It is excellent for the aquarium.** A: Yes, mix it 50/50 with a good compost. It has so many good plant nutrients. I also water my plants with my old aquarium water with stunning results. **Q: Can you just put this in your tank?** A: Yes you can.

But you can use the tetra active just like you would stones in your tank. **Q: hello all, is this shrimp safe? I really don't want this stuff leaching nitrate into the water column.
