Furthermore, there will be an increase in nitrogenous and phosphorus compounds, encouraging growth of nuisance bacteria and eventually of nuisance algae. The accumulating organics also has a significant effect on light penetration, especially in the blue and near UV spectrum that stimulates coral growth.\u003cspan\u003eStripping out the organics from the water is therefore crucial for the success of the aquarium. Using strong protein skimming, fine mechanical filtration and healthy biological filtration (nitrification and de-nitrification) will treat the large organic particles and the end products of the organic decomposition processes. However, there are many small organic particles that can only be treated by very fine mechanical micro-filtration using activated carbon.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eHow does activated carbon filter water?\u003cbr\u003e\u003cbr\u003eScientifically speaking, carbon removes the organics from water by a physical process called adsorption. Within a reef aquarium, the submicroscopic pores of activated carbon is the final stage of the mechanical filtration process, adsorbing the organic molecules that are too small to be removed by even the finest mechanical filters or physically removed from the water by protein skimming. Adsorption can be thought of as the adhesion of a molecule to surface by attractive forces. This occurs within the submicroscopic pores of the carbon because the attractive forces between the organic molecules and the internal surfaces of the carbon are far greater than the attractive forces that keep them dissolved in solution. This will continue until all of the surface area inside the carbon is used up and it becomes saturated with organics. \u003cbr\u003e\u003cbr\u003eWhat is activated carbon?\u003cbr\u003e\u003cbr\u003eActivated carbon is an extremely porous material with a sponge like structure but with a very large internal surface area relative to its physical size. It is produced from many organic materials that have a high carbon content such as coconuts shells, nutshells, lignite, bituminous coal or anthracite. The carbon-based material is “activated” through physical modification and thermal decomposition in a furnace, under a controlled atmosphere and temperature. The activation process significantly increases the surface area per unit volume of a fine network of submicroscopic pores which is what gives activated carbon its ability to act as a filter material. The specific source of the carbon and the specific activation process determines the physical characteristics of the finished product. There are many different grades of activated carbon and therefore they must be selected specifically for each and every application.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eWhat makes a specific carbon ideal for reef aquariums usage?\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003eThere are a number of internationally accepted tests for evaluating and comparing activated carbon. However, the most significant parameters for selecting a carbon for reef aquariums are the Iodine Number and Methylene Blue Number. These two parameters measure the ability of the carbon to adsorb all of the organic waste from a reef aquarium that is not removed by the mechanical filtration and protein skimming. The higher the number the more organics will be removed from the aquarium per gram of active carbon used. Both of these numbers are about as important as each other and should always be considered together when evaluating test data.\u003c\/span\u003eSome manufacturers quote a Molasses Number, however the molecules in the molasses size range are typically removed by protein skimming and therefore this number is irrelevant when evaluating the suitability of activate carbon for reef aquariums.In the past, carbons have been known to leach phosphate into the water, which is undesirable for a reef aquarium and therefore the lowest levels of Leachable Phosphate are considered better. In reality, as long as the leachable phosphate is below a basic threshold level, any differences below that level is not measurable in reef aquariums and is therefore irrelevant.The cleanliness or dustiness of the product is also a consideration and is measured as the Ash Level. The lower the better as higher levels indicate a larger quantity of particles will be released to the water and a lower actual mass of carbon left to do the filtration. Ash levels are often quoted by manufacturers however it is easiest visualized by viewing the turbidity on adding the carbon to water.In addition to these important indicators, the overall efficiency of the activated carbon will be effected by its physical parameters such as Product Density, TSA, Pore Volume and Mesh Size.Activated carbon produced from lignite and anthracite are not recommended for reef aquariums due to an excessive amount of fine powder released to the water (which may lead to lateral line necrosis “HLLE disease” in some fish).

