Welcome to Aquarium-Modeler.

Thank you for caring about your fish.

This website exists to save lives, fish lives, by enabling you to model the levels of stress and harmful ammonia-based chemicals in your aquarium. For many people maintaining an aquarium is all too similar to playing Russian roulette. Without understanding the invisible stresses that your fish experience, you leave their fate to chance. This website offers you the first-ever, personalizable and dynamic model of the chemical stresses in your aquarium. This can help you can make more intelligent decisions about how to cycle your tank and when to conduct water changes so as to vastly reduce needless fish loss.

If you're new to the aquarium hobby or would benefit from a refresher on the nitrogen cycle, please check out the Why page before using the model on the What page. If you're technically inclined, visit the How page. Feel free to send in improvement suggestions (or scathing critiques) to the address listed in the Who page.
