How often should I test reef tank water parameters?

Quick Answer

Most reef tanks need weekly core testing, with more frequent checks in new systems, after dosing changes, or when corals show stress.

Test reef parameters more frequently in new tanks and after major changes. Check salinity and temperature often, then monitor alkalinity, calcium, magnesium, nitrate, and phosphate on a repeatable schedule. Use test kits and log trends in the ReefBay app. Test reef parameters more frequently in new tanks and after major changes.
