I discussed this briefly in another thread, but I'm particularly interested in the location of the compressor, and how it affects temperature. Here's my theory: A pump or air compressor pulls in air around it, and directs it to your diffuser. If the surrounding air is 95°F, theoretically, your pump is directing 95° air into your pond. Those little 95-degree air bubbles will heat up the surrounding water as they travel to the surface. Also, the pump itself is creating heat, which could potentially cause 100°+ air to be sent to your pond. If your pump is in direct sunlight, that could exacerbate the problem even more, versus keeping it in a shady location. Is there any merit to this "theory" of mine, or does the temperature of the air bubbles not matter as much as I think they might?
