## Questions & Answers

**Q: Does this treat ich?**
A: “MaracynOxy successfully controls fungus infections caused by Saprolegnia, Ichthyosporidium…” The label states it does.

**Q: The bottle says "treats". Is this, then, something you feed them?**
A: No. "Treats" as in treatment. This is a liquid containing sodium hypochlorite. Its for killing fungus blooms in the tank, and fungal infections on fish. You will either add it to your tank, or place the fish in a separate tank and add it there for treatment.

**Q: Do I have to  pull filtration ?**
A: Yes you do for it to work properly

**Q: Does this product color the water or stain in any way?**
A: I've used this product on saltwater fish. I've only ever used it in a quarantine tank so as to minimize the impact to corals and inverts. No coloration observed.
