for sale bargain Eheim internal filter foam just the foam. they fit from a size 2006 2008 2010 2012 you can cut them to fit and if you have small ones you can use the offcuts to get extra ones I think 2 offcuts make a 2008 filter foam size. they are around £10 for a small pack and around £18 for the 2012 size so these will save you around £55 upwards maybe over that. I used to buy bulk when I kept fish but don't have any now so they will save someone some money. I have put a photo of them in a bag and a photo of a filter they fir the filter is not for sale I don't have one call after 3 pm and my phone won't let withheld numbers though.
