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 250 ml bottle.
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.

Tank is lightly stocked and planted and I was even doing large water changes (50% weekly) to keep nitrates in control. Have a Siamese algae eater but he alone was struggling to keep the tank and decor free of algae. nothing I tried seemed to make a difference (using API test kit to measure nitrates and phosphates).
Got recommended Matrix and I was initially very sceptical.
Popped the recommended dose for a 125ltr tank into my external filter (JBL e901 cristalprofi).
No difference in nitrates and still reading 40ppm. Decent range for a planted tank should be within the 5ppm range.
Tested it again after a water change thinking I knew what to expect; nitrates would still be sky high. Thought I was misreading the test kit when it was reading 5ppm of nitrates (light yellow).
Tap water is high in nitrates and phosphates at source. However, the use of Matrix and large water changes has noticeably reduced the green dust and spot algae. Plant leaves are free of algae and look much more colourful and vibrant.
Funziona perfettamente, è facilmente pulibile una volta ogni tanto sotto acqua corrente del rubinetto (in 15 secondi è tornato come nuovo).
Io lo uso in una retina con cerniera acquistata su Amazon, in modo che sia rapido da mettere e togliere dall'aquario in corso di pulizia (semplicemente prendo il sacchetto e lo sciacquo sotto l'acqua corrente e il Matrix che è all'interno si pulisce).
Ha una porosità molto elevata permettendo ai batteri utili per il ciclo dell'azoto di insediarsi e convertire la dannosa ammoniaca in nitriti e poi in nitrati (che verranno rimossi grazie ai cambi d'acqua).
Ottimo sia per acqua dolce che salata, sia per acquari di acqua temperata sia di acqua fredda.
Thanks to Amazon .
