✅ Daily Maintenance
These quick daily checks help prevent problems before they start.
-
Feed fish: Only give what they can eat in 2–3 minutes to avoid leftover waste.
-
Observe fish behavior: Look for signs of stress, illness, or unusual behavior.
-
Check water temperature: Most tropical fish prefer 76–82°F.
-
Ensure equipment is working: Make sure the filter and heater are running properly.
🗓️ Weekly Maintenance
Routine weekly tasks keep your water parameters stable and the tank clean.
-
Test water quality: Check for ammonia, nitrite, nitrate, and pH using a reliable test kit.
-
Top off water: Refill evaporated water with dechlorinated tap water.
-
Remove uneaten food & waste: Use a gravel vacuum or net to clean the bottom.
-
Clean algae: Use a magnetic scraper or algae pad to keep the glass clear.
📅 Biweekly or Monthly Maintenance
Set aside time every few weeks for a deeper clean.

Change 25–30% of the water: Use a gravel vacuum to remove built-up debris.
