Hi everyone, got a question for you. I recieved my new (2nd hand) filter today, it's come from a heathy well established marine tank. The bacteria is still alive and I was wondering if I could use straight away on my new tropical tank. I not is it safe to transfer my mature media from my fluval 3 to the new tetratec ex1200 and then add the stock from my old tank to the new one straight away ?


maybe try a few bits and see. but obviously the sponges will melt at that temp.....
