It was suggested I might be able to get some help in this section. I'm awaiting arrival of a new external filter (Tetratec EX700) for my 120L Juwel Reckord tank as the internal filter seems to be on it's last legs and I was hoping I could remove the old internal filter once the new filter was up, running and "started" biologically (whatever you call that
). I've had a little wiggle of the old filter to see how it's attached but it seems solid
could anyone tell me how they're removed? Is it possible with the tank full?
Thanks in advance
