Are they count as water conditioner?

2 years ago
API Stress Zyme is not a water conditioner. We would recommend to use a water conditioner like API Stress Coat or API Tap Water Conditioner as well to the API Stress Zyme.

Does anyone know why a lot of these products have instructions that say use this much for every 38L of water? I mean why can't they just include a per gallon amount too? It's kinda annoying to have to recalculate it myself.

4 years ago
Simple answer: The directions on the label state use 5ml per 10 gallons. The bottle cap is incremented 5ml and 10 ml.

Stress zyme and quick start

Thank you for your question. The Stress Zyme would be similar to the Quick Start. We recommend using one or the other but not both together.
