What maintenance should I do on my aquarium?
The varies between all set ups, but as a rough guide you should do the following:Daily✔ Check fish for signs of disease✔ Check water temperature✔ Check filter is working correctly Weekly✔ Remove 10-15% of water and replace with de-chlorinated water - try using King British De-Chlorinator✔ Test water conditions are suitable for the fish you keep (different species require different conditions) - Try adding King British Filter Aid + to help maintain good...
How long should I leave my aquarium lights on for?
For a planted tank 8-10 hours a day will be more than sufficient. Lights should never be on for 24 hours a day - the fish and plants will need their rest and without it may become stressed, possibly resulting in poor health and even death. What about direct sunlight? Be sure that your aquariums are kept out of direct sunlight as this will only promote the growth of algae in the aquarium.
Does my aquarium need gravel or substrate?
Substrate is recommended for various reasons, primarily because it provides biological filtration, allowing for beneficial bacteria to grow. Without it, beneficial bacteria might not grow in sufficient quantities to keep the water safe for your fish. Gravel will also provide a much more natural habitat for your fish, helping to keep stress levels down. It also provides somewhere for live plants to be bedded.
What is a biological filter?
The biochemical function of the aquarium filter is to remove harmful substances from the water by biochemical reaction. This means that bacteria within the filter can chemically alter a substance (for example, ammonia) to turn it into something else. Nitrifying bacteria are responsible for removing the dangerous ammonia and nitrite that are produced by fish as a waste product. They do this by changing the chemical composition of these toxic substances, resulting...
Why does my aquarium water have a pale yellow tinge to it?
This could be caused by a number of factors, however it is usually caused by leaching from aquarium gravel or bogwood in the aquarium. Make sure you wash any gravel and bogwood thoroughly before putting them into the water. It can also be a sign of over feeding, so check you are not feeding too much. Always remove any uneaten food from the water, and maintain your aquarium regularly.
Why are nitrite levels slowly creeping up in my new tank set up?
What you are experiencing is very common. Your aquarium is still not 'mature', which means the filtration system has yet to establish a level of beneficial bacteria that are capable of consuming the nitrite in your tank. There are no 'set in stone' rules on how long it will take your aquarium to mature as there are so many factors that affect it. You can help the process by doing the following ✔ Manually increasing the number of bacteria in the filter using a...

How often should I change my aquarium water?Most aquariums should be cleaned every 2 weeks on average. It is easier to combine cleaning and water changes by using a gravel siphon, as this also removes any dirt and waste from the bottom of the tank.
When can I add new fish to my tank?
If you are introducing new fish to a matured aquarium, then there shouldn’t be a problem. However, you should monitor the ammonia and nitrite level for the few days following introduction as a precaution. Also, you should quarantine any new fish for at least 4 days in a separate tank before adding to your main tank. This will help to prevent spreading any diseases.
It is advisable to run a new tank with water only for at least 1 to 2 weeks before adding fish, to allow the filter to build up some beneficial bacteria. It helps to add King British Filter Aid + during this period to help the filter to mature. Fish produce ammonia through respiration, and release it into the water through their urine and across the gills. In a matured aquarium, the filter can remove the ammonia quickly before it causes any problems. However, in a new, un-matured aquarium the ammonia will linger and may build up and cause problems. If fish are added straight away to a new tank, then the ammonia they produce can poison them and they may die. Also, once you do start adding fish, they should be added slowly and gradually, not all at once. Spread it out over of a period of weeks by adding two or three fish at a time, to allow the filter to adjust to the larger load of ammonia and nitrite.
