Alternative to Eheim "MECH" and "SubstratPRO" Media?

Hi guys,
anyone using an alternative to Eheim "MECH" and "SubstratPRO" Media in their Eheim filters? Ive a 2180 and filling it with the Eheims own-brand media is going to be crippling. Are there any other good medias that are out there?

Seachem Matrix is quite a bit cheaper than Eheim media as is lava rock from Home Depot or Lowes. You can also find pumice in varying sizes relatively inexpensively online.

Ill have a look for Pumice on the amazon.co.uk site - that could be a go-er

Nowt on Amazon.co.uk BUT did find this http://www.specialistaggregates.com/...el-p-1540.html Might look into this one :-)

What sort of size should I be looking at? Found a good european site http://www.gardenorchids-shop.com/Su...Pumice-gravel/

Im guessing the 8-16mm sized gravel would be the best size? Or is that too small even? If its the right size then 25 Liters of the stuff is going to cost 19Euro including delivery - or 16..less than the price of a Pizza @-)

Well, larger sized pieces are going to allow for faster flow through the media while smaller, of course, will slow down the flow, but allow for better mechanical filtration. Seachem's site says Matrix is about 10mm in diameter. That would be an average since some pieces are a bit smaller and some a little larger. ADA's Bio Rio, which is a volcanic rock, is quite a bit smaller than Matrix, probably less than half the size of Matrix. I just mentioned those two for comparison sake. The size you've mentioned would work well also, IMO.
