That is what we use in all the boats and my 5er Don't just pour it in the water tank unless you can drain it all out. Don't let it sit in your hwh either. Some of our customers let it sit in all summer and it is GROSS stinks something aweful. You won't have any problems if you keep it out of the tank and hwh. It almost seems like it rots/decomposes if it gets a bunch of air to it. It will keep stuff from freezing and bursting though.
