Marineland Black Diamond Premium Activated Carbon – 10 oz.
Marineland Black Diamond Premium Activated Carbon is a high-quality activated carbon designed to help keep aquarium water clean, clear, and free of unwanted organic compounds. It works by absorbing dissolved impurities that can discolor water, create unwanted odors, and reduce overall water clarity.
Black Diamond is an excellent choice for both freshwater and saltwater aquariums, including reef systems. It can be used in a filter media chamber, media bag, or reactor as part of your regular filtration routine.

How to Use
Rinse the carbon thoroughly with aquarium or purified water before placing it into a media bag or filter chamber. Position it in an area with good water flow so water can pass through the media.
Replace the carbon regularly as it becomes exhausted. The replacement schedule will depend on aquarium size, bioload, and the amount of organic material in the system.
For reef aquariums, activated carbon can be particularly useful for maintaining clear water and removing dissolved compounds that can build up over time.
Tip: Always rinse activated carbon before use to remove dust and fine particles. Avoid adding large amounts at once to an established aquarium; use an appropriate amount for your system and filtration setup.

Collapsible content
LIGHT
LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.
MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height.
HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.
FLOW
LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.
MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.
HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.
SKILL
ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.
While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
