I measured and experimented, and have found the perfect proportions of CM and Water.
My Mya Acrylic needs 28 ounces of water, that's the perfect amount. I filled it with 20 ounces and added 8 ounces of CM and sloshed it around in order to mix it. This measurement DOES NOT bubble up into the stem and hose ports, a common problem with creamy base liquids. It will get close to the top but will never go over!
So subtract 8 ounces of water from your total amount and fill the space with coconut milk, mix it around.
Your total amount will vary, so i recommend experimenting, it's very fun when every pull you take looks like your breathing milk.
