Seachem Matrix Bio Media 250ml

Love it nice groves for beneficial bacteria to grow, Nice size fits well in canister , but you might wanna get the next size bottle up not much comes in the small.

Use this media in all of my hob, canister, all in one/built in filters. Also used it in place of/in addition to live rock in frag tanks.

Not as much as I invisioned. Barely made a single layer in my external aquarium filter bucket.

so far so good, just installed in my nano bio cube

It should take a while to know how well it works

This product isnt very consistent. Honestly you would fair better by placing lava rock in your filter. I ended getting stones that had very little porous surface. Also media took forever to cycle. I think the claims by manufacturer are a bit off. Id place this just below bio balls in terms of effective bio media. I think even a sponge would be better.

My water never had that polished look until I starting using Seachem Purigen product. I am now changing my media slowly over to their Bio Media. If it works as great as the Purigen I am sure I will be very pleased with the results.

Nice sizes, light weight, very porous. My go to bio filtration media.

Mine has been doing a great job

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