Levi Gibbs: There are a lot of these ceramic pieces in this box and work great as media filter in the tank!

J. Ong: Bought two boxes and total pieces for the two boxes came at 219 pieces which is about 110 pieces per box. No where near the 140 pieces claimed in the box and also even less than other people reported having less pieces in their as at least they were getting over 120 pieces each.

J lJ l: Although many other reviewers are correct about the rings being more solid than porous, these are still great for bio media if you wanna get a little creative.

I cut small mesh bags into the shape of whatever filter im installing it for, move the rings into the direction of the water flow and line them up neatly. They have consistently helped with lower nitrate levels, seeding new tanks and also work as a course filter. Cleaning them is easy as well, just take them out, toss them around some aquarium or treated water and line them back up.

Of course I still recommend an actual bio filter like a bio sponge, but if you're here looking for an extra boost, this will 100% be what you're looking for, and is much cheaper than other alternatives.

P Shif: A product like this is very hard to review unless it was the only media in the filter.

For my new cannister filter on my equally new 75g aquarium I decided to be diverse with the media to try and coax every possible type of bacteria. I added a whole tray of Matrix and a tray of this and bioballs together. I keep all the media in bags because it wedges in between things and makes cleaning harder. Here, all that is needed is a shake and rinse in a bucket of aquarium water and it is clean.

Many reviewers mentioned that it is not porous like other media. This is true. It appears smoother but if you look at it there is texture where the bacteria can grow. Because I also used the very porous Matrix and also have porous lava rock in the tank, this has a different surface area will hopefully attract a different type of bacteria long term to help out.

So far the cycling has been slow. Part of this was a low PH issue I caused. It took a bit over a week for nitrites to show and the ammonia to drop. I am using ammonia drops and dosing over 2ppm. That simulates a fairly high bioload so it takes longer than a single fish but is more humane and will allow a larger number of...

Israel Rojas: En general me han recomendado este material filtrante pero no vi ninguna mejoría en mi acuario, lo uso en un filtro económico marca lomas, no he notado ninguna mejoría o algo que me haga recomendarlos sin embargo tampoco empeoro la calidad del agua así que creo que es una opción a probar

CNH: I have used these in the past with other tanks with great success and again purchased these to go in a new canister filter. Simply put them in one of the trays and leave them alone. I place them after the foam filters so they don't tend to get too dirty and before the purigen. If needed it is simple to rinse them in some tank water (do not rinse in sink water or you will kill your biological filter!) If you must replace them (which I don't know why you would) then do half at a time, that way you can rebuild your biological filter without crashing it and needing to recycle. This most current package seems to have more of the pieces stuck together than in the past. Cannot separate them without breaking them. Not sure that it's a problem really . . . the diminishment in surface area is minimal, but perhaps if you had a small area you needed to fill with them it might take more space? Great option as a bio-bed for your good bacteria!
