Biohome BioGravel Aquarium Filter Media (2 Pound)

I went looking for this stuff after stumbling on the video of a Biorb filtration upgrade and converted both my 4 gallon biorb and the new 16 gallon one I ordered but hadn't set up yet. The first pic is the 16 gallon set up as a blackwater nano tank, and the second is the 4 gallon. Both with the filtration, sponge and biomedia upgrades under the larger rocks, decor/wood. The changes have been a game changer for me and I am completely in love with this media and plan on slowly upgrading all of my Betta and nano biorb set ups (I have a weird obsession with the tanks for some reason) with it one tank at a time as it is a bit pricey compared to other options, but it is worth the initial cost with the money saved in the long run on filter cartridges and the annoyance of having to practically take the tank apart just to change them. The amount of filtration power that it gives is amazing!

Works exactly as advertised

Geliefert wurde 1 Pfund wie bestellt. Lieferung ging sehr schnell und war ordentlich verpackt. Nun zur Wirkung.Biohome ist gesintertes Glas und somit sehr porös, es bietet eine extrem große Oberfläche auf denen sich die guten backterien ansiedeln können und die Qualität des Wassers im Aquarium um einiges verbessert. Natürlich kommt es dann noch auf die Durchflussgeschwindigkeit des Filters an. Je langsamer das Wasser durch das Biohome strömt umso besser können die backterien ihre Arbeit tun.Ich kann das Produkt uneingeschränkt empfehlen und werde es auch immer wieder kaufen weil es einfach nichts besseres gibt.

Received slightly less than the stated weight.

This is the best there is but you don't get much for your money. I wish I would have measured but I would say about 2 American cups of gravel. I watched pimp my filter #49 by Pondguru on Youtube, to upgrade my BiOrb filter so I didn't have to use the sharp ceramic substrate that BiOrbs come with. I have the 4 gallon tank and after cutting out the pond foam and placing it in my tank, I then poured in one 2 lbs bag of this, and it wasn't enough. I just ordered a second bag which will do the trick. This substrate is expensive but from everything I've read, it is worth it with good bacteria and filtration., great for shrimp and plants. It is impossible to get a clean tank with BiOrbs substrate and I've gone through a lot of fish and shrimp because cleaning the substrate is a nightmare with the ceramic substrate. Why doesn't BiOrb get this right?
