Too much water in my mash! Problem?

[scarer]

Hi

I'm brewing a Mild today but I've used too much water in my mash.

The recipe calls for 9 litres but I used 16 litres confusing it with another recipe.

The grain bill is 3750g and the recipe calls for the mash to be 63C for 90 mins which I have done.

Will this extra water cause me a problem?

I'm going to be fly sparging shortly......

Thanks

Great, thank you
