Ordered two each of 2-liter size. Got two each of 1-liter size container. Shameful in my opinion! **Q: How do I use this product with a wet/dry filtration system?** A: Put it in a bag near the water intake tube, and make sure that the bag is fat (mine holds a whole jar) to keep the center protected from oxygen. You want a mild movement of water but not enough to disturb the inside bacteria. The outside bacteria will like oxygen, but to remove nitrates, you also need to colonize anaerobic bacteria. I have kept nitrates a zero for months now with no water changes, BUT I also dosed the tanks with BioDigest bacteria, which has both aerobic and anaerobic bacteria to eat nitrates. That combination seems to work well. **Q: what is the difference between this and matrix?** A: It’s the same it’s just smaller stones. No difference **Q: What filter can I use this in that is 50 gph or less rate?** A: You can use any canister filter with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really works. *by J***Y on June 13, 2026* Good product have used it for yrs.
