Maintaining the cleanliness of an aquarium can be a demanding task. Acquiring the knowledge of properly cleaning an aquarium is a crucial ability for all fish owners.<\/p>\n

You might need to remove the fish, scrub off algae and dirt from the glass, vacuum up any leftover food or poop on the substrate, wipe down all surfaces in the tank with a special cleaner made for aquariums and then refill it with fresh water. It\u2019s hard to keep your aquarium looking great when you don\u2019t know what steps are required to do so.\u00a0<\/p>\n

With this guide, we will explore each step required to clean your tank properly. We\u2019ll discuss how much time and effort goes into keeping an aquarium clean as well as some tips for making cleaning easier on yourself. By following these instructions, you should be able to keep your tank looking good without spending hours doing so every week!<\/p>\n

Important Basics of How to Clean an Aquarium<\/h2>\n

It\u2019s important to observe your fish and their behaviors each day. This way you can more easily evaluate the health of your fish and any issues they might be having. This can help provide clues as to when your tank might need some extra attention. Besides basic daily observation, below are some basic questions around aquarium cleaning.<\/p>\n

How often do you need to clean a fish tank?<\/h3>\n

The frequency of tank cleaning depends on your tank, how many fish you have, and the specific requirements of each species. Heavily stocked tanks will need to be cleaned more frequently. Tanks with Oscars will need to be cleaned more frequently than tanks with Neon Tetras<\/a>.<\/p>\n

Other factors include your filtration system, amount of live plants, and amount of bio material<\/a> in your tank. If you clean a fish tank regularly, you will be more likely to notice any issues in time for timely intervention.<\/p>\n

So that puts the answer likely somewhere between once a week and once a month, depending on your set-up.<\/p>\n

Should I remove the fish while cleaning my fish tank?<\/h3>\n

Generally speaking, no. Sometimes a special situation may require you to remove the fish, but in general, we recommend against doing this. \u00a0If you make it a habit of removing your fish from the tank every time you clean it, they will likely become stressed and vulnerable to illness.<\/p>\n

Do I have to take all the decorations out of my tank?<\/h3>\n

No, you don\u2019t have to remove all the decorations in order to clean your tank. \u00a0It is a good practice to remove any dead or rotting material and prune your plants<\/a>. However, we do recommend leaving live plants and rocks in place. \u00a0This will help maintain the environment for your fish while you clean the tank itself, which will give them hiding places if they\u2019re feeling stressed.<\/p>\n

How long do you let water sit before putting fish in?<\/h3>\n

Historically, people recommended letting your water sit for at least 24 hours so the chlorine could evaporate. Now, most places use chloramine instead of chlorine in tap water. The catch is that chloramine doesn\u2019t evaporate which means you need to add a water conditioner to make the water safe for fish. Once your water is dechlorinated, it is safe for use immediately.<\/p>\n

What cleaning supplies do you need to get?<\/h3>\n

Benefits of Cleaning Your Fish Tank<\/h2>\n

Healthy fish create waste. Fish waste builds up over time, which negatively impacts the nitrogen cycle. \u00a0Over time, this may lead to algae issues and lower oxygen levels.\u00a0By cleaning your tank, you are helping to balance the environment in order to keep it safe for your fish.<\/p>\n

The list below outlines benefits you\u2019ll likely see by keeping your tank clean:<\/p>\n

Reduce Harmful Compounds<\/h3>\n

By cleaning your tank, you will reduce the amount of nitrate, nitrite, ammonia, and phosphates in your water. \u00a0These compounds are harmful to fish if present in high levels.<\/p>\n

High levels of these compounds will stress your fish, making them vulnerable to disease and promoting poor growth and color development. Changing the water in your tank can help you control these elements.<\/p>\n

Remove Decomposing Waste\u00a0<\/h3>\n

Fish produce waste. Some fish have bigger bio loads than others. For example, arowanas<\/a>, oscars<\/a>, and mollies<\/a> are bio load heavy, whereas tetras and chili rasboras<\/a> are bio load light.<\/p>\n

Over time, fish waste will decompose and create ammonia. \u00a0The longer this remains in your tank, the greater the risk of your fish becoming stressed or sick. By cleaning out your tank regularly, you will remove decaying materials that build up over time.<\/p>\n

If you don\u2019t clean regularly, your tank will look dull and dirty, especially with accumulated waste. Nobody likes a poopy tank, especially your tank inhabitants. Also, a dirty tank can be discouraging visually and it can also discourage behaviors like schooling behavior or hiding locations.<\/p>\n

How to Clean An Aquarium<\/h2>\n

Step 1: Get your Equipment Ready<\/h3>\n

Before you start cleaning, make sure you have your equipment ready. You don\u2019t want to get caught with a gravel vacuum full of waste and nowhere to put it so make sure you have everything ready to go before you get started.<\/p>\n

Step 2: Test the Water Quality<\/h3>\n

Before you begin cleaning, it is important to test your water. If your aquarium is newly established, your goal for the water is 0 ppm ammonia, 0 ppm nitrites, and less than 40 ppm nitrates. By keeping these compounds at these levels, you reduce the risk to your fish.<\/p>\n

