Quick answer

Daily, Weekly, Monthly: An Aquarium Maintenance Schedule

Good aquarium care is a rhythm of small tasks: a quick daily check, a weekly partial water change and glass clean, and a monthly deeper service of the filter and equipment. Consistency matters far more than intensity. Never do a huge overhaul all at once, as it can crash the beneficial bacteria and shock your fish and shrimp.

Decide in 60 seconds

Daily (2 minutes)

Each day, feed appropriately and simply watch. Count your fish and shrimp, check everyone is swimming normally, eating and free of visible marks or rapid breathing. Glance at the thermometer to confirm the temperature is stable, and check that the filter and heater are running. Remove any obviously uneaten food after feeding. This daily habit is how you catch trouble while it is still small.

Weekly (20-30 minutes)

The weekly routine is the backbone of a healthy tank. Test the water for ammonia, nitrite and nitrate so you can act before problems show on the fish. Then do a partial water change, typically 15 to 30 percent, using a gravel siphon to lift debris from the substrate. Wipe algae off the glass, top up with dechlorinated water matched to tank temperature, and check that plants and decor are in order.

A weekly partial water change with a gravel vacuum is the core of good maintenance.

Monthly (30-45 minutes)

Once a month, give the system a deeper service. Rinse or gently squeeze filter sponges and media in a bucket of old tank water, never under the tap, so you keep the beneficial bacteria alive. Replace only worn-out mechanical media, and stagger any media swaps. Check the heater, filter flow, air pump and lighting, trim and thin plants, and clean the tank lid and light cover where evaporation leaves residue.

Keep a dedicated kit ready so routine care takes minutes, not effort.

Shrimp and sensitive tanks

Shrimp and delicate species need extra gentleness. Keep water changes smaller and very steady, and always match temperature and use a good dechlorinator, since shrimp react badly to swings and to any copper, including in some medications and tap water. Go slow when topping up, and avoid disturbing the biofilm shrimp graze on. For shrimp tanks, stable parameters beat pristine sparkle every time.

Living context by region

This guide is written for multi-region English readers (US/UK/AU/NZ/CA/EU and more). Where climate, products, or vet access differ, prefer local veterinary advice and local product labels. Use metric first; keep °F/lb in mind for North American homes.

When to call your vet

• Signs are getting worse over hours, not better

• Pain, persistent vomiting/diarrhea, or neurological signs

• You needed force or guesswork to keep going at home

Common mistakes

• Waiting because the animal 'still looks okay' while prey species hide pain

• Changing five variables at once so you cannot tell what helped

• Copying drug doses from social media

• Skipping species-appropriate husbandry while buying more gadgets
