Chemical Startup

Chemical Startup of a Newly Filled Pool

When adding chemicals, calculate the gallons of water in your pool and follow label directions for your pool type and size. Never mix different chemicals and always allow for complete circulation (at least one hour) before re-testing. Follow directions on your test kit or bring us a water sample for testing and analysis.

While pool is filling, add an anti-stain/scal product, such as Sparkle Conchelate per label directions for initial dose. Thereafter, apply maintenance dose, especially when adding water.

When pool is full and the pump and filter are operational, test pH and adjust between 7.4 and 7.6. An acid demand test will indicate how much acid is needed to lower pH. A base demand test will indicate the amount of soda ash needed to raise pH.

When pH is adjusted, superchlorinate or shock the pool using as much calcium hypochlorite as needed to raise the chlorine reading on your test kit to at least 3.0 ppm. Dissolve shock in a bucket of water and pour into pool. Wait 1 hour, then retest. Continue adding shock in this manner until the chlorine level reads 3.0 ppm. Never pour shock through the skimmer, as it gasifies quickly and may cause an explosion.

Run the pump and filter constantly for the first few days or until the water is crystal clear. Thereafter, at least 8-12 hours per day or as needed to maintain sparkling water.

Next day, re-adjust pH as needed, then add stabilizer/conditioner (cyanuric acid) slowly through the skimmer. After adding cyanuric acid, place tri-chlor tablets in the skimmer, floater or chlorinator as needed to maintain a constant chlorine reading of 1.5-2.0 ppm. Note: if you are using a Nature2 or Instant Frog mineral purifier, do NOT add stabilizer/conditioner.

Next day, add algaecide per label directions for a initial dose. Thereafter, use the maintenance dosage on a regular basis, especially after a heavy rain. If you are using the Natural Chemistry system, add Phos-Free Spring and Fall per label directions and thereafter, use the maintenance dosage on a regular basis.

Within the next few days, test and adjust total alkalinity and calcium hardness. Since many test kits do not include these tests, we would be happy to test your water sample and recommend treatment. Proper adjustmet is necessary to prevent pH instability, corrosion or scaling.

Test chlorine and pH daily. Maintain chlorine at 1.5 to 2.0 and superchlorinate to at least 3.0 occasionally or at the first sign of algae growth. Maintain pH between 7.4 and 7.6.
