You'll need to perform regular water changes to keep the water in your fish tank clean and healthy. A good rule of thumb is to change 10-15% of the water each week.

Step 3: Keep an eye on the temperature

Your fish tank's water temperature should be between 74-82 degrees Fahrenheit. Use a thermometer to check the temperature of the water regularly.

Overfeeding your saltwater fish can lead to several problems, including water pollution and health issues for your fish. So, ensure only to give them as much food as they can eat in a few minutes.

Saltwater tank cleaning tips

Step 1: Use a gravel vacuum

Use a gravel vacuum to clean the substrate in your fish tank. This will help remove any debris and waste accumulated on the bottom of the tank.

Use an aquarium-safe glass cleaner to clean the glass of your fish tank. Also, ensure to avoid using cleaners containing ammonia or other harmful chemicals.

Step 3: Remove algae

Algae can quickly take over a saltwater fish tank if it's not removed regularly. Use an algae scraper to remove it from the glass and decorations.

Quarantine new fish

Before adding new fish to your fish tank, you'll need to quarantine them for at least two weeks. Thus, this helps to prevent the spread of disease and parasites.
