ULTRA CHLOR 5 KG WATERWELL
When a pool needs serious recovery, you need a product that doesn't negotiate. High-strength, fast-acting, built for the moment when gradual won't do it. ULTRA CHLOR is calcium hypochlorite at the concentration that pool technicians reach for when a pool needs to come back from the edge — and at 5 k

The pool that went wrong on Wednesday is swim-ready by Saturday. At shock-dose concentration, ULTRA CHLOR breaks down algae cell walls and destroys bacterial contamination in a single aggressive treatment. Not three days of gradual improvement — a hard, fast reset that gives you back the weekend. Discover the problem midweek, treat that night, vacuum, re-balance, swim Saturday. That's the timeline Ultra Chlor makes possible.
High available chlorine for maximum recovery impact. Calcium hypochlorite delivers a higher effective chlorine concentration than stabilised granular products — which is exactly what you need when you're recovering a problem pool rather than maintaining a good one. When the situation calls for maximum impact, this is the product.
The correct recovery product after any neglect period. A week away, a busy stretch without maintenance, an extended holiday — chlorine levels drop and algae starts. Ultra Chlor resets your chemistry before a manageable situation becomes an expensive one. Keep 5 kg on hand and you always have the recovery option available.
5 kg for multiple shock treatments or a full maintenance season. Whether it's emergency recovery capacity or consistent high-strength maintenance on a large pool — this is the volume that means you're never caught short when you need it most.
When a pool needs serious recovery, you need a product that doesn't negotiate. High-strength, fast-acting, built for the moment when gradual won't do it. ULTRA CHLOR is calcium hypochlorite at the concentration that pool technicians reach for when a pool needs to come back from the edge — and at 5 kg, it's the size that handles the job properly rather than running out halfway through. The pool emergency that becomes a weekend recovery rather than a weekly problem — that outcome is a product decision. This is that decision.
