Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs

The media could not be loaded. Yes, probably best to wash it... but honestly not the end of the world if you don't (unless you try adding it to an existing tank with no backup tank to put existing fish from that tank).It will take a couple of days for the dust to settle if you don't rinse it. And if you stir it up again by moving things or planting, it will take a couple more. However, over time, the dust settles down beneath the rocks and is harder to disrupt.I didn't wash mine on a new tank setup and it was barely cloudy for a few days. No fish went in right away so no problem. I think the dust is probably good for the plants since the smaller particles are easier to absorb than whole rocks.I got a second bag of the dark reddish flourite and put that into an existing tank and it got very cloudy, like a storm on Mars or something. Even that cleared up within about 36 hours. (I did have to relocate my fishes to other tanks though because I don't want them choking on the dust)I used the flourite as well as fertilizing tabs by seachern, and my plants are very healthy and grow very fast, including a nice thick carpeting of monte carlo.In contrast with another tank I have without "plant supporting" substrate, the tanks with the flourite grow plants much faster (with same brand lighting, and no Co2, just liquid fertilizer from seachern.)I'd recommend a light rinsing if you're in a hurry to get a tank setup, and definitely if you're adding it to an existing tank.The color is awesome and looks very natural, which is rare for a black substrate. I've bought a couple different brands I threw out because they just looked unnatural in black (one was obviously painted :/ )So I really like this substrate and have already bought more. I think you'll like it too as long as you're prepared to let the dust settle over a few days. :D

I had been looking for black gravel and studying reviews for a while before I finally chose this one and I am so glad that I did. Everything else I looked at with this size were simply painted white gravel and that was definitely not an option I wanted to choose. I followed the advice on another review for rinsing in a 5 gallon bucket and drying on a sheet in the sun for 3 hours. It worked perfectly! I rinsed one bag at a time in a 5 gallon bucket a little more than half full of water. Stirred it around and emptied the water. Repeated for a total of 6 times with each bag and spread it out on a sheet to dry for around 3 hours. When I set my aquarium back up with the new gravel there was absolutely no clouding in the water at all. So happy with the color and how it turned out. I used 3 bags for my 75 gallon tank but I think I may add a couple more in the near future. The black really makes everything else pop and shows off my goldfish. I would definitely recommend.

After reading reviews and researching this product for weeks, it became clear to me that the single most important thing was not rinsing the living crap out of it, but to cure it under the sun. So I did exactly that, spending less than 15 minutes total rising my three bags and ending up with a fabulous, cloud free tank.I filled a 5 gallon bucket halfway and poured one of the bags into it. You can see from the photos that the resulting goo is not something you would EVER under ANY circumstance add to an exiting tank, or a new one for that matter! I poured that mess of a clay soup out and refilled the bucket halfway. I did that about 5 more times until the water was 90% clear. I repeated that process twice more for the other two bags then spread the Flourite out on a fitted sheet.I must point out here that had I wanted, I could have easily kept rinsing until the gravel was crystal clear, but I did not.Anyway, after about three hours under the sun, I emptied it into two buckets. The Flourite was bone dry and had a million tiny particles in it so it was a bit dusty. I poured about a gallon of water into each pail to keep the dust down then added it to the tank. I then filled it five gallons at a time, pouring the water onto one of the rocks in my tank. I immediately added my plants and despite all the rustling of the gravel to get them rooted, there was no cloud. Yay!

This truly needs to be rinsed SEVERAL times before placing in the tank…even then, there will be a bit of cloudiness. Add water carefully over a dish to avoid lots of cloudiness. The water clears up in a few hours. My bag was new and sealed, and luckily mine didn’t have a lot of dust to rinse off.Consistency: I expected larger gravel size, but this is more of a sand with small gravel bits mixed together. Looks great in the tank! Hopefully it holds up over time. Used in a 6 gallon, and had about 3 lbs left over for a 2 in depth.

Produtos da marca seachem, vc pode comprar de olho fechado, pois até o momento, não conheço nenhum que seja ruim. Utilizo vários produtos da seachem, como ração clorella flakers, purigen, seagel, acid buffer, alkaline buffer, prime, stability, flourish e stress guard, todos muito bons e agora o substrato flourith black.

Arrivato in tempo, molto polveroso bisogna sciacquare

This is really good plants grow well and it does not make mess in tank like some others have put this in all my tanks

O produto não tem 16,5 kg tal como mensionado na descrição, tem apenas 7.5 kg como aparece na imagem do saco. Sinto-me enganado e lesado uma vez que é caso para a quantidade que tem, e desta forma não é suficiente para o que necessito.

Bonjour,Je l'utilise dans mes aquariums car il est vraiment super efficace, pour les plantes et les poissons, le ph est stable. Facile à entretenir Car la densité est parfaite, les grains tourne dans la cloche d'aspiration avant de retomber sans partir avec les déchets, ce substrat ne se d'élite pas contrairement à beaucoup d'autres de renoms et ça c'est important pour moi. J'ai acheté ce sac en complément pour une meilleure reprise de mes boutures de plantes que je mets en pot avant de les installer dans l'un de mes aquariums. Comme beaucoup de produits seachem c'est pas donné ( surtout ici ) mais la durée de vie ( 4 ans sans problème aujourd'hui ) en vaut le coût. Cordialement Christophe
