    Big help
  

*by S***H on Reviewed in the United Kingdom on 29 September 2019*

I got rid of my gavel in the fish tank and I found this kit.And I feel that the tank is better off.I kept the inner circle too, so big circle I do not push to the bottom of the tank i let it keep a gap.So excess food and waste can walk down the outside of the tank still and go into the inner circle filter.To me a lot better.

Although this is intended for using different media such as gravel or fancy stone, you should stick with BioOrbs ceramic media as it’s part of the biological filter medium which houses the beneficial bacteria for breaking down waste.I purchased this purely to stop baby molly fry from getting underneath the filter intake. This will also stop the fear of smaller fish from getting down there too.

Quite expensive for what is essentially just a piece of foam but it does enable you to use a wider range of gravel in your biorb rather than the ceramic media that you're instructed to use.
