How to Maintain a Reef Aquarium

If you have a reef aquarium, maintain it by adding filtered water when the level is low in the tank.  Also, clean water once a month by replacing 1/4 to 1/3 of tank water.  Check your filter to make sure it is running properly as well, and purchase a water testing kit to make sure chemicals are at a proper level.

• Place soft corals near your filter for the best growth.  This keeps coral healthy because they receive a good flow of oxygen.  Harder coral needs to be placed high up in the tank, near lighting.  This lighting is necessary for hard coral health.  Keep lights on all the time in your tank to keep coral growing strong.


• Add filtered water to your tank when it becomes low.  Water must be de-chlorinated for proper maintenance of your reef.  Check on water levels often and add water when needed.  Use room temperature water because drastic temperature changes are harmful to fish and plants.


• Clean water at least once a month to keep it clean.  Remove 1/4 to 1/3 of dirty water.  Add fresh filtered water to replace the water you removed.  Clean your tank more frequently if you notice that it becomes dirty often.


• Check your filtration system regularly to make sure it is working properly.  Change pads when they become dirty and make sure the system is connected properly.  If filtration is not working correctly, replace it immediately.  This is important because good filtration is necessary for the health of your reef.


• Test your water at least once a month to make sure chemical levels are maintained. This can be done with a testing kit purchased from your local aquarium supply store. Test pH, calcium, nitrate, and copper.  If levels are too high, or too low add chemicals to your aquarium.  Purchase chemicals that are appropriate for your tank for safe use.
