Natural Cleaning Solutions
Vinegar Solution
White vinegar effectively removes hard water stains and mineral deposits:
- Mix equal parts white vinegar and water
- Apply to affected areas with a soft cloth
- Let sit for 10-15 minutes
- Scrub gently with an algae pad
- Rinse thoroughly with clean water
Baking Soda Paste
For stubborn algae stains:
- Make a paste with baking soda and water
- Apply to problem areas with a soft brush
- Let sit for 5 minutes
- Gently scrub and rinse completely
Step-by-Step Cleaning Process
1. Partial Water Change
Remove 20-30% of tank water weekly using a siphon. This helps maintain water quality without shocking your fish.
2. Gravel Cleaning
Use a gravel vacuum to remove debris from substrate without disturbing beneficial bacteria colonies.
3. Glass Cleaning
For interior glass, use an algae pad or scraper. For exterior surfaces, a natural glass cleaner works well.
4. Filter Maintenance
Rinse filter media in removed tank water to preserve beneficial bacteria. Replace media as recommended by manufacturer.

Preventive Maintenance Tips
Lighting Control
Limit tank lighting to 8-10 hours daily to prevent excessive algae growth.
Proper Feeding
Feed only what fish can consume in 2-3 minutes to reduce waste accumulation.
Live Plants
Add fast-growing plants like hornwort or anacharis to compete with algae for nutrients.
