Seachem Matrix Bio Media 250ml

I love this product! It really works to eliminate ammonia, nitrates and nitrites! I have seen a remarkable improvement in my tanks water quality since implementing this product into my HOB filter!

just pumice stone.

This is just pumice stone get a bag from a rock quarry or hardware store and youll be just as good for less.

Does what its suppose too no complaints here.

Best filter media by far. Get a media bag!

Make sure you get a mesh bag for these. Im not sure why it doesnt come with one. I had it clog the water intake for the propeller motor on my canister filter. Some of the rocks are like pebbles and will float around and may cause you issues. I took it out and Im probably not gonna use it. Its not really nessecary.

Muy bueno
