Pools can often be contaminated with matter that cannot be removed using sanitisers or oxidisers and which can affect the enjoyment of the swimming pool. Such conditions exist when there are fine particles in the water that the filter is unable to remove, phosphates that algae can feed on, and other unwanted chemicals and matter that prevent sanitisers and oxidisers from working effectively. A number of chemicals are available that can deal with these situations.

Boric acid is a very useful water enhancing additive as it carries out 3 important actions: removes carbon dioxide from the water that algae feed on, helps to stabilise pH and increases the efficiency of other chemicals. It also gives the water a nice silky feel and prevents tangling of long hair. Bioguard Optimiser is 100% boric acid, and it is also a component of Bioguard Power Chlor and Pacific Blue Power Tabs.
