Why pools go green
The chlorine dropped away
Hot weather, heavy rain or a big weekend of swimmers burns sanitiser off faster than the chlorinator can replace it. Algae only needs a day or two of that.
The system stopped running
A timer knocked off, a tripped circuit, or a pump switched off over winter and forgotten. Water that isn't circulating is water that goes green.
Something has failed
A worn cell, a blocked or channelled filter, or a pump that isn't pulling properly. The chemistry can't hold if the equipment isn't doing its job.
Which of the three it is changes what the pool needs. That's why we test the water and check the equipment before anything gets tipped in — otherwise you're buying chemical to fix a mechanical problem, and it'll be green again in a fortnight.
What a recovery involves
Test and inspect
A full water test plus a look at the pump, filter and chlorinator, so we're treating the actual cause.
Treat and circulate
The right dose for your pool's volume, then the filtration running properly to clear it.
Vacuum and balance
Dead algae vacuumed out, water rebalanced, and the filter cleaned so it doesn't come straight back.
How long it takes depends on how far gone the pool is and what shape the equipment is in. Ring us and describe it — or send a photo — and we'll give you a straight answer before we come out.
Before and after
Send us a photo of it.
Ring the shop and tell us what the pool is doing. We cover Dapto and out to Wollongong, Albion Park, Shellharbour and Kiama.
