SeachemMatrix and Stability Aquarium Bio Media

Everything arrived as advertised, in good condition and very quickly!!!!

Matrix is a high-porosity biological filter media designed for aquarium filtration. Matrix has a vast internal pore network that provides surface area for the attachment of beneficial bacteria. Porosity and high surface area alone should be the measure of biomedia.Matrix has a primarily macroporous internal pore structure. This means the pores are large enough for the bacteria to enter and form stable colonies. Large surface area measurements sound impressive but if the pores are too small the bacteria cannot get in and colonize the media. This means the bacteria can only grow on the unprotected surface of the biomedia. The colonies are vulnerable to washout caused by high velocity “microshear,” which is the scrubbing effect of water flowing over smooth surfaces.Seachem Matrix protects nitrifying bacteria inside the porous network so the colonies remain undisturbed. But there’s more. Under the right conditions natural denitrification can occur, lowering nitrate levels without the need for a special de-nitrification filter. Matrix provides the right microenvironment that allows nitrification and natural denitrification to take place in the same filter.Seachem Matrix will remove ammonia, nitrite and nitrate! Matrix can be used in any power filter, canister filter, contactor or filter sump. Matrix never needs replacing and can be rinsed if it becomes dirty.

I purchased the 1 gallon sized Matrix due to the cost savings when split with a friend. We each got 2L of Matrix for our canister filters.This filter media works very well. My water is clear. My water tests all show good values, with no signs of ammonia, nitrate or nitrites. All fish are happy and thriving. My planted tank is looking great!I can't say how this will work over years, but for the last 2.5 months, this has been doing its job and the fish are all thriving.Maintenance thus far has been a bi-weekly rinse out of my filter sponges, and for the first time, a quick shake and rinse of the basket full of Matrix. I didn't scrub or do anything to remove more than the loose sludge that was sitting on the media. My sense is the less you do in disturbing the good bacteria, the better. Just need to clean out the gunk to allow for good water flow.I had some extra and added it to my son's 3 gallon tank filter. I can't say it's changed the world, but I would think it's helping in keeping those fish happy too.

Best stuff I ever used. I use this in my fluvel fx6 it’s worth the money

This is, by far, the best filter media you can buy. Tons of little nooks and crannies allow billions of bacteria to colonize and digest all your ammonia and nitrites. Because the bacteria can literally colonize deep inside each piece of Matrix, some anaerobic bacteria are able to gain a foothold. These definitely take a bit longer to establish, about six months. But they digest your nitrates! So depending on your load factor, you can definitely reduce the number of water changes and maybe even practically eliminate the need for water changes to rid your tank of nitrates. There simply is no better, or even comparable, product out there.

This review is meant for both Seachem's Stability and Seachem's Matrix.I helped my son set up his 120 gallon African cichlid tank. We went through about 5 or 6 different filters and settled on an Eheim. From what we had learned from our research on tank setups we had understood that the filter media, once properly colonized, will remove ammonia and nitrites from the water but will not remove nitrates (ammonia gets converted by one kind of bacteria in the filter to nitrites and in turn another kid of bacteria will convert the nitrites into nitrates). The only way to reduce the nitrate levels is by either having live plants or even better, periodic water changes. We were also told that if we have a deep enough substrate then after about 6 months or so, if we get lucky, deep in the substrate will develop a bacterial colony that will help reduce the nitrates.As I continued my research I stumbled on to the Seachem web site. I was impressed by the specs of their Matrix product. It claimed to be able to support bacteria that will eliminate nitrates from the water. Great! Now all I have to do is buy this filter media, wait six months and I'm all set. Not only that, but from what I've read on the Internet, it could take up to two whole months for the ammonia and nitrites eating bacteria to properly develop.Well, luck for me, I found the Stability product. I added both the Matrix filter media and Stability to my setup (Stability needs to be added to the water on a daily basis for one week) and tested the water after one week. I was pleasantly surprised to see that the ammonia and nitrites levels had dropped down to 0! My son was telling me not to bother testing for nitrates because it's guaranteed that they'll be there. I tested anyway and guess what? Zero!This works like magic!

Been down the Biopellet road, the Refugium road too. But know this, Matrix works. The down part is that. It takes a solid 6 weeks to get the bacteria established.... I have a 165-gal tank, and have 2 tall, clear, empty RO style canisters with the Matrix stones, piped 1 into the other. I have standard RO 1/4" tubing with a valve to regulate the flow. Trust me, you can have control over your nitrates with Matrix. It's a lot like pumice-stone. :-}

Meu aquário tem 6 litros. 4L é Matrix.... eeeee brincadeira.Balde com tampa.Granolometria excelente.Pedaços de uma rocha escura tb

Goed product

Köpte detta då det skulle fungera mot Nitrit vilket inte mycket gör. Har 2 filter ett JBL 1900e på mitt 720L akvarium och ett Aquael 2000 på mitt 450L + några filter till på dessa. Efter ca 4 månader hade jag knappt någon nitrit alls inför vattenbytet jag gör var 14 dag. Innan var Nitrit halten strax under 50 nu under 20. Bra produkt som gör det den lovar med ge den lite tid att etablera rätt bakterieflora.

Es el mejor material para la colonias bacterianas de un filtro de acuario.Es el material más poroso, para que las bacterias se puedan instalar.

Senza dubbio è il miglior materiale filtrante che si può trovare sul mercato, di gran lunga migliori dei cannolicchi in ceramica: secondo diversi test fatti al microscopio, risulta che la superficie di queste pietre (che in realtà è pietra pomice trattata e selezionata) è la più porosa di tutti gli altri materiali filtranti... Questo sta a significare che i batteri hanno più spazio per riprodursi.Più batteri ci sono, più equilibrata sarà la qualità dell'acqua dell'acquario e quindi, meno alghe nel lungo periodo. È risaputo che i batteri derivano dai processi di decomposizione delle sostanze tossiche (tra cui ammonio e nitriti), in Nitrati che servono per la crescita delle piante.Io ne ho comprati 4 litri per il mio filtro Oase Biomaster 350: ho tolto tutte le spugne che ci sono nel filtro (inutili) e riempito tutti gli scompartimenti con 4 litri di Seachem Matrix, solo nell'ultimo scompartimento ho inserito la lana di perlon (più che sufficiente per la filtrazione meccanica). Questo è il metodo che utilizza la maggior parte degli aquascapers professionisti: è più importante la filtrazione biologica piuttosto che quella meccanica (che è relativa ai cambi d'acqua, alla pulizia ed alla manutenzione del filtro).Ho più di 10 anni di esperienza nel campo dell'Aquascaping e posso dire con certezza che Seachem Matrix è fondamentale per un acquario di successo.
