I clean my nautilus tanks with hot water, when I change the coil throw the used one away. When you go onto building make sure you read and know Ohms Law to ensure your builds are safe. I build my coils to .8 up to 1.5 and love the added flavor they can produce. Am going to purchase a Atlantis to see if they produce more flaver not for the clouds.
Good info Steve! and thanks for addressing one of my questions. If you try the atlantis, let me know what you think.
