Frugal alternative to Marina i25 filter?

katholicos

Hiya, looking for any info about any frugal alternative to purchasing filters for our Marina i25 pump/filter thingy. Was wondering if anyone else has tried purchasing the filter material and replacing that rather than purchasing new cartridges for it? Thanks in advance for any help.

Just cleaned the filter and realised that i am going to have to bite the bullet and purchase the replacement filters. I know, i am just a cheapskate for wanting to find a frugal alternative!

I find ebay is the cheapest source for the filters.

Having removed the filter cartridge i now realise that they have been designed in such a way as they have to be replaced with more or less, the exact make and model of filter. I did manage to find some fairly reasonably priced filters on fleabay, but in true tightwad mode, i'm still a bit narked i can't replace them more frugally!
