Welcome to Dose My Tank, a dedicated resource for aquarium hobbyists looking for precision and safety in their tank maintenance routines.
The nitrogen cycle and chemical balance of an aquarium are delicate. Most dosing instructions provided by manufacturers are based on "Gross Volume"—the total capacity of the glass box. However, real-world aquariums contain substrate, rocks, wood, and equipment that displace water, often reducing the actual water volume by 15-30%.
Our mission is to provide a simple, accurate tool that calculates Net Water Volume to prevent accidental overdosing, ensuring a healthier environment for your fish, shrimp, and plants.
As passionate hobbyists ourselves, we found that manual calculations for complex dosing schedules (like eSHa courses or Seachem Excel) were prone to human error. We built this hub to automate those calculations, providing clear, easy-to-follow instructions tailored to your specific tank dimensions.
While our tool uses industry-standard displacement factors and verified manufacturer data, every aquarium is unique. We always recommend observing your livestock closely after any chemical addition. Our tool is designed to be a helpful guide, but the ultimate responsibility for the health of your aquarium lies with the keeper.
