Terms of Use
By using the Reef Stability app or this website, you agree to these terms. If you don't agree, please don't use them.
What Reef Stability is
Reef Stability is a tool for tracking reef aquarium chemistry and calculating dosing. It provides information and estimates to help you make your own decisions. It is not professional or veterinary advice.
Dosing guidance — please read
Reef chemistry varies from tank to tank, test kits have error, and a wrong dose can harm or kill livestock. The app's calculations and recommendations are guidance based on published chemistry and your own inputs — not a guarantee. You are responsible for what you add to your tank. Always double-check against your own testing, dose conservatively when unsure, and treat the safe-change limits as limits. We show our sources so you can verify — please do.
No warranty
The app and website are provided "as is," without warranties of any kind. We do not warrant that they will be error-free or that any result will suit your tank.
Limitation of liability
To the extent permitted by law, we are not liable for any loss or damage — including to livestock, equipment, or your tank — arising from use of the app, the website, or the calculators.
Your content
Your logged data is yours. We claim no ownership of it.
