Low calcium hardness is one of those pool problems you don't see coming until it's already eaten into the surface.

Baracuda's Calcium Hardness Increaser lifts a soft pool back into balance, which matters most for concrete, pebblecrete and fibreglass pools that can pit or etch when the water's too soft. It also looks after your metal fittings and heater, since corrosion speeds up when hardness drops too low. Dissolve it in a bucket of water first rather than tipping it straight in, add it with the pump running, and retest after a day before deciding whether you need more.

This comes in a 4kg tub, enough for a straightforward top-up on a home pool. Full specs are in the tabs below, and if you're not sure what your test strip is telling you, bring the reading in to 34-52 Milnes Rd, Strathalbyn or call us on (08) 8536 4333.
