Hi Vincent, Lam

Thank you very much for water aging lesson. Always have the wrong idea that water should be aged longer. Will keep in mind thay 3 days are maximum for water aging. What is the best way to clear the chlorine? Sunshine, heavy aeration using air pump or water pump, or any other ways. About the temperature shock, how to prevent it when doing water change? Sorry for asking these questions. They may already been explained during my visit. Just need to refresh my mind. Thanks.
