How to Safely Clean Your Tank and Aquarium Decorations

Keeping your aquarium clean is more than just a matter of aesthetics – it also has an impact on the water quality in your tank which directly affects your fish. To keep the water quality in your tank high, you should clean your tank decorations on a regular basis.

To keep your community of fish and invertebrates happy and healthy, you need to maintain a clean tank so that your water quality will always remain high. And even though a lot of people think that they need to remove all of the water from the tank, the truth is that you don’t have to do that unless the tank is in really poor condition. Keeping most of the water in the tank will actually help in maintaining the right level of good bacteria that are necessary for a healthy aquarium.

Just follow the steps below to clean your tank easily and efficiently. Be sure to do this on a regular basis to keep your aquarium looking beautiful and your animals healthy.

  1. Using an algae pad, you can clean the insides of the glass walls of your tank. There are a lot of different algae scrapers to choose from, but the right one will help remove any algae that’s stuck onto the glass. If there is quite a bit of stubborn algae on the glass, you can use a razor blade instead (but use a plastic one if your tank is acrylic).
  2. Clean your decorations by following the instructions below. Our tips will help you get this step done in no time!
  3. Using a water siphon, you can easily clean underneath your gravel, sucking up any debris that has collected down there over time. To make sure that you are getting everything, make your way across the tank slowly and deliberately, ensuring that you are covering every area.
  4. Next, you can clean the outside of your tank, but make sure to use a product that is designed for use on aquariums in order to rest assured that it is safe. You can even take a natural approach by using a household product like vinegar. It is not a good idea at all to use toxic glass cleaners or lime cleaners. No matter what, you are cleaning the outside of your aquarium, including the outside glass, the top of the tank, the hood, etc., so you shouldn’t be getting any of the solution into the fish tank water.
  5. Add back the tank decorations that have been cleaned. And also prepare the appropriate amount of water to add back to the tank, as the process of siphoning the gravel will end up removing some water from the tank. Remember, though, that you should really only be replacing up to 20% of the water in your tank, so you don’t want to overdo it and remove too much.

Note: It might not be a good idea to clean out your filter when you are doing a tank cleaning, as that could cause an imbalance of the beneficial bacteria in the tank. Therefore, experts recommend waiting a couple of weeks before doing a filter cleaning. Keep in mind that how you maintain your filter will also depend on the type of filtration system that you are using.

You already know that regular maintenance is crucial when keeping a fish tank- not only it will make your prized aquarium look spotless, but it also ensures that the fish and the plants in it thrive and stay healthy.

They have to be both efficient in what they do and deemed safe and non-toxic. These are our choices when it comes to the best fish tank cleaning tools and products:

Anything that you put into your aquarium could have an impact on your water chemistry and water quality. That means that if you clean your tank decorations with soap and don’t rinse them properly, the soap could change the conditions in your tank and it might have a negative impact on your fish. This is why you need to be careful about how you clean your tank decorations. To clean your aquarium décor safely, follow the steps below:

  1. Remove your tank decorations one at a time for cleaning. If you clean out the whole tank, you could cause your fish to become stressed, which will increase their risk for getting sick.

  1. Place the decoration in your sink and run hot water over it for two to three minutes. This will help to cut through accumulated algae and make the cleaning process easier.
  2. Make a 5 percent bleach solution by mixing about 4 teaspoons per 2 gallons of water.
  3. Pour the bleach solution over the item or place the item in a bucket filled with the bleach solution. Allow it to soak for two to three minutes.
  4. Use a toothbrush or bristle brush to scrub any algae and debris off the item.
  5. Rinse the object thoroughly in cool water for about 5 minutes to remove any traces of bleach.
  6. Fill another bucket with warm water and treat it with a dechlorinating agent.
  7. Add the cleaned item to the bucket and allow it to soak for 15 to 20 minutes before rinsing it again and then placing it back in the aquarium.

By following these instructions you can safely clean the objects in your aquarium with putting your fish at risk. Just be sure to only clean one large object (or several smaller objects) at a time so you don’t stress out your fish or kick up a lot of debris in the tank. You should also avoid cleaning your filter and your tank objects at the same time because you don’t want to kill off too many beneficial bacteria or you tank might re-cycle and that could kill your fish.

If the lighting in your tank is too high or if there is an abundance of nutrients (often due to infrequent water changes) you are likely to have algae problems. The best way to prevent excessive algae growth is to limit your tank lighting to 10 to 12 hours per day and to keep your aquarium out of direct sunlight. In addition to taking these precautions you can also reduce your tank cleaning requirements by using low-maintenance décor options. Fake plants and artificial driftwood can look good in your tank without increasing your tank maintenance duties – they don’t need any special lighting or substrate and they won’t change your tank water chemistry. It also doesn’t hurt that artificial tank décor options are usually much less expensive that artificial options.

Keeping your aquarium clean is essential for the health and wellness of your aquarium fish but you must strike a balance between cleaning often enough and cleaning too much. Your best bet is to set up a maintenance schedule for your weekly water changes and to correlate that with your décor cleanings. Cleaning one large tank object per week when you perform your water change will ensure that your tank stays clean without putting your tank at risk for re-cycling.
