I start saying that each aquarist has his own idea of what meets the definition or not, however I try to give a representation the more univocal and unifying I can.<\/p>\n<p class=\"western\">Usually organic charge is seen as the ensemble of all waste substances dissolved in water and that should be eliminated, in order to maintain oligotrophy. This firs definition has a negative meaning and often we heard senteces like: reduce fish feeding so you reduce organic charge. Such a concept is not entirely incorrect but surely reductive and extremely misleading, however it provides a first elementary definition: organic charge is represented by all the substances which decomposition causes water pollution.<\/p>\n<p class=\"western\"><img decoding=\"async\" class=\" aligncenter\" src=\"https:\/\/www.joy-reef.com\/wp-content\/uploads\/2015\/07\/15032012293-e1436680833556-189x300.jpg\" alt=\"\" width=\"239\" height=\"379\" \/><\/p>\n<p class=\"western\"><span lang=\"en-US\">Let&#8217;s better analyze the key word \u201corganic\u201d: <\/span><span lang=\"en-US\"><i>what concerns living beings, animals or plants, it contrasts to inorganic.<\/i><\/span><\/p>\n<p class=\"western\">This second definition is sharply well-fitting and let us to include in the definition all the living species we host in our tanks, from algae to fishes, passing through bacteria and microfauna. This is a wider point of view: organic charge consists of all the animals and algae that establish deep interactions between themselves and their habitat, exchanging substances and energy.<\/p>\n<p class=\"western\"><img decoding=\"async\" class=\" aligncenter\" src=\"https:\/\/www.joy-reef.com\/wp-content\/uploads\/2015\/07\/2013-09-15-135104_underwater-coral-reef-fish-bubbles-nature-300x169.jpg\" alt=\"\" width=\"320\" height=\"180\" \/><\/p>\n<p class=\"western\">Now we have made a bit of clarity, I want to recall a concept that should be already known by most: when we talk about increasing or decreasing organic charge, we are talking about varying tank&#8217;s internal dynamics, so we must pay the maximum attention and keep in mind any possible consequence of what we are doing. The simple addition of a new fish inevitably bring a decompensation, we must be able to evaluate if the system will react and adapt itself to the new condition. About this I suggest to read the articles dedicated to homeostasis and oligotrophy which represent the natural consequence of what just expressed above.<\/p>\n<p class=\"western\"><span lang=\"en-US\">Finally I suggest another <\/span><span lang=\"en-US\">food for thought. We said that organic matter contrasts inorganic matter, however this contrast is only of semantic nature: quoting Lavoisier \u201ceverything transforms\u201d, organic matter is decomposed to inorganic and inorganic is in turn fixed to become organic.<\/span><\/p>\n<p class=\"western\"><img decoding=\"async\" class=\" aligncenter\" src=\"https:\/\/www.joy-reef.com\/wp-content\/uploads\/2015\/07\/Marine-trophic-pyramid-300x200.png\" alt=\"\" width=\"354\" height=\"236\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this article we try to give this term a definition, since it is sometimes misused and often causes misunderstandings [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":408,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[],"class_list":["post-1068","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-chemistry"],"_links":{"self":[{"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/posts\/1068","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/comments?post=1068"}],"version-history":[{"count":1,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/posts\/1068\/revisions"}],"predecessor-version":[{"id":85224,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/posts\/1068\/revisions\/85224"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/media\/408"}],"wp:attachment":[{"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/media?parent=1068"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/categories?post=1068"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.joy-reef.com\/en\/wp-json\/wp\/v2\/tags?post=1068"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
