Hi everyone
I've just managed to get hold of a used Fluval 205 external filter, which I intend to use in my 110 lure Juwel tank.
What should I do initially to prepare the new-yet-used filter, and how do I go about removing the built-in Juwel filter without destroying my tank?
Also, on a side note, if my heater okay to simply be against the wall of the tank? Will it harm my fish if they get too close?
