Water Change Warnings

5 Warning Signs Your Aquarium Needs an Immediate Water Change | Hilary Jaffe

Is your aquarium trying to tell you something? While regular testing is the gold standard for reef keeping, your fish and corals often show physical distress signals long before you pull out the test kit. In this video, Hilary breaks down five "surefire" visual cues - from dulling colors and strange swimming behaviors to hidden algae spikes - that indicate your water parameters are drifting. You’ll learn how to perform a "white paper test" for water clarity, what "skeleton-showing" corals really mean, and why knowing your fish’s "normal" behavior is your best defense against a tank crash. Don't wait for a total system failure; learn these biological red flags and keep your aquatic environment thriving.
