This means that plants cannot divert iron from older leaves to new ones. Therefore, deficiency symptoms appear first on new or young leaves. Because plants use iron to produce chlorophyll, a lack of iron results in chlorosis, or yellowing, of the younger leaves. Stems may also appear short and slender. If the deficiency is severe and prolonged, each new leaf emerges lighter in color than the preceding leaf. When choosing an iron supplement, it is important to know the distinction between the two forms of iron. The iron will be in one of two oxidation states: ferrous having a +2 charge, or ferric having a +3 charge. Ferrous iron, the preferred iron form and is soluble in water at any pH. Ferric iron, however, is only soluble below a pH of around 5.5; but if the pH is higher than 5.5, which more than likely it will be in a planted aquarium, the ferric iron will become insoluble and precipitate, settling in the root zone. Once this occurs, foliar absorbtion becomes impossible. To overcome this precipitation, competing products employ a chelate of ferric iron: iron-EDTA. While this does keep it soluble, it has a couple of drawbacks with respect to foliar uptake of iron. (1) Iron-EDTA bonding is very strong, thus very little of the iron will be available to the plants over a given time frame and (2) Physiological energy must be expended by the plant in order to extract the ferric iron from EDTA-iron and then convert (reduce) it to the ferrous form. Our approach is different in that we use a complex (not chelate) of ferrous iron in Flourish Iron™. Flourish Iron™ is a highly concentrated (10,000 mg\/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a bene?t from Flourish Iron™ because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it. Despite what other manufacturers may intimate, gluconate is not harmful to plants or fish. In fact, ferrous gluconate is better suited to foliar feeding than is iron-EDTA owing to the relatively weaker iron-gluconate bonding vs. iron-EDTA bonding. In addition, ferrous gluconate has the added bonus of being a source of carbon.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"16.91 fl oz (500 mL)","offer_id":52073818292545,"sku":"SEA-047302","price":14.46,"currency_code":"USD","in_stock":true},{"title":"67.63 fl oz (2 L)","offer_id":52073818325313,"sku":"SEA-047807","price":49.62,"currency_code":"USD","in_stock":true},{"title":"8.45 fl oz (250 mL)","offer_id":52073818358081,"sku":"SEA-047609","price":9.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/8968\/2497\/files\/media_991d5403-f254-42c9-801e-6245478e9b49.jpg?v=1786428142"},{"product_id":"seachem-clarity","title":"Seachem Clarity","description":"\u003ch1\u003eSeachem Clarity\u003c\/h1\u003e\u003cp\u003eSeachem Clarity Features Water clarifier for marine and freshwater Clears all types of clouding Reef and plant safe Overview Clarity™ is the ultimate clarifier for both fresh and saltwater.

Additionally, polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation\/alkalinity depletion. Reef Calcium™ utilizes a chained organic calcium rather than an ionic calcium. When a coral absorbs a molecule into its tissue, it uses the same amount of energy regardless of molecular size. However, charged molecules require more energy. When an uncharged molecule of Reef Calcium™ is absorbed, the coral acquires multiple calcium atoms as well as an easily metabolized carbohydrate with less energy expended than it uses for ionic calcium uptake. Therefore, at lower calcium levels, corals can still take in as much calcium through our organic chains as they would at much higher levels of ionic calcium. Reef Calcium™ may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement (Reef Complete®, Reef Advantage Calcium™). Reef Calcium™ is intended to maintain calcium levels; if calcium becomes seriously depleted one should either perform a water change or use an ionic calcium supplement to restore the depleted level of calcium.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":52073818980673,"sku":"SEA-035903","price":93.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/8968\/2497\/files\/media_5c707907-2809-4bc9-9599-c6601c35b397.jpg?v=1786428150"},{"product_id":"seachem-flourish-glue","title":"Seachem Flourish Glue","description":"\u003ch1\u003eSeachem Flourish Glue\u003c\/h1\u003e\u003cp\u003eFeatures Cyanoacrylate adhesive Attach moss and plants to rocks, driftwood, and even gravel No more thread, no more weights Bonds within seconds Can be used underwater Overview Flourish Glue™ is a superior cyanoacrylate gel for attaching moss and plants to rocks, driftwood, and even gravel.

The material has a high surface area and supports a high density of bacteria. Although de?nitrate™ has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic. “Live” rocks or reef rocks remove nitrate by anaerobic denitrification. de?nitrate™ removes nitrate by the same process. Efficiency is magnified several folds by forcing the water to filter through the porous de?nitrate™. As with reef rock, anaerobic conditions are achieved by the porosity and the depletion of oxygen by the aerobic process at the surface. Excessive flow rates should, therefore, be avoided, as they may impede development of an adequate anaerobic environment to support denitrifying bacteria. de?nitrate™ is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters. At high flow rates (greater than 100 US gallons per hour), it will function solely as an aerobic filter.

Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Acid Buffer™ lowers pH and buffers between 6.0 and 8.0 when used with Alkaline Buffer™. As Acid Buffer™ lowers pH it converts carbonate alkalinity (KH) into available CO 2 . What is the difference between Acid Buffer™ and Acid Regulator™ A: The difference is that Acid Buffer™ is a straight acid source and Acid Regulator™ is a phosphate based buffering system. Acid Regulator™ has a greater ability to maintain a pH as were a straight acid source can have a slight pH drift. When you are trying to avoid any additional phosphates I would go with the Acid Buffer™ and Alkaline Buffer® products but if that is not an issue, then the Acid Regulator™ will maintain a more constant pH.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"35.27 oz (1 kg)","offer_id":52073821339969,"sku":"SEA-024709","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/8968\/2497\/files\/media_e139ea65-792e-43aa-a307-f682459899d3.jpg?v=1786428199"},{"product_id":"seachem-ammonia-alert","title":"Seachem Ammonia Alert","description":"\u003ch1\u003eSeachem Ammonia Alert\u003c\/h1\u003e\u003cp\u003eFeatures Seachem sensor technology Continuously detects and monitors free ammonia No test kits, chemicals, or procedures are needed; just constant readings Lasts over a year Marine and freshwater Innovative color-coded monitoring device for continuous detection of toxic ammonia. Seachem Ammonia Alert Device alerts you to high levels of free ammonia without need for a test kit. The sensor changes color from yellow to green to blue when ammonia levels increase in your aquarium. Detects less than 0.05 mg\/L free ammonia and alerts you to this #1 killer of tropical aquarium fish. Inconspicuous and attaches directly to inside glass with included suction cup. Lasts for over a year before sensor needs replacement. For fresh or saltwater aquariums. More Information Interpretation As little as 0.02 mg\/L of free ammonia will produce a greenish hue on the detector surface. This corresponds to a total ammonia (both ionized and free ammonia) of 0.25 mg\/L in marine water at pH 8.3. In freshwater at pH 7.0, this corresponds to 3.6 mg\/L total ammonia. Free ammonia is much more toxic than ionized ammonia. As free ammonia, the ALERT color corresponds to about 0.05 mg\/L, ALARM to about 0.2 mg\/L, and TOXIC to about 0.5 mg\/L. The ALERT concentration is tolerated for several days, ALARM for a few days, and TOXIC is rapidly harmful. This product is not recommended for use at acid pH. Care No care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with fingers, since skin oils can damage it. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor. Sensitivity improves with age, provided the unit is not allowed to dry out, however, drying does not permanently impair the unit. For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Red enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit. The response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle: color should develop rapidly. General Information Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg\/L (ppm) free ammonia and alerts you to the #1 killer of tropical aquarium fish before any sign of stress. It lasts over a year. Marine or freshwater use. In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures is required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":52073821405505,"sku":"SEA-001007","price":10.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/8968\/2497\/files\/media_fcc6616a-5601-4a59-b2f8-4ef083621729.jpg?v=1786428202"},{"product_id":"seachem-matrix-carbon","title":"Seachem Matrix Carbon","description":"\u003ch1\u003eSeachem Matrix Carbon\u003c\/h1\u003e\u003cp\u003eSeachem Matrix Carbon Features High efficiency spherical carbon Very little impact on pH due to low ash content Lowest leachable phosphate level on market High removal capacity; large surface area Overview MatrixCarbon™ is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. MatrixCarbon™ has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0. While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon™ has the lowest detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon™ outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use. While carbon is generally considered to be a chemical filter, that is not precisely true. It is in fact a mechanical filter as well, but it is only capable of mechanically filtering objects of molecular size. It functions through extremely small cracks and crevices, called macropores and micropores. Microporous carbons remove primarily metals and smaller ions (like trace minerals) and are best suited to air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration. The ingredients from which a carbon is manufactured determine whether it will be macro- or microporous. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons. MatrixCarbon™ is a bituminous coal-based, macroporous carbon. It is the only spherical carbon on the market, allowing for maximum water flow. It is sized to allow full penetration by water, but not small enough to escape filter bags. All carbons contain phosphate. However, that phosphate DOES NOT come from washing the carbon with phosphoric acid. Most carbons are washed with sulfuric acid. The phosphate is contained in the ash from the carbon source. The main purpose of acid-washing is to remove ash. Because of MatrixCarbon’s™ hydrodynamic properties, more ash is washed from our carbon than any other. Therefore, it has the lowest leachable phosphate on the market.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"16.91 fl oz (500 mL)","offer_id":52073821471041,"sku":"SEA-010306","price":20.43,"currency_code":"USD","in_stock":true},{"title":"3.38 fl oz (100 mL)","offer_id":52073821503809,"sku":"SEA-010504","price":11.17,"currency_code":"USD","in_stock":true},{"title":"33.81 fl oz (1 L)","offer_id":52073821536577,"sku":"SEA-010702","price":35.23,"currency_code":"USD","in_stock":true},{"title":"67.63 fl oz (2 L)","offer_id":52073821569345,"sku":"SEA-010801","price":70.46,"currency_code":"USD","in_stock":true},{"title":"676.28 fl oz (20 L)","offer_id":52073821602113,"sku":"SEA-010108","price":704.62,"currency_code":"USD","in_stock":true},{"title":"8.45 fl oz (250 mL)","offer_id":52073821634881,"sku":"SEA-010603","price":12.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/8968\/2497\/files\/media_0185fcf3-05d7-4420-a41d-522e5d211931.jpg?v=1786428205"},{"product_id":"seachem-algae-scraper-replacement-scrubber","title":"Seachem Algae Scraper Replacement Scrubber","description":"\u003ch1\u003eSeachem Algae Scraper Replacement Scrubber\u003c\/h1\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":52073821700417,"sku":"SEA-032148","price":5.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/8968\/2497\/files\/media_5f792737-f7e6-496f-af91-17c9c86bec7e.jpg?v=1786428207"},{"product_id":"seachem-multitest-phosphate","title":"Seachem MultiTest: Phosphate","description":"\u003ch1\u003eSeachem MultiTest: Phosphate\u003c\/h1\u003e\u003cp\u003eFeatures Measures inorganic phosphate to less than 0.05 mg\/L Multi-cavity plate for simultaneous testing of up to 6 tests at the same time Includes reference for test validation Marine or freshwater Phosphate in natural sea water ranges from less than 0.01 mg\/L to 0.3 mg\/L.
