Hey I have a 55G mbuna tank with tons of rock. It is filtered by a 2217 and a HOB, I recently removed the HOB and noticed that alot of poop has been accumulating in the front. I plan on adding a Koralia to help the water movement and surface film.
Which Koralia would be ideal for a 55G? I'm thinking of the 3, its $55 here. The 4 is $65 if it is worth it then I'll buy the 4 instead.
