A slow upward drift of 0.2 to 0.4 pH units over 48 hours indicates healthy vegetative growth. Rapid overnight spikes above 6.5 indicate…

  • Hydroponic Reservoir Maintenance: When to Dump Your Tank

    ByFaisal Habib

    Home > Hydroponic Systems > Hydroponic Reservoir Maintenance: When to Dump Your Tank Last Updated: July 2026  |  Reviewed for nutrient salt accumulation kinetics, root exudate oxidation, and biofilm sanitation protocols Quick Answer: You should completely dump, clean, and replace your hydroponic reservoir water every 10 to 14 days, or whenever the volume of top-off water added equals the total capacity of your tank (the 100% Top-Off Rule). Continuous top-offs without dumping cause toxic salt accumulation (sodium and sulfate spikes) and unbalanced NPK ratios. Calculate exact mineral refill dosages using our EC to PPM Calculator. Difficulty: Beginner to Intermediate DIY Maintenance Frequency: Every 10 – 14 Days Time Required: 25…
