How do you make there be no dead spots when you stack the rocks right up against the back glass?
Does flow still get back there?
Should I even be worried about this?
I am asking because when I set up my current tank, someone said something about deadspots being behind my rocks that when disturbed could spike things in my tank. I have a PH
buried behind all of the rocks in my tank right now and i don't have any problems, but I don't know what would have happened if I didn't have it back there.....
I think I read something about sitting the rocks on PVC
or something, but I don't really quite remember what it was talking about.....
Any thoughts, suggestions or comments on this potential problem?
Thanks in advance for any help!~
