Product arrived as described. Very little powder and very few garbage stones. My thermo 600 took all x4l. Will update x4 months from now on performance changes. Replaced ceramic rings and sintered glass bio balls from Ehiem. Make sure u wash thoroughly and soak for 24hrs to keep the floaters to a min. Update; working well in my 600, all my values are 0 and the water is crystal clear with just a little yellow due to wood in tank. All x4l went into my 600, flow is good with the 45ppi ring sponges on pre filter. Taken x7 weeks for these results. PH is stable at 7 to 7.1 Great stuff but still expensive! Read more

I was having some issues with the cycle crashing in my aquarium after medicating the fish for an ich outbreak. This bio media helped maintain the cycle perfectly after getting it back up and going. I’ve tried other ceramic type bio media similar to this in the past but this one is far superior. It never needs replacement so the cost is well worth it. Read more

Porosità altissima. Pochi ‘’sassolini’’ sono sufficienti per garantire un ambiente ottimale. E poi hanno una durata infinita. Read more

I've been using this for a few months instead of a carbon filter in the Kmart $11 canister filter. I can't say if it's better or worse as I also started using seachem stability. Together they have made a difference to the health of the tank as the fish seem happier and water PH isn't fluctuating as much ( I'm not sure if that's scientific from using these two products or a coincidence).
