LO N SLO 1 KG DOYBAG BIOGUARD
High pH is the quiet efficiency killer in pool chemistry. Your chlorine is in range, your alkalinity is fine, and yet the water has that flat, dull quality and you're burning through more chemical than you should. Check the pH.

Your sanitiser suddenly starts doing its job properly. Chlorine at pH 8.0 is 78% ineffective. At pH 7.4 it operates at near-full capacity. Dropping pH from 8.0 to 7.4 doesn't feel like much on a test strip — but it's the difference between chlorine that's working for you and chlorine you're essentially wasting. LO N SLO moves you from the first to the second.
Scale and tile-line build-up stops forming. High pH drives calcium out of solution — creating the grey scale on tile lines and the milky suspended haze in the water. Correct pH keeps calcium dissolved and your water clear, your tile lines clean, your pool looking the way it should.
You handle pH correction without risk. Liquid hydrochloric acid is used in pools across South Africa every day — and every day someone burns their skin, ruins their clothes, or stores it unsafely near children. LO N SLO delivers identical pH correction as dry granular acid — zero fumes, zero spillage risk, measurable and safe dosing every time.
BioGuard gradual correction formula. Designed to lower pH incrementally — protecting against the overcorrection into acidic territory that creates the exact opposite problem you started with.
High pH is the quiet efficiency killer in pool chemistry. Your chlorine is in range, your alkalinity is fine, and yet the water has that flat, dull quality and you're burning through more chemical than you should. Check the pH. If it's above 7.8 — and in Pretoria pools that see a lot of bather activity and product additions, it often is — LO N SLO is the straightforward correction. The pool that holds its chemistry correctly is the pool that costs less to run, looks better all season, and never produces the kind of water problem that has you cancelling a Saturday. Get the pH right — and keep it there.
