How do I add more water to my already existing fish tank?

Question

I already have my fish tank set up and my fish in it - but about 2 inches of the water has evaporated. Can I just add more water...

Answer 1

I'm assuming its fresh water not saltwater or brackish. In any event you can add more dechlorinated water. Best is to match the temperature and pH first.

Keep in mind that only pure water evaporates. Each time you add water the hardness will increase in your tank and ultimately pH by extension unless there are other factors such as decaying plants/waste etc. which will lower pH.

Safest water to add and NOT increase hardness is distliled/RO/DI water. But that has to be added slowly because it is unbuffered and carries a very low pH.

If you are not a perfectionist then just dechlorinate some water and match the temperature as best you can and pour it in.

A good idea is not just replacing water, but actually removing water each week and refilling. This is a water change and will do wonders for everything in your tank.

Good luck.

If this is a freshwater aquarium, I can answer. Yes, to add water, make sure you use something like Amquel to treat it before adding. This type of agent will not only remove Chlorine, but also Chloramine (ammonia bonded to chlorine to improve antibacterial action in your city's water supply. Typical dechlorinators won't break the chemical bond.). Remember that dissolved wastes will be more concentrated in the existing water, and so from time to time, you will need to do a partial replacement, and also find a way to remove solid wastes which you will see at the bottom of the tank.

If you have freshwater, then ya you can just add, and then check ph and other level and adjust as necessary. But if you have saltwater, you have to use a salinity meter to determine your current salinity, then mix up some additional water using regular water and mixing with salt (the kind from the aquarium supply store, not table salt!) until your additional water has basically the same salinity as the existing water. Then you can put in the additional water, but be sure to add some Amquel after you add the water. Finally, check the other chemical levels and treat if necessary to reach appropriate levels.

Depends on your water. Did you have to put a chlorinate in it when you set it up? If so, you will need to fix up water a gallon at a time and add to it slowly to keep from stirring up the tank. If you have well water, you should be able to add it directly, but slowly. It is best to save some washed out milk jugs to keep water in so it will be ready to add when needed. When water has sat for 24 hours, it is usually safe to add with no chemicals needed. Former tank owner.

Answer 5

Yes let the water sit out in a seperate container for about 3 hours to get to room temperature, you dont want to change the tempurature of the water too fast.....I always have an old water bottle filled with tap water to refresh and add to the tank.

Answer 6

in the beginning it truly is something which you have already executed yet while no longer you will possibly desire to make specific that your fish (new, and previous) are interior the comparable group. as an occasion if the fish that are already interior the tank are aggressive it truly is ideal that the fish quickly to connect them are aggressive besides and enormously plenty the only different issues you will possibly desire to do are to waft the bag the hot fish are in into your tank for about 15-20 minutes then as quickly as the time has handed do no longer unload the water from the bag, scoop the fish out. i might recommend which you positioned the hot fish interior the tank after the previous fish have already been fed giving the hot fish time to get use to it truly is new abode till now a feeding.

Answer 7

The new water must have de-chlorinator added to it...you can't use straight tap water. Just add the drops of the dechlorinator to the new water in a clean (soap and chemical free) bucket if it is small amounts of water to a small tank.

Answer 8

My sister had this awesome thing called a python, it was like a garden hose kind of. You could hook it up to the tap, you just have to be careful about the chlorine and salt and other chemical levels in the tank.

Answer 9

Yep, just poor in more water. I guess it would depend on if your tank is for tropical fish, or salt water fish...

Answer 10

Yes.

I have a couple of empty gallons I fill up with tap water, I put chlorine remover shake/mix it up a pour it in.
