Genuine Aqua One Spare Parts
This Aqua One 404s sponge is perfect for trapping debris and hence is very good at nitrifying filtration bacteria. It can be cleaned by rinsing it in some aquarium water only. If the cell structure of the foam starts to collapse you are advised to replace it.
We recommend only using Aqua One genuine spare parts in the Aquis 1050 / 1250 range of Aquariums.
