An excellent filter
I had a cloudy aquarium with a filter priced 400 rs. It had to run for a week to make the water clear and the water flow was strong which made the fish hard to swim on their own. But this filter does magic. With in some hours after installation, the water became crystal clear. The flow is very smooth too.

Good, not great
Underwhelming. Had read a lot of great reviews. But not delighted. Good design, no doubt. Easy to install, clean etc. Powerful motor. U3 working well in a 25 Gallon In my opinion, filter media volume is just too small. Mechanical filtration is inadequate and bio media is too small in volume. Sponge filter choked up in a week and when I pulled the tray out it spilled a lot of muck back into the water. Again, good product, but not great.

Great product
It's a great product. Since the time I have used this filter my aquarium lasts almost a month without changing the water but the only problem I faced was that the clip on the stand which holds the filter broke within 2 months and as such the filter has lost its balance. I hope there was a way to fix this.
