Seachem Matrix Carbon 500mL. Tongs, Tweezers & Scissors. AQUARIUM SUPPLIES. Gravel Vacuums. Ammonia Removal. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons.
Matrix carbon is like no other carbon you've used. It shape is small little balls that pack together very tight without interfering with the flow of water through it. It helps with filtering out the impurities in your water while polishing it at the same time. It can also be used with products such as Purigen to clean your water and give it a crystal clear shine.
I've been using in my Cascade 700 for about 2 years, in my turtle aquarium with 35 gallons of water, for my So. Painted Turtle. With this particular activated carbon, I can go a full 2 months before replacing. I account for 40 gallons of water for measuring the amount of Matrix Carbon or 1/2 a cup. My Aquarium water is always crystal clear w 1/2 water changes and artificial plants, every 2 weeks. I feed my 3+" Painted, 2-1/2 yr old, in a separate clear plastic container. I had read that the Seachem Matrix Carbon had the highest rating amongst a couple qualified professional keepers. I did go three months w/o changing, but feel more comfortable doing every 2 months.
Does the job but the tiny carbon balls are too small to be used with my underwater bubbler corner box filters. The carbon produces a lot of dust in a filter bag.
