You are correct. Those temperatures are air temps. I never really thought about the differences in water temperatures as it relates to air temperatures....hmmmmmm thanks for the clarification. Yet another thing to research...Do koi mind that 5-6 degree change? In the wild, I'm thinking they will have temperature swings based on depth of water. Aloha.