If your aquarium is already established, focus on keeping the nitrate levels below 40 ppm. By understanding nitrate levels prior to the cleaning process, it will help give you an idea of how much water should be removed. If you\u2019re seeing other issues in the water test, you also might need a more in-depth cleaning.<\/p>\n

Step 3: Remove Algae<\/h3>\n

The next step is removing algae. This will help keep a clear view for checking out your beautiful fish tank. We recommend using an algae scraper<\/a> to scrub the tank walls. For thick algae, use the blade attachment. You can also use a gravel vacuum to remove algae and other decaying material from your substrate. Lastly, for algae growth on aquarium decor, rocks, any plants, you can use a clean toothbrush (we recommend dedicating one to this purpose!) to gently brush it off.<\/p>\n

\n\t\t\t\t\"Lasso
\n\t\t\t<\/a>\n\t\t\t\t\t<\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n

If your tank lid is covered in algae, rinse it off in the sink. Avoid soap or any other chemicals that would harm your fish if they got into the water.<\/p>\n

Step 4: Prune<\/a> the Plants<\/h3>\n

Next, remove excess growth from your plants. This helps promote healthy plants, and it also helps improve the visual look of the tank. There are many ways to prune<\/a>; we recommend using an aquascaping kit specifically for this purpose. Every plant species is different so it is important to adapt your pruning style to your species.<\/p>\n

If you have floating plants that have taken over the water surface, remove about 30% to 50%. This will improve light flow for your plants and oxygen levels for your fish.<\/p>\n

Step 5: Turn off Equipment<\/h3>\n

Before starting the water change process, turn off and\/or unplug all equipment. You\u2019re dealing with water and electricity so the last thing you want to deal with is electricity running through your water. Also, certain aquarium equipment, such as heaters and filters, are not meant to operate without water so you run the risk of damaging them if you run them without water.<\/p>\n

Step 6: Vacuum the Substrate<\/h3>\n

It is important to vacuum the substrate (sand, gravel, etc.) thoroughly for cleaning purposes. Lots of waste and debris accumulates in the substrate so you definitely don\u2019t want to skip this step. You need an aquarium-specific vacuum; you don\u2019t want to use a regular household vacuum for so many reasons!<\/p>\n

\"Cleaning<\/figure>\n

Vacuum approximately one-third of the substrate. Make sure to shift your decorations and hardscape around because debris tends to collect underneath them.<\/p>\n

Step 7: Clean the Filter Media<\/h3>\n

Filter cleaning is an important step. Think of your filter like your trash can that collects fish poop and other waste materials. Trash cans need to be emptied regularly, or they get too full and spill all of that nasty stuff back out into your tank! Or, they clog up and overflow all over your nice floors! Best to avoid both situations.<\/p>\n

For hang-on-back (HOB)<\/a> or canister filters<\/a>, simply remove the filter and wash it in the bucket of recently removed tank water. Do not use soapy water or tap water, just your tank water. For sponge filters<\/a>, remove the foam and wring it out multiple times in the old tank water bucket. Both soap and chlorine from the tap water will kill all your beneficial bacteria, so rinse off all of that gunk with your tank water.<\/p>\n

Step 8: Refill the Water<\/h3>\n

Time to refill your tank with fresh, clean water. Important things to note about adding new water to your tank. First, you want it to roughly match your aquarium\u2019s current temperature to avoid a temperature shock. Secondly, never add tap water straight into your tank. You will always need to add dechlorinator<\/a> to not shock your inhabitants.<\/p>\n

\n\t\t\t\t\"Lasso
\n\t\t\t<\/a>\n\t\t\t\t\t<\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n

Empty out the bucket of old tank water (great for plants so it doesn\u2019t go to waste!), and refill it with tap water. Add your dechlorinator into the bucket (dose on the bucket\u2019s volume so you get everything correctly proportioned). If you\u2019re maintaining a planted tank, you can also add fertilizer.\u00a0When you\u2019re ready, slowly add the water back into your tank to minimally disturb the substrate. You\u2019re going to kick-up particles, even with the slowest pouring, but don\u2019t worry! Things will quickly settle within an hour or so.<\/p>\n

Step 9: Turn on Equipment Again<\/h3>\n

Time to turn everything back on.\u00a0 If you have a heater, remember to adjust the temperature once all water is added back into your tank.<\/p>\n

Step 10: Wipe the Glass Clean<\/h3>\n

For a crystal-clear finish, wipe down the outside walls of the tank with aquarium-safe glass and acrylic cleaner. This will get rid of your fingerprints and any smudges along the way. Don\u2019t forget to dust the lid, light, and aquarium stand.<\/p>\n

Step 11: Enjoy Your Clean Tank!<\/h3>\n

Now that the tank is clean, it\u2019s time to enjoy your beautiful aquarium! Don\u2019t forget to regularly maintain your equipment and perform water changes moving forward. Cleaning is not a one-and-done operation.<\/p>\n

Fish Tank Cleaning Maintenance<\/h2>\n

In-between full fish tank cleans, we recommend some routine maintenance tasks to keep everything looking clean and beautiful.<\/p>\n

Daily Tank Maintenance<\/h3>\n

We might have scared you with the idea of daily fish tank maintenance but in reality, the list of to-do items is short. These chores only take a few minutes and will help you maintain your fish tank.<\/p>\n
