## Questions & Answers

**Q: I have installed canister filter. Can I use thi product ?**
A: Adding a canister filter will definitely help in filtration however you need to understand that it will take 2-3 weeks for beneficial bacteria to colonize in the biological media of your canister filter to give optimum results. Stress Zyme will add those beneficial bacteria so definitely it will reduce a cycle time. Irrespective of this, it needs 2-3 weeks to establish a good biological cycle. If you have a right biological media then it will yield results in long term. It is a catalyst.

**Q: What is the expiry date of this product**
A: It's should be printed on the bottle.
