im new to the hobby i have a 300l tank with a tetratec 1200 external filter its been running about 4 months .i have now bought a second hand eheim pro 2 2028 with all the media used but good condition ive just washed it thougherly with lank water it gleaming lol its now been sitting there for about a week till my eheim tubing arrives through the post just wondered what the process was to install it ??do i have both filters running at the same time till the bacteria builds up in the eheim ?or do i turn off old filter completely and put a little bit of the old media in my new filter does that make sense please help
