Keeping your pool clean, safe to use and free of nasty germs takes some complex chemistry - but how can you tell if your pool service is properly qualified and experienced enough to use your pool chemicals safely and economically? Luckily it's very simple. Before you contract a new pool cleaner, ask to see their ISPE membership certificate (see below) and make sure they are a full member. A full member will have a certificate like this one. It demonstrates the holder is both qualified and experienced. To qualify for full membership your must be over the age of 30 and have had a minimum of seven years in a reasonably technical and responsible position within the swimming pool industry. Don't think twice or accept excuses - your family, friends and any good pool man will be pleased you asked.
