Chlorine Does NOT Play Nice with Others.

Remember to never store other chemicals (cleaning products, solvents, fertilizers, deicing agents, etc)  in pool filter or pump rooms.  The most widely used pool chemical is chlorine and it does not play well with others (particularly ammonia compounds).  Very bad  things can happen if they should mix, including creation of chlorine gas and other highly toxic substances.  Ammonia is present in most fertilizers and a number of chemical deicers.  Stay safe this summer and separate your chemicals!
