Seachem Laboratories Matrix Carbon, 500ml

well all seachem products have intact sealing after opening the lead of any container. But this time there was no sealing. I doubt if the supplier has mixed any other active carbon with the real product. Important a bit upset. But if it really does not contain sealing then it ok. Only seachem active carbon producers will know.

very good.prompt delivery and the product is really good.

Best on the market

This stuff is amazing. I have a 20 gallon mixed reef tank and have been fighting water clarity since I started it. Some random thread mentioned using this to help, so I ordered some and some media bags and off I went.The day I put it in, the water was fairly cloudy, maybe 25% opaque. I put around 1/4 cup into a media bag, zip tied it shut, and tossed it into the middle chamber of the AIO back area.I noticed visible water clearing in a few hours, and by the next morning the water was crystal clear, to my complete shock and amazement. I did have to replace this after a few weeks, but given the benefit and lowish overall cost, it's a price I'm willing to pay.I highly recommend this stuff if you're fighting water clarity issues.

Brought to polish the water in my marine aquarium and it’s working . Running in a reactor within a bag and it’s working well.

un ottimo prodotto, una resa fantastica su tutti i valori in vasca, vale la pena acquistare un prodotto come questo se si cerca di avere un buon equilibrio per il mese, mese e mezzo, senza dover far altro all'interno del filtro, uso solamente questi prodotti e di questa casa, costano ovviamente ma a differenza di altri durano oltre il mese e mezzo!! così da ridurre gli interventi sul filtro.

Gut, wie alles von dieser Firma.
