A large part of keeping your fish healthy is ensuring that their habitat remains healthy. Regular maintenance is key to keeping the aquarium environment safe. One roadblock for aquarium owners is knowing what maintenance they should perform. Experts may disagree on the specific points of aquarium maintenance, but everyone agrees that following a regular routine of any kind is better than no maintenance at all. This is my recommended routine aquarium maintenance plan.

Why Do Maintenance?
Often aquarium owners don't give much thought to maintenance. After all, they have a filter, and some bottom feeding fish to pick up stuff that falls there. So what else is needed? Some will cite the fact that nobody is cleaning the rivers, lakes and oceans, and they do fine. So why clean the aquarium? That's actually a good question. Mother Nature is not idle, she does a pretty good job of cleaning things up in the great outdoors. Lakes, rivers and oceans are large bodies of water that have currents and waves circulating the water. Rain falling adds fresh water, and live plants produce oxygen while absorbing carbon dioxide. The sheer volume of water also serves to dilute any harmful toxins.

Unlike bodies of water in nature, an aquarium is a relatively small amount of water. Add to that the fact that it is a closed system, and it becomes quite different than a habitat in nature. Nothing goes into or out of the tank unless you have a hand in making it happen. Filters certainly help, but if not maintained filters become clogged and can cause more harm than good. Meanwhile fish continue to produce waste, uneaten food decays, and potentially harmful byproducts slowly build up. The only way an aquarium will remain clean is if you take the time to perform maintenance on a regular basis. Otherwise, over time the habitat will become less and less healthy for the fish.

Frequency of Maintenance
It is neither practical, nor healthy, to clean every surface in the aquarium on daily or even weekly basis. For that matter, it's never wise to clean everything at the same time. To minimize the impact cleaning has on beneficial bacteria, cleaning of colony rich areas, such as the filter and the substrate, should be staggered. If the bacterial colonies are disturbed too much, it can disrupt the nitrogen cycle enough to cause a spike in ammonia and/or nitrites. For that reason, it's also wise to test the water a few days after a significant cleaning, to ensure nothing is amiss.

Daily - Do a quick visual check of the aquarium to ensure the filter is running at full strength, the lights are functioning properly, and any other equipment you have is running normally. Check the temperature to ensure it's in the proper range. Count the fish and observe them to see if they appear healthy. A good time to do this is when you feed them, as they will be out and easy to observe. Once they have finished eating, examine the tank to see if there is uneaten food remaining on the bottom. If you notice that there is often uneaten food left after ten minutes, cut back on the volume of food you give your fish at each feeding. Should you notice that uneaten food starts building up on the bottom of the tank, use a siphon to remove it. If the water level has dropped, top it off with treated or aged water as needed.

This is a good time to start an aquarium journal or log, if you haven't done so already. While there is no need to record everything, it is helpful to note anything out of the ordinary on your daily checks. That way you can catch trends that may be occurring. For instance, the temperature dropping by a degree isn't a huge deal, but if it drops a degree four days in a row, that's a tip off that something may be wrong with your heater. All of this can be done in literally a matter of minutes, so it's not a huge time investment.

- Count and observe the fish
- Visual equipment check
- Temperature check
- Remove uneaten food
- Top off water level
- Note concerns in a journal or logbook

Weekly/Bi-Weekly - I am a proponent of weekly partial water changes, while others prefer to do them every other week. As long as you are regularly performing partial water changes every couple of weeks, the exact frequency is not so critical. Use water that is treated, and if possible, aged. Replacement water should be close to the temperature of the aquarium. However, prior to performing the water change, perform the other weekly and every other week tasks first, leaving the partial water change as the last task.

The other tasks that should be performed every week or two is general cleaning of the tank. By performing light cleaning every couple of weeks, your tank will never get overly dirty. Wipe down the outside tank surfaces with a non-ammonia aquarium safe cleanser, or simply use a damp cloth. Gently shake plants, whether they are live or artificial, to dislodge debris. Scrape the inside glass to remove any algae, then take a break for ten or fifteen minutes and let everything settle a bit. When you come back, gently siphon the substrate to remove debris. Lastly perform a partial water change. Make notes in your log or journal of the maintenance you performed, and anything unusual going on in the tank.

- Wipe down outside surfaces
- Shake debris off plants
- Scrape inside glass
- Siphon substrate
- Partial water change
- Note maintenance in log

Monthly - Water testing should be performed monthly to ensure nothing unseen is brewing. I recommend testing the following parameters: pH, ammonia, nitrite and nitrate. If you have algae problems, you may also test for phosphates to see if that may be part of the root cause. Perform water tests first before water changes and any other maintenance. If you have live plants, inspect them and remove any dead leaves, and trim excess growth.

Next perform the weekly/biweekly cleaning tasks, followed by the partial water change. Save a bucket of the water removed from the tank to use for performing filter maintenance. If you use exhaustible media, such as activated carbon or zeolite, replace it. Using the water saved from the water change, rinse the mechanical media. If the mechanical media is very clogged, replace it. However, avoid replacing all the filter media at the same time. Instead retain part of the media to avoid losing too large a portion of the beneficial biological colonies. The next month you can replace the remaining filter media. Mechanical filter media (such as foam) generally only has to be replaced once or twice a year.

- Water tests
- Trim live plants as needed
- Perform weekly/biweekly tasks
- Change filter media
- Note maintenance and test results in log

Periodic - In addition to the scheduled maintenance tasks, there are a few things that should be done as needed. These include replacing the light bulbs once per year, regardless of whether they have burned out. Inspect the air pump tubing, and the filter tubing if you have a canister filter. Clean the canister filter intake using a filter brush. If you have live plants, fertilize them. - Replace light bulbs
- Inspect & clean tubing
- Clean filter intake
- Fertilize plants

Cleaning Equipment
Aquarium maintenance does not require a lot of equipment. However, it does help to have a few specialized tools on hand. The most important piece of equipment to have is a dedicated aquarium bucket, and make sure you do not use it for anything else. Having a second bucket is helpful, but not absolutely necessary. In addition to the bucket, a siphon, water conditioner, algae scrubber, filter brush, aquarium safe glass cleaner, soft cloth and some towels round out your cleaning materials. All of these items can be stored inside the aquarium bucket to make cleaning day quick and easy. Additionally, you'll need fresh filter media and if you have live plants, fertilizer and small scissors to trim the plants.
