How do,I change a saltwater fish tank into a freshwater fish tank(removing all the salt)?

Answer 1

use a mild dish soap and them scrub with plain water or vinegar wanter will work just make sure what ever you do rinse it wil hot water and rinse it good

Answer 2

Empty out the water (of course there should be no fish left in there), I find it easiest to use a siphon, like the ones for cleaning the tank, to empty the water, especially if it is a large tank.

A little bit of salt won't hurt freshwater fish, in fact it is even recommended to have a little in there to decrease the chances of disease and such. Refill the tank with tap water, making sure to use a product to remove the chemicals from it. I would then let it cycle for several days at least, with a running filter and no aquarium hood.

After it has started to cycle, make sure to do several water tests, including a salinity test. Most pet stores sell products to let you test the water, and some stores will even test it for you if you bring in some in a plastic bag or bottle. Make sure that everything is how it should be.

Then you can add a few fish at a time, depending on the size of the tank. Never add all of the fish at once, this will cause huge imbalances in the water and could kill them all within only a couple days. Only add a few, very hardy fish. Pick these based on the types of fish you are considering. Remember that goldfish can only be kept with goldfish, aggressive fish with other aggressive fish, etc. I would highly recommend buying a book.

Do not add an algae eater for at least a month, as it will probably starve to death otherwise.

Answer 3

You do know different fish right. Rinse it out. A little trace amount of salt is good for you freshwater fish. What type of filter do you have is it a skiltter or has a skimmer then you would have to get a different filter. There are brackish fish they live in salt and freshwater.

Answer 4

Well, if you're getting new fish, just empty the tank, wash it out well, and add in fresh water. Just don't put salt water fish in that tank since they'll die pretty quickly.

Answer 5

Dump it out & start over... you can use tap water treated with chlorine drops. However any salt water fish you had will not survive in fresh water.

Answer 6

dump it, put in fresh water, just make sure you check the salinity level before putting anything in, incase there is still a lot of salt in your substrate or rocks. (you are going to just have fresh water fish, right)

Answer 7

if you change it to fresh water it will kill all the salt water fish you may have in there.
but if you have no fish just empty it and refill it with treated tap water

Answer 8

dump it out and rinse it out and fill it up with clean tap water. dont kill your fish!
