i could do with buying some extra bio media for my 2x fluval external filters, i know there is a few different brands and some cheaper than other but at the end of the day is the expensive stuff any better than the cheap stuff ?
seen this 'siporax' type on ebay quite cheap would it be any good ? http://cgi.ebay.co.uk/Breathing-Bio...14&_trkparms=72:1301|66:2|65:12|39:1|240:1318
