- Check the safety fences, gates and self-closing devices.
- Brush & vacuum the pool.
- Check & clean skimmer boxes, lint pots, filter, pump and all equipment/accessories and ensure that they are all operating properly and safely.

If there is no visible presence of algae, and the pool is sanitized by:

- Chlorine - "superchlorinate" the pool to bring it up to a concentration of free chlorine of about 10mg/L.

- Salt Water Chlorinator - "superchlorinate" with sodium hypochlorite solution or potassium monpersulphate, or check the salt level and operate the chlorinator and filter for at least 24hr.

If algae is visible in the pool, "shock dose" the pool to ensure a concentration of free chlorine of about 10 to 15 mg/L, and then, for 2 or 3 days later add a chorine-compatible algaecide.

Continue to brush, vacuum and adjust and monitor over 3 or 4 days, so that the water is chemically balanced, and returns to a "free chlorine" level of 1.5 - 2 mg/L

Check that the following are within the recommended operational range:

- Total Alkalinity 60 - 200 ppm

- pH 7.2 - 7.6, and

- Calcium hardness 0 - 500 ppm.

The pool is now ready for use, and the normal routines specified by the builder can be resumed.
