Tank Treatment Guide

Explore eight common water and system problems. Start with measured conditions, investigate the cause, and plan corrections suitable for the animals in your tank.

What this tool does

  • Explore condition-specific signs, possible causes and check-first actions.
  • Read source-linked treatment and correction context without universal medication schedules.
  • Record observations and know when to contact a fish-health professional.

Explore the references

  • Ammonia Spike

    Interpret the kit result with pH and temperature, then investigate waste and biofilter capacity.

  • Nitrite Spike

    Nitrite can impair oxygen transport even when dissolved oxygen is adequate.

  • High Nitrates

    Check the measurement, source water and maintenance trend against species-specific needs.

  • Cloudy Water

    Separate suspended particles from a possible microbial bloom, and test before assuming harmlessness.

  • Algae Bloom

    Identify the type of growth and assess light, nutrients, waste and oxygen.

  • pH Crash

    Confirm an unexpected drop and investigate buffering, ammonia and gas exchange before correcting pH.

  • Oxygen Depletion

    Restore circulation promptly while investigating why fish are struggling to breathe.

  • New Tank Syndrome

    Use measured ammonia and nitrite trends to judge biofilter capacity, rather than age or clarity.
