cleaning, but for what it is and the price I can forgive the primitiveness of the design.I originally bought it as a stop gap after my old unit died & haven't felt the need to upgrade as it works, even if it is a tad fiddly.I can't give it full marks, as I've had to modify the filtration system and feel like eventually the bottom panel (where you access the media) will fail.

I have this in my 55L tank, and it does a great job. It's extremely quiet! I recommend this filter if you have a small tank, and need something that doesn't sound like a jet engine!!Very easy to use and clean. Simply take it out of the water after unplugging and then take the top end off. Remove the sponge from the bottom and give it a good clean. Pop it back in, all done.It creates a nice gentle flow in the water which is perfect for my Fancy Goldfish. She doesn't like strong currents, so this is perfect.I came back to buy a second filter because my goldfish is so damn messy! So now I have two running in my 55L tank and it's still much more quiet than the filter that came with the tank.Highly recommend if you want a silent filter that actually is silent. Obviously at night you will hear a faint buzzing, but still better than the sound of a jet engine ;)

This works really well but as another reviewer said way too strong output for betta - a shame you can’t turn flow down .. easy to clean.. I’m now using as a second filter in a bigger tank which is fine

Very pleased with this excellent little filter from Fluvial. It does the job perfectly and is so quiet that sometimes I don't believe it's running. Water flow is great and is ideal for the smaller aquarium. I'm very pleased with this filter and the price is good too, have seen it in local retail shops at a more expensive price.

Easy to install great size for a small tank well made not noisy good value for money

I put this in my 80L tank. That’s right you heard me. And, it works a treat. I purchased some cumbersome filter for £20 off amazon which broke within 2 months and this little filter has much better suction than that and doesn’t look unsightly. I don’t mind about having a large filter but I took a punt on this one working in my larger tank and it seems to have paid off as the water remains crystal clear. My only gripe is the price. It’s a tiny bit of kit for the money and should be sub £15 in my opinion. But you pay for the name and the reliability. Fingers crossed this filter continues to do a great job.

Très bon produit bonne filtration attention prévoir un adaptateur u.e pour la prise

Great product, but it was sent with a U.K. power plug and not Australian, so I had to buy an adapter to be able to use it.
