Aquarium Maintenance Guide

Aquarium Maintenance Guide

A well-maintained aquarium ensures healthy fish, thriving plants or corals, and clear water. Following a regular schedule prevents problems before they start and keeps your aquatic ecosystem in balance.


Daily Routine

  • Observe Fish Behavior: Watch for changes in swimming, feeding, or hiding patterns. Early detection of disease (spots, clamped fins, labored breathing) is key.

  • Feeding: Feed small portions that fish can finish within 2–3 minutes. Remove uneaten food.

  • Check Equipment: Confirm heater, filter, air pump, and lights are functioning.


Weekly Maintenance

  • Water Change: Replace 10–20% of tank water with fresh, dechlorinated water.

  • Glass Cleaning: Wipe down aquarium glass to remove algae build up. Magnet cleaner and algae scraper helps. 

  • Gravel Vacuuming: Siphon debris and waste from substrate to prevent nutrient buildup.

  • Quick Check: Ensure fish remain active, plants look healthy, and no foul odors develop.


Monthly Routine

  • Filter Care: Rinse filter media in old tank water (not tap water) to preserve beneficial bacteria. Replace media only if clogged or deteriorating.

  • Water Testing: Test for nitrate and phosphate levels.

    • If rising steadily → Increase water changes or improve filtration.

    • Aim for balanced nutrient export (daily feeding) vs. nutrient import (weekly water change).

  • Fertilizer (Planted Tanks): Add root tabs or liquid fertilizers if plants show nutrient deficiencies.


Bi-Yearly Routine (Every 6 Months)

  • Filter Impeller Check: Remove and clean the impeller to maintain efficient water flow.

  • Equipment Inspection: Check seals, hoses, and tubing for wear and leaks.


Key Tips for Success

  • Consistency is more important than heavy cleaning. Small, regular tasks prevent major issues.

  • Always treat new water with a conditioner before adding to the tank.

  • Avoid overfeeding—it is the leading cause of excess nutrients and algae.

  • Keep a maintenance log to track water changes, filter cleanings, and test results.


✅ Following this guide will help ensure your aquarium stays clean, your fish stay healthy, and your ecosystem thrives long-term.
