Green Pool Recovery and Heavy Shock Treatment
Designed for neglected, uncirculated, or rain-spoiled pools that have turned into deep green or black ponds. We break algae blooms using high-strength oxidisers, flocculants, and non-copper algaecides, followed by vacuuming settled sediment straight to waste. We restore clear, swimmable water without draining the pool.

Why Pool Owners Choose ClearBasin
Fast, multi-stage remediation to turn black or green pools clear.
No basin drainage required
Draining in-ground pools risks hydrostatic pop-out and liner shrinkage; our chemical recovery preserves the existing water mass.
Complete spore eradication
We target phosphates and hidden spores in lights, steps, and pipework so the green bloom does not return two weeks later.
Equipment protection
By vacuuming heavy sediment directly to waste, we prevent your sand filter and circulation pump from clogging and overheating.
Our Workmanship Standard
If you notice water cloudiness or chemical imbalance within 48 hours of our scheduled valeting visit, we return to re-test and rectify the issue without any extra call-out charge. We stand behind our mechanical fittings with a twelve-month installation warranty. Pricing & payment
