5 Tips For Saltwater Aquarium Maintenance

5 Tips For Saltwater Aquarium Maintenance

Many people think that of all the pets you could have, fish is the easiest to care for. While you don’t have to take your fish for a walk, or give it a bath, you still have to know how to maintain the aquarium so that your fish are happy and healthy. Fortunately, saltwater aquarium maintenance isn’t very difficult.

Here are 5 tips on how properly maintain your aquarium.

Practice Proper Fish Feeding

When it comes to our own health, we are very careful with what we put into our bodies. The wrong kind of food could seriously put our health in risk. So it shouldn’t be surprising that the food you feed your fish is something you need to be mindful of. You want to create a balanced diet for your fish and coral, but there is a bit of a learning curve.

Aqaurium Fishes Eating

It’s important to understand that what may be good for one type of fish may not be suitable for another. To ensure you are feeding the inhabitants of your aquarium properly, you will need to do your research on the fish, the coral, and any other sea creatures you have living in your tank.

Check The Water Chemistry Of Your Aquarium

The allure of keeping an aquarium is that you can have a colorful tank with some of the most beautiful fish you can find. The downside to this is that you need to be vigilant about checking the chemistry of your aquarium.

If you’re thinking about getting a new fish, consult the aquatic expert to learn what are the best levels of nitrate, nitrite, pH, and ammonia for the fish you want. If there is a significant difference between what is best for the fish and the chemistry of your aquarium,  your new fish is going to require more time to acclimate.

Adding additional 'live filtration' can be a good idea, in particular the growth of coralline algae.

Maintain Proper Temperature

You know yourself that when the temperature is chilly, you want to bundle up or turn up the heat. When it gets too warm, you’ll wear shorts, open the windows, or even turn on the air conditioning. You may even put some ice in your dog or cat’s water bowl to help them cool off. You can’t do that with your fish.

Water Heater In Aquarium

When the water in the fish tank changes temperature, it can be a big effect on the ecosystem in the tank – even if it only changes by a few degrees. To make sure your fish aren’t freezing (or boiling), you’ll want to get a top rated aquarium heater and check it each day to make sure it is stable and holding between 75 to 78 degrees for a reef aquarium, or 78 to 82 degrees for a tropical saltwater fish aquarium.

Use The Right Filtration System

For proper aquarium maintenance, it is important that the filtration system is in proper working order. If you are using a biological filter like a live rock or live sand, you don’t have to do much.

However, if you are using canister style filters, you’ll want to use a turkey baster to blow away built up debris from crevasses. You can also use protein skimmers that will remove foam from the top of your water.

Clean The Aquarium

It is essential that you replace at least 25 gallons of the water every month. Not only do you want to change at least some of the water, but you also want to clean the glass and watch for algae buildups. All of these things will help boost the ecosystem in your aquarium, while giving you a clear and unobstructed view of your colorful fish and coral.

Aquarium Inside Cleaning

Purchasing a gravel cleaner and algae scrapper is a good idea and will help you maintain a clean healthy aquarium.


Creating a beautiful saltwater aquarium takes a decent amount of planning, investment, and patience. You don’t want all that effort to go to waste by not maintaining your aquarium! While fish may not require as much care as a dog or a cat, there is still some work involved.

With proper maintenance of your aquarium, you can be assured that your fish are living in a healthy ecosystem that will encourage the fish (and good bacteria) to thrive and do well.
