Aquaz Posted February 21, 2005 Share Posted February 21, 2005 Surface waters of tropical oceans contain very low amounts of nutrients such as phosphate, typical phosphate values can be 0.003ppm or less. While every progressive marine hobbyist strives for better skills and struggle to meet the hobby’s demands, the one of the biggest problem is the fight against Phosphate (PO4). Phosphate, in excess can drive nuisance algae growth, and inhibit calcification of corals and coralline algae. Phosphate is input to the aquarium through feeding fish food and tapwater topups; both sources may be laden with orthophosphate. A Phosphate (PO4) testkit is essential for determining and track the levels in the aquarium water. There are natural methods of phosphate removal such as the use of macroalgae growth to compete against the nuisance algae for phosphate; however that option might not be available to all. Skimming will remove organic orthophosphate before breaking down into inorganic orthophosphate. Use of limewater as a clarifying solution can precipitate phosphate and other contaminants from freshwater tapwater topup. Aquaz recommends the use of Kalkwasser Premium for calcium hydroxide with unparalleled solubility and the lowest heavy-metal content. Maintaining a high pH of at approximately 8.4 may also help keep phosphate binded to rock and sand and from re-entering the water column. Aquaz has included a phosphate binding agent in its product range made from granular ferric oxide (GFO). An iron based media originally developed for arsenic removal but was found to work very well in removing phosphate with a higher absorption rate than aluminium base media. According to studies, iron media, in general, binds a wide range of compounds including arsenic, selenium, silicate, organics, trace metals- manganese, cobalt, nickel and zinc. In view that these kinds of filter media need to be changed when exhausted, Aquaz believe in launching our phosphate media, which is reasonably economical for everyone to use on a regular basis. Carbphos Premium™ Retail Price SGD$24.00 Purephos Premium™ Retail Price SGD$28.00 Hints & Tips: *To obtain the best results from the filter media and to keep your tank at very low or zero phosphate levels it is important when starting up a new tank or a mature tank with phosphate levels, to use the filter media on a permanent basis. The filter media will absorb phosphate, silicates and arsenic. It is entirely safe in both fresh and saltwater systems. *Change Media when phosphate levels begin to rise after three to six months, depending on original levels. With high levels of phosphate the media can be saturated much faster for the initial usage. The iron media in Purephos Premium™ and Carbphos Premium™ is an absorbent and will bind phosphate to the surface of the granule, once full it will not release phosphate back into the aquarium but needs to be replaced with new media. *Before use, rinse the media in running water/old saltwater or RO/DI water before placing it in the tank. Rinsing the product will not affect its preformance. *It is not a must to run a specific media reactor, although highly recommended. With a dedicated reactor you can control the flowrate to achieve optimal results. *The media can be put in a nylon/polyester filter bag and placed in a high flow area. In marine aquariums where we run our parameters usually at saturation levels (e.g high calcium and alkalinity) - caking of the media (by calcium precipitation or bacteria) usually occurs when it is used for a long period. This prevents tank water from an optimal flow through the media. To overcome this you can rinse the media bag in old saltwater and loosen the granules, or if this happens in a reactor - run the flow in the opposite direction for a short period. *Do not sprinkle directly into the aquarium. *Adsorption is a continuous process conducted at a specific flow rate or velocity. In addition to velocity, the other key process parameter is media contact time, which dictates the amount of water residence within the media bed required for optimal adsorption. The water flowing through the media should be clean(prefiltered) and gentle enough to not fluidised the media. Fluidization of the media will cause the grains to rub against each other with the fine particles escaping into the tank. *A higher efficiency of absorption is achieved if the water slowly flows through the granules ensuring maximum contact with the water. *It is not possible to overdose Purephos Premium™, an increased amount of media will only increase the absorption lifespan capabilities.

SRC Member junyong84 Posted February 22, 2005 SRC Member Share Posted February 22, 2005 what are the main diff btw these 2 products? purephos is juz pure phos absorbing media? and carbophos is a mixture of activated carbon and phos abosrbing media?
