Hi,
I am using Eheim Substrat pro and I would like to know how often should I replace it with a new one? I just replaced mine after 9 months. Thanks.

I found the info here http://www.aquaticplantcentral.com/f...tml#post552337. Every 3 to 6 months according to the 2234 manual. Do you guys think it's OK to replaced it once a year?
Btw, $57.99 for 5L here: http://www.kensfish.com/eheimfiltermedia.html
