Product description

Product Description

Seachem Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10 mm in diameter. Each litre of Matrix provides as much surface as 170 litres of plastic balls. Plastic bio-materials provide only external surface area, whereas Matrix provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. Matrix is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix may be rinsed when needed without damaging the filter. Matrix is compatible with all types of wet or wet-dry filters. Available in 500 ml bottle.

Set Contains:

water treatment

Important information

Directions:

Use 250 mL of Matrix for each 200 L (50 US gallons) of water. Matrix may be placed in any kind of filter and is particularly effective in a canister filter. Matrix is sufficiently large that no filter bag should be required for most applications. Matrix works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications. Use with Stability to more rapidly establish the bio-filter. This dosage may differ from your packaging. Based on updated studies, we've found Matrix treats even more water than previously asserted.

Purchased like 5 times. Very good biomedia for your tank. Cheap too. Very much recommended

I put these in a top, sump kind of filter (it draws water from below into a horizontal platform where the water goes through filter wool, then these rocks, and back into the tank). The rocks allow for beneficial bacterial live and thrive in them. My levels of nitrites and nitrates were controlled to near 0 levels, but the addition of these rocks and continuing to add minor amounts of beneficial bacterial (1-2mL) at each water change. (I also age the water for about a week, use water conditioner, use tropical fish salts, and flourish plant feeder for my plants).

Best sump biomedia money can buy. Introduced this into my sump when I was getting balance issues with blue green slime algea. Basically the sump media couldn't keep up with bioload. Changed some of my outdated media to seachem matrix and now all running beautifully.
