Pros & Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

The ceramic media comes in a net/ mesh baggie which has to be cut open to use it in the u4. Unlike other media, perfectly reusable. I wish it was a little cheaper.

One box is more than enough to fill up the cartridge. This is the largest packaging of it that i have seen. Fluval has them available for sale as well, and they are available on amazon.

    Does the job been only 2 weeks and i already see some bacterial build up on the media


    Posted by a reviewer on Amazon

    Upgraded to this from bio balls this works much better for bacteria


    Posted by a reviewer on Amazon

    If fluval made these in a larger package volume i would buy that


    Posted by a reviewer on Amazon

    Make sure you only remove half your bio media when you clean or make changes in your filter so to make sure you maintain a decent established bacterial content in your tank to maintain a working cycle


    Posted by a reviewer on Amazon

    Dont wash or clean under the tap or the chlorinated water will kill off the good bacteria especially on the bio media you are keeping in the filter

    Fluval carbon 100gram nylon bags 3pack fluval zeocarb 150 gram 3pack nylon bags fluval ammonia remover 180gram nylon bags 3pack make sure you are buying the correct biomax bio media


    Posted by a reviewer on Amazon

    These are often mistakenly confused with the larger biomax bio rings which will not work or fit in the fluval u series underwater filters


    Posted by a reviewer on Amazon

    I am used to eheims effesubsrat but this seems to do just as well
