El mejor material filtrante para acuarios, el artículo vino en la fecha estipulada.

Truly AMAZING! My tank was cloudy for about two weeks. I was losing my mind with alternate solutions. I was told to try Matrix in my Fluval 306 canister filter. Overnight, my tank was crystal clear. I could not believe my eyes. Thank you Seachem, what an amazing product.

I love this whole line of products for my tank maintenance. Check them all out.

This supposed to be one of the best. Just be careful you dont get a return that was swapped out with fake heavy rocks! As long the rock are porous and light they as good.

Seachem...a trusted brand. After having a outdoor koi pond (with bio filtration) in California for many years, we had to move to indoor tanks in New England. However, I never really put much thought into the filter systems that come with todays starter tanks. After having a tank in my daughters room for years (one in which we periodically monitored water properties) we started to struggle to keep some of the fish alive. I decided to take a closer look at our water chemical levels and found we began to struggle with ammonia and nitrates again. It was then that really decided to shift away from the basic carbon filters that come for our specific filter - in which we always seem to throw away established bio filter. I decided that I would try filter padding with Purigen and Matrix - creating a bio filter that I wouldnt toss away each time I replaced the padding. The matrix stones are pumice based, giving them extreme surface area coverage where the bio filter bacteria can become established. I borrowed one of my wifes old nylons to create a flexible bag of matrix stones that was easy to add to the new filter set-up. My only complaint is the powdered dust that is all over the stones when you first open them. Even after a thorough rinsing, the tank became mildly cloudy when the stones were introduced. Within 12 hours that cloudiness was gone. And since using the Purigen/Matrix combo the two tanks have never been more stable and more clear!

Excellent product, just swapped it for the stock ceramic tubes

Best filtration media you can use IMO (and the research seems to back this statement up). Particularly if you have a canister filter (because of the anaerobic possibilities), although it works fine with a HOB filter so long as it has space to fit enough of this rather large media.
