Test your stabiliser level before adding more, you may already be in range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need stabiliser in a spa pool?\u003c\/strong\u003e\u003cbr\u003eA: No, cyanuric acid is not recommended for spa pools. The higher water temperatures and smaller volume make over-stabilisation a risk. Use unstabilised chlorine in spas.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I know if my stabiliser level is too high?\u003c\/strong\u003e\u003cbr\u003eA: Above 80 ppm, chlorine becomes less effective even at correct levels. The only fix is to partially drain and refill with fresh water to dilute the cyanuric acid.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often do I need to add stabiliser?\u003c\/strong\u003e\u003cbr\u003eA: Cyanuric acid is very stable and only lost through water loss (backwashing, splash-out, rain overflow). Test monthly and top up as needed, most pools only need 1-2 treatments per season.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this safe for saltwater pools?\u003c\/strong\u003e\u003cbr\u003eA: Yes, saltwater pools benefit greatly from stabiliser as the chlorine produced by the salt cell is unstabilised and highly susceptible to UV breakdown.
