The filter works well in my 80L tropical tank. Water clarity improved noticeably within a week. The carbon and zeolite layers help reduce odour and ammonia levels. Easy to install and fits perfectly inside the tank.
Claire Welch –
Good for small to medium tanks. The mechanical filtration catches debris well. I noticed a slight change in water colour after a few days, but it’s not a problem. The bio-screen seems to support bacterial growth.

Installed in my 100L goldfish tank. The filter runs quietly and keeps the water clean. The ammonia levels have dropped since using it. No leaks or issues after two months of use.
