    Its a very good medium and very similar conceptually to AquaClear Bio Beads. Either is good in fresh or salt water (especially in sumps), but in a marine tank I add Purigen to the filter as welll. Alfagrog has a higher porous capacity, but Purigen can absorb detritus and toxins 5X as small. Alfagrog should not be used as a gravel though,as it has tons of hiding spots for dirt and detritus as well.

    Anal comments? lol. I’ve never used it but it looks very porous and small enough not to trap large debris so i’d imagine yes.
