Aquarium Salt Water – When’s The Time To Change It?

by The Aquarium Lady

Aquarium salt water in any tropical fish tank will need to be changed at some point. Although you may have a good filtration system which is able to remove most of the waste which builds up in the aquarium salt water, the filters on these are not so effective that they can remove it all.

If waste material (food and other debris) is allowed to accumulate it can actually cause the water to turn cloudy or yellow and increase the production of algae in the aquarium salt water also. These buildups can then lead to problems in relation to the growth of the fish and other marine life (coral and invertebrates) in the tank and could result in them becoming ill. Therefore when it comes to changing aquarium salt water you shouldn’t be asking yourself should I be changing the water, but when should I be changing it?

When Is It The Right Time To Change The Aquarium Salt Water?

Ideally one should not be leaving the tank water along until such time (may in a few months time) before they decide to change the aquarium salt water so that they are able to provide a cleaner environment for those that are living in it. Often people will remove all the saltwater fish, invertebrates and reef items from the tank so that they are able to remove all the water currently in it and then replace with freshwater. The problem with doing this is it could actually cause more harm to the marine life living in the aquarium than it will do them good.

Rather the best way to do it when changing aquarium salt water is to remove about 1/3 of the total amount in the tank on a regular basis and keep the saltwater fish, invertebrates and reef coral in it. Then after removing 1/3 of the total aquarium salt water you should then replace this with the same amount.

Steps To Take When Changing The Aquarium Salt Water In Your Tank

1. Firstly, you need to make sure that you turn off all the heating pumps and filters that run in your aquarium and then unplug them. If left running the chances of them overheating because of there not being enough aquarium salt water in the tank for them is greatly increased. Plus if left on then when you add more freshwater to the aquarium the chances of the heater causing the tank glass to crack is greatly increased. What price is it going to cost you when you have to replace the entire tank?

2. The next thing you need to do is get rid of any waste and algae build up on the insides of the aquariums glass using an aquarium scraper or scrubber. When using these kinds of aquarium salt water accessories you need to use them very gently and slowly so that you don’t disturb the marine life in the tank which may cause them to become panicked or stressed.

3. After scrapping the insides of the tank glass you now need to remove any plants you have in the aquarium salt water and from these remove any parts which are dead or dying. Then once you have removed the plants you can spend time stirring up the gravel to help bring any waste deposits to the surface, but do so carefully as some species of salt water fish like to bury inside it. If you can put a large amount of the gravel towards the back of the tank and then leave the rest where it is so that the waste deposits can then settle on top of it.

4. Now that the gravel and water has settled it is time for you to remove some of the old aquarium salt water so that you are able to replace it with fresh using a specialist piece of siphon equipment. Don’t forget you should only ever remove around one third of all the water in the tank each time you are going to be changing the water in it. These specialist aquarium siphon products not only make it easier for you to get rid of the old aquarium salt water but also help to get rid of more the waste that has built up since you last changed it.

5. You are now ready to replace the aquarium salt water which you have removed, but don’t use freshwater rather replace with water to which you have added a specials salt mix product or which has been left to stand for several days. This will ensure that the chemical composition is almost in balance with the water you currently have in the aquarium. Please note that at no stage should you use ordinary sea salt for your aquarium but only ever a specialist aquarium salt. Also it is vital that the aquarium salt water being added to the tank is close to the temperature (no less than 2 degrees Fahrenheit difference) between it and the water already in the tank. Plus it is a good idea to test the aquarium salt water after the new has been added to make sure that you don’t need to add any more aquarium salt into it to keep your fish and marine life happy.

The last thing that you need to do before you actually plug the filtration system and heater back in and turn them on after changing the aquarium salt water is clean the cover and the glass on the outside.
