Perfect for AQUARIUM use. I have not found a like product in pet stores, but thought to try this Pool/Spa rare earth. (Food grade products don't cut it). It does 2 microns filtering, and works fine with my old VORTEX diatomaceous earth filter.Cost wise it's a bargain, and now I don't have to skim on a filter fill with my previous limited supply.

I have a salt water pool and have purchased this exact item several times at pool stores and the price on Amazon is typically a much better value. I prefer to buy DE in boxes rather than bags because the bags of typically unwieldy and make a bigger mess. This product works perfectly through my Hayward filter system and I rarely get algae. Thumbs up here!
