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

01-27-2026 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. ______________________________________________ ⚠️ Products In This Video ► Tropic Marin Compact Lab - Essentials Test Kit (5 Parameters) - https://www.saltwateraquarium.com/compact-lab-essentials-test-kit-5-parameters-tropic-marin/ ► Spot Check Marine Water Test (Single Test) - https://www.saltwateraquarium.com/spot-check-marine-water-test-single-test-saltwateraquarium-com/ ► ATI ICP-OES Pro Lab Water Test Kit (w/ Prepaid Shipping Label) - https://www.saltwateraquarium.com/ati-icp-oes-pro-lab-water-test-kit-w-prepaid-shipping-label-ati/ ► Hanna Instruments HI98319 Salinity & Temperature Tester - https://www.saltwateraquarium.com/hi98319-salinity-temperature-tester-hanna/ ► Python (50 Foot) No Spill Clean & Fill Aquarium Water Change Kit - https://www.saltwateraquarium.com/50-foot-no-spill-clean-fill-aquarium-water-change-kit-python/ ► Sicce Ultra Zero Utility Water Mixing Pump - https://www.saltwateraquarium.com/ultra-zero-utility-water-mixing-pump-sicce/ ► Flipper EDGE Standard Magnet Cleaner (up to 1/2" Glass) - https://www.saltwateraquarium.com/flipper-edge-standard-magnet-cleaner-up-to-1-2-glass-flipper-cleaner/ ► Boyd ChemiClean - 2 Gram Powder - https://www.saltwateraquarium.com/chemiclean-2-gram-powder-remove-red-slime-algae-cyanobacteria-boyd/ ______________________________________________ Website - https://www.saltwateraquarium.com Follow us on Facebook - https://www.facebook.com/swaqdotcom/ Follow us on Instagram - https://www.instagram.com/saltwateraquariumdotcom/ Follow us on TikTok - https://www.tiktok.com/@saltwateraquarium.com ______________________________________________ 📩 If you have a request related to equipment in this video, or this video in general, email - [email protected] #saltwateraquarium #swaq
