Usage: Rinse with clean water and put it into use Dosage: The bigger the fish tank  the more filter material neededEffect The role of volcanic rocks 1: living water. Volcanic rocks can activate ions in water (mainly increasing the content of oxygen ions). The role of volcanic rocks 2: stabilizing water quality. PH stability  it can properly adjust too acidic or too alkaline water to automatically adjust to near neutral. However  the stability of pH value of water quality is very important when Luo Han starts and adds color. The role of volcanic rocks 3: lure color. Volcanic rocks are bright and natural. They have significant attraction to Lohan  red horses  parrots  red dragons  three lake cichlid and many other ornamental fishes. The role of volcanic rocks 4: adsorption. The volcanic rocks are porous and have a large surface area. They can adsorb harmful bacteria in water and the heavy metal ions that affect the organism  such as chromium and arsenic  and even some of the residual chlorine in water. The role of the volcano 5: playing the props. Most of the fish  especially the Rohan  are not mostly mixed  they will be lonely  and Rohan has the habit of playing with stones to build their homes  so the light weight of the volcano has become a good prop of its play. The role of the volcano 6: to promote metabolism. Trace elements released from volcanic rocks can promote the metabolism of animal cells  and bring out harmful halogens in the body and clean up dirty things in cells. The role of the volcano 7: the culture of nitrifying bacteria. The high surface area produced by the porosity of volcanic rocks is a good hotbed for nitrifying bacteria in culture water. The role of volcanic rocks 8: matrix material for the growth of water and grass\u003cbr\u003e\u003cli\u003eNatural volcanic rock  Red  0.88 IB \u003c\/li\u003e\u003cli\u003e Filter Media:Ornamental fish essential filter \u003c\/li\u003e\u003cli\u003e The surface is covered with pores  The more pores  the better the water purification \u003c\/li\u003e\u003cli\u003e Breathable water permeability is good  help to cultivate and produce \u003c\/li\u003e\u003cli\u003e 400 g \/ bag The size of the stone is different\u003c\/li\u003e","brand":"BCQLI","offers":[{"title":"Default Title","offer_id":51902467015022,"sku":"WBPETB07D3SFJHH","price":15.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/9575\/5374\/files\/81Abyo7R0aL.jpg?v=1741686958","url":"https:\/\/petocartv.com\/products\/bcqli-400g-sphere-bio-filter-media-for-marine-and-freshwater-aquariums-red-volcanic-rock","provider":"Petocart","version":"1.0","type":"link"}
