My filter is an Oase 100, but I may well just get a hang on tank filter too. Would I need to put it at the other end of the tank for best use?
I am really unsure about getting dwarf Cory's as I have purely gravel substrate. (What I have always used before in both 70's and 90's, never used sand. I did think about getting something like a ruler, but deeper, to portion off about a third of the tank, but am having difficulty finding anything suitable.
From what I gather on here most of you use it. When setting up my next tank I think I will try sand. How do you keep it clean??
