Siliphos

Dupla Siliphos is a fine-grained compound that has been successfully employed by industry and water suppliers, in fresh water and sewage treatment plants for several years. Its highly active chemical capacity for absorbing phosphates in large quantities makes it an ideal filter medium for aquaria. In aquaria phosphates develop from decayed organic matter and also as a result of excessive feeding, plant fertiliser or decorative material containing phosphates. Phosphates may also enter our aquarium by the addition of fresh tap water containing phosphates. Phosphates are an essential element of living organisms, but harmful in elevated concentrations. In sea water aquaria high phosphate levels inhibit the formation of lime by hard corals and calcareous algae. Due to the increased nutrient levels the zooxanthellae of zooxanthellate corals can proliferate to a degree that they cover the natural colour pigments of the corals. The corals turn brown. A further indication for high phosphate and silicate (silicic acid) levels is the growth of red or brown algae that often form a smeary coat on the aquarium decorations and threaten the life of various organisms. A PO4 level of more than 0.1 mg/l may not be tolerated in a modern coral reef aquarium. Dupla Siliphos is also used to bind undesirable silicates in sea water aquaria. In fresh water aquaria the maximum content should be around 0.3 mg/l. Elevated phosphate levels are often responsible for algae epidemics, poor plant growth and ailing fish.

The constant use of the highly effective filter material Dupla Siliphos ensures that phosphate and silicate levels are kept as low as possible, optimising the chemical balance of water in aquariums. Even when the material is exhausted, no contaminations are returned to the water.

Application: With the included net bag, Dupla Siliphos can be used in any type of filter. 1,000 g will bind 50 g PO4/ 10 g Silicate.
Important: Dupla Siliphos should not be rinsed before use. A possible red “bleeding” is absolutely harmless even to sensitive plants, fish and corals and will disappear in a short time. Dupla Siliphos must not dry out and should always be stored moistened with distilled water. To assure maximum efficiency, a fine mechanical filter (e.g. filter cotton) should be installed upstream. Avoid contact with clothing and other textiles, as stains are hard to remove.
