Why is my hot tub water cloudy?

Cloudy water could be caused by a number of factors, namely:

  • Inadequate filtration/dirty filter  – Increase filtration Cycle duration if used heavily. Clean or replace filter as necessary
  • Excessive oils/organic matter: use  Shock spa with Sanitiser
  • Suspended particles Run jets and clean Filter; Use a Clarifier
  • High total dissolved solids (TDS) Depending on severity, drain spa to half full and refill or completely drain and refill.
