(4) Activated carbon: Activated carbon is a porous carbonaceous material, charcoal, activated carbon and charcoal belong. Activated carbon for trace elements in the water, pigments, and other substances with a high degree of odor removal capability. So activated carbon removes chlorine in the water (to As for tap water), activated carbon, organic polymer material has a strong adhesive force, so the use of activated carbon for some time, the ability to remove trace impurities in the water will decline, we activated carbon exposure in reduction under the sun, and so prolong the effectiveness of activated carbon. Note: During drugging aquarium filter should first be removed from the activated carbon, the end of the aquarium drugged, then back into activated carbon, activated carbon to remove the remnants of the drug, so as soon as water purification.
(9) maifanite: can absorb toxic substances in water, amtrol water purification, natural release of various trace elements and oxygen, in order to improve breeding density. Adjusting the pH value of the water quality introduced amtrol in the filtering medium is used to indicate the strength of the acid or alkali solution, pH value 0-14 indicates, pH 7 neutral amtrol point, pH value below 7 is acidic, pH is greater than 7:00 alkaline and mainly represents the concentration of the water hardness of calcium and magnesium in water, to the water content of calcium carbonate (mg / l) is expressed, calcium, magnesium, carbonate and bicarbonate in the water, most of the dissolved limestone land come. Different aquarium from different original habitat, water pH (pH) and hardness have different requirements, in order to be able to successfully grow and aquarium breeding, amtrol the filter should retain a space, can be placed on a special stone or clay, when The flow through the filter, you can adjust the water pH and hardness. Add peat soils (also known as soil, humus) in the PH value of the adjustable filter rainfall, so the water tank becomes acid.
