Water Testing for Swimming Pools & Spas

Water testing seems easy enough, but a few factors can seriously affect the accuracy of the test.  Following a few tips will help to ensure that your tests are accurate:

*  Water should be circulating before you take your sample.   If the system has been

          shut off, turn it on for a few minutes.

*  Rinse the sample vial 2 or 3 times with pool/spa water before you take your

          sample.  This eliminates any contamination from previous tests.

*  Sample the water from 18 inches below the surface.

*  Do not take samples near the return lines.  Water re-entering has just been filtered

  and may have been chlorinated.  It is different from the rest of the pool/spa water.

*  Water temperature should be between 60 & 80 degress F. 

*  Perform tests as soon as possible after taking the sample.

*  Carefully handle samples to be tested later.  Cap them tightly, and don't expose

   them to excessive temperatures or sunlight.

*  Make sure all reagents are fresh.  Replace reagents annually and store them

          tightly capped in a cool, dark place.   Be certain not to interchange caps on bottles

  of liquid reagent.

*  Carefully measure the sample of water to be tested.  Be certain water is on the

   fill line.

*  Don't interchange sample vials.

*  Follow directions carefully.  If 5 drops are called for -- add 5 drops.  No more and

  no less.

*  Add reagents by holding the bottle vertically above the sample vial and adding

  slowly.

*  Mix the test sample properly.  Use caps provided - not your fingers, which can

  contaminate the sample.  Never shake when mixing.  Always swirl in a circular

  motion or invert a few times.

*  Read results under the right conditions.  Hold the vial at eye level.  Look through

  the middle part of the sample against a white background or the back of the

  instruction card.  Don't wear sunglasses or read results in direct sunlight.

*  Don't dispose of completed test samples in pool or spa.  Rinse the sample vials

  well after testing.

*  Keep all chemicals and reagents out of the reach of children.
