BAITAI Internal UV Fish Tank Filter,400L/H 4W Aquarium Filter Pump,Turns Green Water to Clear,5-in-1 Filter Pump for 15-80L Aquarium,Flow Rate and Direction Adjustable

Best product I’ve bought its has improved my water quality in the tank big time I was getting green cloudy water evey other week till I got this ok it may have taken a week or two but the water is so clear and clean.

Really impressed. The small filter fits behind my 34l Fluval Flex. The motor on the Fluval tank gave out so I’ve kept the original media at the back of the tank and installed this. It’s powerful and does a great job.

Great when it worked for flow ans size, but after about 6 weeks it would randomly stop. Then work. Then stop. Its dead now, just over 8 weeks into having it.

Cleared my tank in 7 days after a bacterial bloom, water is now completely clear! Size is standard, not too big for my tank. Noise level is standard. Easy to assemble.

The BAITAI internal UV fish tank filter is very effective, it circulates water at 400L/H and helps keep my aquarium clean and clear. The 4W UV function works well to reduce algae and bacteria, and it runs quietly without disturbing the fish. Compact, easy to install, and reliable, a great choice for maintaining a healthy tank environment.

Filter is quiet and does the job perfectly, only reason for the reduced stars is that the little contraption to control the airflow came cracked. It is quite large (I'm not super fond of how bulky it looks in the tank), but is creating a relatively calm water flow, great for my 40L beta tank. Very easy to disassemble and clean too.

Great filter! Fish tank has been clear ever since we put it in, haven’t had any issues with green water since, worth the money for sure!! Would deffo recommend,

Bought this as I have already have a UV filter in my pond which have proven very effective and thought I would get one for aquarium. This unit is working and filtering the aquarium water very well keeping tank crystal clear. However, I would not purchase again and now question my choice as replacement 4W UV bulbs seem to be unavailable so once UV bulb fails will have to purchase a different unit. As others have mentioned there is no visible indication to show UV is working and instructions poor. Addition to above. I have been using this filter for six months now, it has kept the tank crystal clear and I have not had to clean the glass at all. Initially I was concerned that replacement UV lamp could not be found but, from this supplier I have been able to purchase a replacement. I have now purchased another of these filters for a different aquarium and that is working well. When I remove the unit to clean the sponge I turn it on for a second without looking directly at the lamp and can see that it is working.
