BioSmart Flow Filter 18000

I have tried a few filters now for my pond and this one is by far the best. I did upgrade the UV filter as well which helped but my water clarity and quality have never been so good. It's easy to do a quick clean every week or so(using the easy to use cleaning system) but still needs a good clean every couple of month or so by taking the sponges off and cleaning them by hand. Would recommend

After 10 years of having my Koi pool, I finally have clear water. Although the pond is roughly 1700 litres I was told to double the size of the filter box due to the amount of Koi I have. Even on a sunny day the water remains clear. A good UV light (seperately) also helps.

So far so good. Easy to clean. First filter I have had so hard to compare but the brand was recommended by others that have maintained a pond for years

Good quality, cleaning is extremely easy, does a great job, clears water quickly, paired with 36w UV lamp, was easy to install, so far I love it.

water is starting to clear, filter works well

great shame no uv.

It's been installed now for 4 weeks and water is very clear now. Time will tell if a five star rating rating is warranted. Very easy to set up and water flow rate has also improved when a pontec air pump was installed. I have one air stone in the filter and another in the pond. As a result the fish are feeding more and are happy.

The description was not detailed enough, this is gravity fed and needs to be positioned above the highest point. Didn't come with instructions on how to put together. I returned this.
