Rated 4 out of 5 by TheWookie Seems to work
I have split the box and used these in my 95g freshwater tank and in my FOLR salt tank while I sort out my sump situation (temporarily using a canister.) In both cases they seem to work well. On my heavily stocked fresh community tank, I used to consistently get .25 ammonia, 0 nitrite and 5 - 20 nitrate using the API drop tester. With the bioballs removed and the spheres installed, my ammonia has been 0 for three weeks, nitrite 0, however, nitrates have gone to 20-40 ppm. I guess the increased nitrate is a by product and ok as long as it won't go higher. I am a consistent water changer and filter cleaner every third or fourth weekend.
