So I am starting my first larger size tank 55 gal! Have two 10gal already cycled tanks and have been running good for awhile now. My question is I have shoved some filters pads in behind the ones in my cycled tank, any suggestions on how long to keep them in there. I have also grabbed some gravel and put it in two of the corners of the 55. I am really exicited about this tank and hope my fishless cycle does not take the 23 days my 10 did.
