The process is called sublimation. Solids can turn directly into gases, and gases can turn directly into solid without ever being a liquid. Carbon dioxide (dry ice) is a commo â¦ n example of this. Other examples are mothballs, solid air fresheners (Air Wick), and iodine.
When you start itching from chlorine, get out of the pool and limit your exposure to the chemical. Chlorine-related rash and itching typically subsides within two to four weeks. Hydrocortisone creams help relieve the itchiness.
Re: How long should a 3 chlorine puck last? an 8oz trichlor puck will have approx 5.5ppm FC for a pool of 10,000 gallons. So it will just depend on how much FC loss you have day to day. This day to day demand may vary a bit based on weather, bather load, leaves, pollen, algae, etc. If you are replacing every other day that's almost 3ppm a day and perhaps on the high side, but it's going to depend on your pool.
