Welcome from Barrie, ON.
From your question you are going to get a ton of responses, so here is mine. I use a product from Thetford, they have a grey/black tank product and I also use their "Drain Valve Lubricant". Each of these products come in a 710ml bottle. You are going to become best friends with your local RV Dealers retail store as you will eventually need/want one of everything. Happy camping.
