    Bonding and grounding are two very different things that are often confused. Grounding serves two purposes. First, a ground conductor provides a low resistance path to conduct lightning strikes to the earth. Second, grounding provides a low resistance path for hot wire shorts to conduct enough power back to the main panel to trip the circuit breaker. Bonding is about making sure that any electrical current that is present around the pool goes through the bonding wire instead of going through you.

    Welcome to the visual encyclopedia of pool equipment, a collection of photos of many common pieces of pool equipment and supplies. Many more photos, of items that were not included here, are available in the submissions to the contest that started the visual encyclopedia, here.

    Here is a list of commonly used abbreviations, acronyms and terms that you might run across.

    Algae doesn't need to be the bane of your existence. The simplest way to get rid of algae is never to get it in the first place. If you maintain the appropriate free chlorine (FC) level at all times, algae will never be able to get started.

    The earlier you catch algae, the easier it is to get rid of. When algae is just starting, the water will have a dull appearance and the FC level will start falling more quickly than usual. If you catch algae at this point, it usually only takes a single application of chlorine to wipe it out.

    TFPC stands for Trouble Free Pool Care. What else is TFPC? Simply put it is just good pool maintenance using bleach (liquid chlorine) and other generic chemicals that are readily available at the grocery store that are EXACTLY the same as the expensive ones from the pool store, along with water testing with a GOOD test kit so you know WHAT you need in your water and HOW MUCH you need to add.

    If you're about ready to post and ask some questions, you will first need to help us and yourself by getting some basics out of the way.

    Please put the city and state in which you live in your profile. Your climate is important to the advice you receive.

    Please put the following information in your signature.

    • The size of your pool in gallons
    • If your pool is an AG (above ground) or IG (in ground)
    • If it's IG, tell us if it's vinyl, plaster/pebble, or fiberglass
    • The type of filter you have (sand, DE, cartridge) and, if you know, the brand and model of the filter.
    • If you know, please tell us the brand and model of the pump, and mention if is it a two speed or variable speed pump.
    • Date of pool build/install, particularly important if less then a year old.
    • What kind/model of water test kit you are using
    • Other significant accessories or options, such as a spa , SWG, or cleaner
    • Please mention if you fill the pool from a well or are currently on water restrictions

    PoolMath,, is a handy web-based tool that does all of the calculations required to maintain your pool. PoolMath can figure out the amounts of chemicals to add, what appropriate FC levels are for your CYA level, what your calcite saturation index is, and help you estimate your pool volume. It is also possible to make a local copy of the PoolMath web page, and use it without an Internet connection.
