In order to keep saltwater fish tanks healthy, clean and attractive, the owner must be committed to doing the work that’s required. Aquariums come in a variety of sizes and styles, and the simpler your setup, the easier it will be to maintain. Videos available on the Internet instruct their viewers on the proper cleaning and maintenance techniques for a saltwater tank. The main issues are algae growing on the glass and food particles and other debris that settles into the gravel or sand (the substrate) at the bottom of the tank. The aquarium’s filters must also be cleaned on a regular basis.
Assemble the needed item needed to complete the job, before starting. One requirement is a large pail or a smaller alternate temporary aquarium if the intent is to remove the fish. This is not required though unless the tank has gotten extremely dirty or contaminated. If removing the fish, it is recommended to take out up to 25% of the water in order to reduce the amount of contaminants. Use some of this water in your temporary container to put your fish in while you clean.
Turn off the heater and let it cool down before removing to avoid breakage because of a sudden temperature change. This only has to be taken out if it has become dirty and you want to clean it to keep it running efficiently. Cleaning the inside of the glass is done in a couple of different ways, such as with a sponge that has a long enough handle to do the job; Scrapers can be used if the algae is bad enough but be careful not to scratch the glass. Cleaning the debris/food residue, etc from the gravel/sand bottom (substrate) is done with a siphon. This can be manually or with a pump attached. These are purchased at the aquarium store and if you are a newby, ask for a demonstration for clarification of method and use. Once the siphon is activated, push the large tube into the grave/sand and wiggle it slightly. This stirs up the debris which will be sucked up through the siphon and into whatever container is being used to hold the dirty water. Be careful not to suck up any of the living inhabitants of the tank.
Continue moving the siphon around the bottom of the tank by lifting and re-inserting into various locations until the majority of gravel is cleaned. In smaller aquariums, move the rocks or decorations for better access to the gravel then replace to former location once that area is cleaned. This is a good time to do any rearranging that might be needed. Be careful not to disturb the roots of plants if at all possible.
After your aquarium is clean, the next task is to clean the filters. Remove the foam pads, clean them with de-chlorinated water, and then replace them. Removing as much as 25% of the water in the tank is a quick, effective way to reduce the amount of contaminants in your aquarium. When you add fresh water to your salt water aquarium, always use water that’s been de-chlorinated and is the same temperature as the water that’s already inside. You’ll also want to make sure the new water has the proper salt density. Mix the salt into the water thoroughly and use a tester to ensure the salt content is 1.025. Slowly add it to the aquarium so you don’t disturb the environment or the fish themselves.
Maintenance of salt water aquariums should only take 1 to 1 1/2 hrs every 1-2 weeks. Keep a close watch for sickness or sluggishness of the fish and separate any that show signs of sickness as soon as possible to keep the rest of the fish healthy. Basic foam brushing of the glass and filter will reduce the frequency that major cleaning is needed. If there is a lot of food on the bottom of the tank/aquarium then cut back on the amount of food given. Fish do not eat large quantities but prefer small amounts a bit more frequently. Larger and more diverse salt water aquariums such as “reef” aquariums require much more sophisticated filtration systems and serious cleaning of these may require hiring a professional. Regular maintenance is well worth the effort by keeping the inhabitants of the aquarium healthy, vibrant and a joy to watch.
