<h2>Deep Blue Professional* - Activated Carbon In Jar With Media Bag</h2><p>Activated carbon filter media aggressively adsorbs organic pollutants from medicines and metabolic wastes, detoxifies harmful gases and removes unwanted colors or odors from your water&#046; Coal based activated carbon is more porous and affects your pH less than coconut based carbon&#046; </p><p>We recommend medicating sick fishes in a separate quarantine tank, but if you have to use your main tank, remove carbon first and replace afterwards to remove remaining medicines&#046; Carbon removes trace elements needed for plant and invertebrate growth, so make limited use of it in planted and reef aquariums, and always monitor your water conditions&#046;</p><ul><li>15OZ</li></ul>
