• Pool chlorine and pH levels: what to aim for and how to correct them

  Aim for free chlorine of about 1 to 3 ppm (Saltmate's chlorinator manual) and a pH of 7.2 to 7.6 (Saltmate and Pool Pro). Correct total alkalinity first, then pH, then chlorine. Logan City Council's licensed-pool standard (pH 7.2 to 7.8, free chlorine at least 1.0 mg/L) is a useful Queensland benchmark.

• How to fix a green pool (and why it keeps coming back)

  A green pool is an algae bloom, usually caused by free chlorine falling too low. To fix it, get the pump and filter running, brush every surface, bring pH to 7.2 to 7.6, shock with chlorine to the product label and filter continuously until the water is clear, then retest before anyone swims.

• Salt chlorinator not working: how to find the cause and what to check first

  Most salt chlorinators stop making chlorine because of low salt, scale on the cell, poor flow, or water chemistry such as low stabiliser, which lets sunlight break chlorine down faster than the cell makes it. Owners can test the water, check flow and clean the cell by the manual. Power faults, fuses and worn cells need a technician or licensed electrician.

• Salt vs chlorine pool: how they differ and which suits a subtropical backyard

  Both are chlorine pools. A salt chlorinator makes chlorine on site from dissolved salt, while a traditional pool is dosed by hand with liquid, granular or tablet chlorine. Salt cuts routine chlorine handling but adds a cell, acid for rising pH and corrosion care; hand dosing has simpler equipment but needs a steady routine.
