ACO® is an Active Catalytic Oxidiser that works by harnessing the natural energy of UV light from the sun to catalyse the formation of free radicals to increase the RedOx potential in the water. Free radicals are the active ingredients of ozone. They oxidise just like chlorine to remove pollutants
but do not form noxious disinfection by-products. ACO® is not consumed in the process, it just makes what happens naturally much more efficient. In chlorinated systems ACO® also protects chlorine from photolysis by sunlight and makes it last three times longer in outdoor facilities. ACO®
does the same as cyanuric acid, but instead of reducing oxidation capacity, ACO® increases the oxidation potential of the water.
APF® is a multi-spectrum coagulant and flocculant that removes pollutants from solution and flocculates fine suspended solids, such as skin cells and bacteria, into large particles that are easily removed by AFM® (Activated Filter Media).
No single flocculant or coagulant can remove everything from the water. APF® is a precise combination of 6 different electrolytes and polyelectrolytes to cover the widest possible range.
Dissolved constituents of water make up 80 % of the oxidation demand and suspended solids around 20%. Everything that is filtered out does not need to be oxidised.
When the correct flocculation is used in combination with AFM®, oxidation demand is reduced and RedOx potential increases. In chlorinated systems unwanted disinfection by-products are reduced by up to 80 %.
Unicellular algae and bacteria need phosphates to transport nutrients across their cell membranes. In the absence of phosphates they cannot metabolise any nutrients that are present in the water.
NoPhos removes phosphates that enter the system from make-up water supply, from animal feed and from wind blown debris. Phosphates are fertilisers and if controlled, algal and bacterial growth can be managed. If phosphates are removed they will starve and algae/bacteria are eliminated over a period of about six weeks.
NoPhos is a natural product that can be safely used in living systems. It is widely used in aquaria and mammal systems around the world including use for management of phosphates in living coral culture. Dryden Aqua’s knowledge as marine biologists ensures the purity and consistency of chemical content that determines its suitability for aquarium use.
NoPhos uses Lanthanum, a charged ion which reacts with phosphate to form an insoluble precipitate that is removed by AFM®, or it forms an inert deposit on the bottom of the pool that is easily remove.
