🥇🐠 How to change Fish Tank Water

Today I will tell you how to change fish tank water.

If your aquarium has become dirty, if you see white spots on the glass walls of the aquarium, or if the strength of ammonia is too high in it then changing 50% of the volume of water in an aquarium is a must. This kind of maintenance should be done when any type of dirt appears in aquaria and at least once a week for full-fledged aquaria (aquariums with a capacity from 80 to 150 liters). But don’t do this procedure more than twice per month.

1. Remove all fish from tank:

Even if you are going to change only a small part of the water in your tank it is necessary to remove all fish from it beforehand. It is because if for some reason this water turns out to be unsuitable then there will not be any casualties. When changing more than half of the water in the aquarium, it is a good idea to drain all liquid and put just two or three fish back into an aquarium temporarily.

2. Fill up a bucket with water and add aquarium salt to it

First of all, you need to scoop out some of the old water from your aquarium and pour it into a bucket. Then add about half a teaspoonful of aquarium salt for one liter (one quart) of water. If your fish tank has a capacity that is bigger than 80 liters then you should use more salt: two teaspoons per 1 liter or 1/4 cup per 4 liters (1 gallon). Even if you are keeping marine fish with brackish water, their requirements will be satisfied by this amount.

3. Pour the mixture into the tank

This procedure shouldn’t take more than 20 minutes – during this time you have to change about 50% of the volume in an aquarium. Pour such a mixture first into the upper part of an aquarium and then pour it into the lower one. If you see that water from your bucket becomes clearer (after stirring) than water in your aquarium, then do not pour such mixture into the tank.

4. Repeat steps 1-3 until you have replaced half of the old water in the tank

If after pouring all mixtures together the proportion between them is still more than 50%, you should repeat all these measures once again before adding new water to your fish tank. In this case there also must be no living creatures in an aquarium because they can’t tolerate any amount of salt or chlorine entering their organism – even a small amount could kill a goldfish or some other tropical.

5. Clean out any algae or dirt that has built up around your rocks, plants, or decorations

If you see a considerable amount of brownish slime in the bottom of an aquarium then it is quite possible that this kind of microorganism is the cause of ammonia pollution. In this case it will be good to clean all décor items using a toothbrush and warm water mixed with soap. After that rinse each item thoroughly with water from a hose – remember that these things should not get into contact with tap water because they can’t tolerate chloramine which is widely used by municipal utilities to free chlorine from organic substances before delivering it into homes (it also kills bacteria).

6. Replace any decor items that are worn or damaged

If you have decided to change all the water in your aquarium it will be good to replace any décor items that are worn or damaged with new ones. For example, if old filter media is clogged and thus doesn’t allow water to pass through into an aquarium then some necessary substances may be lacking at the bottom of your tank.

If you follow these recommendations then there will not be any casualties after changing half of the water in your fish tank.

This kind of maintenance should be done when any type of dirt appears in aquaria and at least once a week for full-fledged aquaria (aquariums with a capacity from 80 to 150 liters). But don’t do this procedure more than 2-3 times a month because it is harmful for any aquarium plants. Also don’t change too much water in the tank at once – such procedure should last no more than one or two hours.

FAQ for How to change Fish Tank Water

1. How do I change the water in my fish tank without killing the fish?

It is very easy – just follow these short instructions. But remember that water of one aquarium should be completely replaced with fresh one not more than once every three weeks and to change no more than half of the volume during such procedure.

2. How often do you change the water in a fish tank?

As I have already said, any clean full-fledged aquarium should be cleaned at least once a week (when we are talking about 20 liters or less). If there is any dirt visible then it should be removed using gravel vacuum cleaner or other special equipment for cleaning aquaria.

To replace some of old water in an aquarium use a mixture consisting of two tablespoons of salt per 1 liter (1 quart) of water which means that you should add three to four tablespoons of salt into 10 liters (3.2 gallons) of water.

It is also necessary to change some old water in a tank if it appears that water in an aquarium has got cloudy – this happens when nitrites and/or ammonia levels are too high; Weekly changing procedure will help you keep nitrate as well as phosphate at undetectable levels, which in its turn will protect fish from developing diseases or getting poisoned by their own waste products.

3. Can I change all the water in my fish tank?

Yes, but not more often than every 3 weeks and no more than half of its volume during one procedure. 5-10 days after such replacement any excess algae finally dies off and thus ammonia and nitrite levels start going down.

4. How do you do a 25% water change?

Put an amount of salt the same as previously mentioned into 1 liter (quart) of water and pour all that solution into your aquarium, then take out up to 10 liters (3.2 gallons) of old water from it; add a mixture of warm fresh tap water and new salt solution; after that pour in another 10 liters (3.2 gallons) of this mixture – by doing so there will be only 5 liters (1 gallon) of old water left in your fish tank which means that you have successfully changed 25% of its volume with clean fresh one!

Good luck and happy fish keeping!
