Large hole in my lawn
 

Hi everyone.
I have a baby on the way so have decided to remove the pond from my lawn. It was quite large (8foot by 5foot and 3foot deep).

I now have a large hole in my lawn.

I am currently getting the patio replaced, so i have filled up 60% of the hole with broken up paving and loose material.

I have 2 options of how to finish this off:

1. Transplant some turf from an area that is about to be replaced by my new patio. This is very poor quality grass with 60% moss. It has been growing in a shaded area with poor drainage. This is why I chose to pave this section of my lawn. This would seem like the easy (and cheepest) option, but is it a good idea to move lawn ? and is it a good idea to use this as the quality is so poor.

2. Fill the hole up with soil and reseed/bye new lawn.
Can anyone tell me what I should be using to fill up the hole and to what depth above the rubble.

I suppose I've asked a few questions in there, but its my first time. thanks in advance for any advice you can give.