Furthermore, there will be an increase in nitrogenous and phosphorus compounds, encouraging growth of nuisance bacteria and eventually of nuisance algae. The accumulating organics also has a significant effect on light penetration, especially in the blue and near UV spectrum that stimulates coral growth.\u003cspan\u003eStripping out the organics from the water is therefore crucial for the success of the aquarium. Using strong protein skimming, fine mechanical filtration and healthy biological filtration (nitrification and de-nitrification) will treat the large organic particles and the end products of the organic decomposition processes. However, there are many small organic particles that can only be treated by very fine mechanical micro-filtration using activated carbon.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eHow does activated carbon filter water?\u003cbr\u003e\u003cbr\u003eScientifically speaking, carbon removes the organics from water by a physical process called adsorption. Within a reef aquarium, the submicroscopic pores of activated carbon is the final stage of the mechanical filtration process, adsorbing the organic molecules that are too small to be removed by even the finest mechanical filters or physically removed from the water by protein skimming. Adsorption can be thought of as the adhesion of a molecule to surface by attractive forces. This occurs within the submicroscopic pores of the carbon because the attractive forces between the organic molecules and the internal surfaces of the carbon are far greater than the attractive forces that keep them dissolved in solution. This will continue until all of the surface area inside the carbon is used up and it becomes saturated with organics. \u003cbr\u003e\u003cbr\u003eWhat is activated carbon?\u003cbr\u003e\u003cbr\u003eActivated carbon is an extremely porous material with a sponge like structure but with a very large internal surface area relative to its physical size. It is produced from many organic materials that have a high carbon content such as coconuts shells, nutshells, lignite, bituminous coal or anthracite. The carbon-based material is “activated” through physical modification and thermal decomposition in a furnace, under a controlled atmosphere and temperature. The activation process significantly increases the surface area per unit volume of a fine network of submicroscopic pores which is what gives activated carbon its ability to act as a filter material. The specific source of the carbon and the specific activation process determines the physical characteristics of the finished product. There are many different grades of activated carbon and therefore they must be selected specifically for each and every application.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eWhat makes a specific carbon ideal for reef aquariums usage?\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003eThere are a number of internationally accepted tests for evaluating and comparing activated carbon. However, the most significant parameters for selecting a carbon for reef aquariums are the Iodine Number and Methylene Blue Number. These two parameters measure the ability of the carbon to adsorb all of the organic waste from a reef aquarium that is not removed by the mechanical filtration and protein skimming. The higher the number the more organics will be removed from the aquarium per gram of active carbon used. Both of these numbers are about as important as each other and should always be considered together when evaluating test data.\u003c\/span\u003eSome manufacturers quote a Molasses Number, however the molecules in the molasses size range are typically removed by protein skimming and therefore this number is irrelevant when evaluating the suitability of activate carbon for reef aquariums.In the past, carbons have been known to leach phosphate into the water, which is undesirable for a reef aquarium and therefore the lowest levels of Leachable Phosphate are considered better. In reality, as long as the leachable phosphate is below a basic threshold level, any differences below that level is not measurable in reef aquariums and is therefore irrelevant.The cleanliness or dustiness of the product is also a consideration and is measured as the Ash Level. The lower the better as higher levels indicate a larger quantity of particles will be released to the water and a lower actual mass of carbon left to do the filtration. Ash levels are often quoted by manufacturers however it is easiest visualized by viewing the turbidity on adding the carbon to water.In addition to these important indicators, the overall efficiency of the activated carbon will be effected by its physical parameters such as Product Density, TSA, Pore Volume and Mesh Size.Activated carbon produced from lignite and anthracite are not recommended for reef aquariums due to an excessive amount of fine powder released to the water (which may lead to lateral line necrosis “HLLE disease” in some fish).

Each of the natural pink, red, green\/yellow and blue\/purple pigments are connected with\n\u003cbr\u003especific elements that correlate with the elemental grouping of the Coral Colors A, B, C \u0026amp; D.\n\u003cbr\u003eOur Coral Colors supplements have been formulated such that the ratio of the elements in each supplement are the same as are found in the\n\u003cbr\u003ecombined coral skeleton and soft tissue.\u003c\/p\u003e","brand":"Red Sea","offers":[{"title":"Default Title","offer_id":40199952629895,"sku":"4871","price":26.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/products\/red-sea-coral-colours-abcd-pack-4-100ml-916254.jpg?v=1731257081"},{"product_id":"red-sea-coraline-gro-500ml","title":"Red Sea Coraline Gro 500ml","description":"\u003cp\u003eCoralline algae will grow naturally, without any special supplements in all reef systems optimised for hard corals.
