Fluval Aquaria, per stuk verpakt (1 x 4000 g)

Works good so far.

dont know if it do its job because after 3 weeks of use they are so dirty they wont let any water through. there are cheaper ways to lower phosphates

Well first of all I ordered what I thought was NITRATE pads and they are actually nitrite pads. So I put them in and when I had maintenance done today discovered my error. However my LFS guy said that it was actually doing what it was supposed to even though my tank didn’t need it and wouldn’t benefit from it. So we took them out but it is a good pad to use if you are looking to lower nitrites in your tank and is designed specifically for Fluval Flex and some other Fluval models. Small and easy to just put in your filtering chamber and does remove nitrites quickly.

Works ok
