Just want to double check on how to do this. I've had my current internal filter running for about three months now but I wanted to get an external one. Last week I bought a Tetratec Ex600 and have had it running alongside my old filter for a week. I know the bacteria won't have generated in the new one but wanted to get rid of the old so will take the filter media out of the old and put into the new....just wanted to check this is OK?
Thanks,
Andy
