Fi-Clor Spa Hardness increaser should be used to raise the calcium
hardness level in spa water. calcium hardness is the amount of
dissolved calcium and magnesium in pool water. If there is insufficient
dissolved calcium, it will be difficult to balance the water – there
could also be grout loss in tiled spas. High levels are not a major
cause for concern provided the pH and alkalinity are within recommended
parameters, but the reading should be kept below 750g/l (ppm) if
- Take a calcium hardness reading using
your test kit or strips. You will need to correct the calcium hardness
if the reading is below 175mg/l (ppm) in acrylic spas or 250mg/l (ppm)
in tiled spas.
- The dose rate is 10g of Fi-Clor Spa Hardness Increaser per
1,000 litres (220 galls) of spa water. each dose will raise the hardness
by approx 10mg/l (ppm). Add no more than 100g at any one time,
otherwise the water may cloud exxessively.
- With the circulation system running sprinkle the product
directly into the water around the perimeter of the spa. Do Not pre
dissolve as this could generate exxessive heat. Only use when bathing
has ceased and avoid the area around the skimmers. Bathing may
recommence when all the material has fully disolved.
