Im using an Eheim 2215 on my 72 gal. Should I keep the spraybar near the surface, or drop it down ? It seems to be pretty forceful, so I was also thinking of extending it to reduce the pressure. Any thoughts, comments, suggestions ?
If it's creating a lot of surface turbulance, drop
it lower - but if it starts blwoing plants around,
you can enlarge the holes slightly. Keep in mind, once
you enlarge the holes there's no going back. If you over
do it - you'll probably have to get a replacement.
