Maintaining your aquarium is something that has to be done on a regular basis. You do not need to break down the tank each time you have to clean it. Majority of the time you will only need to change 25% of the water, give the gravel a clean with the gravel vacuum and scrape some algae off the sides of the tank. It is recommended that you perform a water change every two weeks.

The items you will need to maintain a clean aquarium are:

  • Gravel vacuum
  • Two clean buckets (Ones that have never been used before and will be designated for the aquarium only)
  • Algae Scrub Pad
  • One to two towels


Create a maintenance schedule for your aquarium. You will need to clean your fish tank roughly every two weeks. If you’re able to clean it once a week, that's even better!







1. Turn off all electrical components connected to the fish tank. This is for your safety.

2. Use your aquarium safe algae scrubber to get off any algae from the walls of your tank, even if you cannot see anything there. Make sure you avoid getting gravel stuck in between your scrubber and the glass. This will cause the glass to scratch.

3. Using your gravel cleaner, remove 25% of the water into a bucket.

4. Check the filter media, if it requires cleaning, rinse it in some of the old tank water as the media will have heaps of beneficial bacteria. Avoid rinsing the media in tap water as it can kill off most or all of the beneficial bacteria.

5. Before adding replacement water, add in appropriate treatments to the existing water such as Bio Starter and Water Conditioner (refer to product labels on quantity required to put in your tank). Add in your water conditioner to each bucket of water before adding it to the tank. Check water parameters such as PH, temperature etc, are at an appropriate range for the aquarium.

6. Reconnect and turn on all electrical components

7. In 30 minutes, check to ensure all components are in working order






It is always important to closely monitor the water quality in your aquarium. With a new aquarium set up, it is important to test the water to ensure your fish stays healthy, and prevent ammonia and nitrites rising.

The following should be tested at least on a weekly basis:


Ammonia And Nitrite - In a new aquarium set up, ammonia and nitrite will elevate during the start-up cycle. In a mature aquarium, if the filters are not kept clean, the tank is too crowded or water is not changed regularly, this will cause ammonia and nitrite levels to elevate. The quickest way to reduce these elevated levels is to perform a quick water change. When you start-up your aquarium for the first time, these levels will quickly increase which can harm the health of your fish.


Nitrate – Nitrate levels will increase over time and can be removed by performing a water change. Although the nitrates are not as toxic as nitrite or ammonia, it needs to be monitored to prevent your fish from stressing.


pH – Fish cannot adapt to sudden changes in pH levels, and other water quality factors can cause stress and affect their health. Always remember that tap water will have dissolved gasses, so it’s best to let the water settle into the tank overnight before testing the pH. Plant and fish waste, topping of water and water evaporation will also contribute to the changes in the pH levels. When performing a pH test, it is best to do this test around the same time of day ensure consistent and accurate results.


Phosphate – A major source of phosphate is fish food, particularly if the fish are being overfed or low quality food is used. Phosphate serves as a nutrient for algae. Ensure you clean the inside walls of your tank when performing water change at least once every 3 to 4 weeks as a precaution. If you have excessive algae forming, there are filtering materials you can use to help remove phosphate.



Regular testing and maintenance of water parameters is important for the health of fish, plants and coral. Aqua One Quick Drop Test Kits make it easy to monitor a range of water parameters helping to maintain a healthy aquarium.

Keeping track of your aquariums parameters is important to maintaining a successful tank. Track your records with a log book to best manage your findings.

pH is the measure of alkalinity and acidity within a liquid. pH measured on a scale from 0 – 14 with 7 being neutral, 0-6.9 is acid, 7.1 – 14 is alkaline. Each change in one pH unit reflects a tenfold increase or decrease in the pH value e.g. pH 10 is ten times more alkaline than pH 9 and one hundred times more than pH 8. It is therefore extremely important to make adjustments to pH slowly.

Clarify is a polymer based flocculent that binds fine particles in aquarium water so that they can be more readily removed by mechanical filtration and gravel syphoning. By removing these fine particles water will become clearer and odours will be reduced.
