Our company is 100% Australian owned and our first swimming pool products were developed in the 1970's. Today our products are available through more than 500 retail outlets Australia-wide and exported to several countries overseas. All of our unique products are "made stronger to last longer" and as such, our premium all seasons algicide products POOL BLOCKS and POOL DROPS Plus outperform all other algicide products which either do not work or simply fail to provide an effective treatment period to get results. Our aim has always been to generate regular repeat custom and a strong word of mouth following by developing products which outperform all others and can be used all year round as a first step in simple pool and spa care. There is no mystery to looking after pool and spa water. Basically, control bacteria with a small amount of sanitiser, eliminate all algae growth and spores with our highly effective, long-term algicide products and keep the pH in the correct range. This simple approach provides superior results with a minimum of maintenance time and chemical costs.
