> 3 dayBought for my aquariums to replace biomedia my filter came with. Along with regular partial water changes the ammonia and nitrites stay at 0 so no complaints here.

> 3 dayI purchased this and the DeNtrate one and the only difference seems to be the size of the stones. If you are putting this in a refillable media cartridge, then the DeNitrate is probably better. But, if its going in a mesh bag or something similar, then this Bio Media would be my preference. Both seem to work just as well.

Greater than one weekIve only had 2 liters of this in my reef tank for 2 months so chemically I can not say if its working but stability with moderate bio-load has been good. Only a few dark pieces found in each container. Im not convinced these are harmful but I took them out for a quarantine tank. Will purchase additional.
