You may already be doing this but if not it's a good idea to keep the water and food dishes on a slate or a large tile on top of the coir so it doesn't get trailed into the dishes by their feet. The only real down side of coir is those long hairs, apart from that it's great. I mix it in one of those garden rubber bucket things (trugg is it?) and my wife once added the water and put in far too much and it was like soup
