How often do you have to change water in a small tank?

i got this cheap little... well i wouldn't even call it a tank.

but it has an air pump type thing that bubbles the water up

and i have two fish in it.

how often should i change the water, and do i need to get anything to put in the new water?How often do you have to change water in a small tank?If your tank is under 2 gallons, you should NOT have 2 fish in it, unless they are tetras (you can have 2 per gallon in this case, but really need to have 6... so not a good choice :-P)



But, anyways. It depends on how much waste your fish makes. Goldfish need to have about 20 gallons of water each or else they will need a water change daily.



The air pump that makes bubbles- its a bubbler. It circulates the water and creates a current. I prefer a filter, but this at least circulates the water.



you should change the water... depends actually on the size of tank and type of fish. The smaller the tank the smaller, but more frequent water changes they need.



If the tank is 2 gallons or smaller, go for a 25% water change 2 times a week (small tanks are a pain in the neck to take care of, i have one)

The only real way to know is to get a liquid water test kit. do NOT get the strips as they are not accurate.

They check the water for ammonia (deadly, and is created by the fishes waste), the Chlorine, and the Chlorimine (also very deadly)

your tank is not cycled, so untill it cycles itself, you really need to watch the tank levels.



If you are not able to get one of these kits, as they are about $25, just do the %25 water changes maybe on a Sunday and wednesday/thursday.



oh and i forgot to add, you will need to get a water conditioner (aprox $2-4). It removes the deadly chlorine and chlorimine in the tap water. Try to add it to the water before putting it in the tank. I use a gallon jug, fill up with the water, add the conditioner and let it sit for about 1/2 hour. as soon as water is room temp, you are good to go. If you don't use one, the chlorine from the water will burn the gills of your fish, and has a high chance of killing.

Good luck.How often do you have to change water in a small tank?Hi

A small tank, like a 1 gallon ?

Ok, professionals advise changing the water that with holds a filter media to once a week. No filter----every two days. Say every saturday.

Now you need a heater for certain fish, and you require water conditioner, to remove any chlorine, metals that come through the pipes, or spring water.

Maintain a clean filter, when it gets orange, change the filter floss.

Don't forget to airate the waterHow often do you have to change water in a small tank?it depends on the fish you have, if you have goldfish, then you should change 25% of the water every 1-2 days, if you have tropical, such as guppies, platys, tetra etc.......

then you should change 25% every 3-4 days, because goldfish produce more waste then tropical you need to change it more often. Fish usually die if you change alot or all of their water. you should always use dechlorinator to make the water safer, I think i have the same small air pump thing as you do. You might need a heater if you have tropical.



Hope i helped :D

Goodluck!How often do you have to change water in a small tank?Knowing the gallons would help us help you. But if it's really small, then it also depends on what you have in it. Sounds like you have a air stone, but not a filter? if you have goldfish, then every other day as they produce a large amount of wast. Do only partial water changes. have some treated/aged water on hand at all times. If they are tropicals you might get away with every 5 days. But i really need to know how many gallons, what type of fish?How often do you have to change water in a small tank?how many gal does it take. 2 fish depending on type need 10-20gal. you can get a water filter to help til you can get a bigger tank.you might have to change the water everyday to everyother dayHow often do you have to change water in a small tank?Well at least once a week but if you notice that once a week is not helping then clean it more times. No you don't just take out about 80%of the water and then refill it with new water.How often do you have to change water in a small tank?Once a week. Take out 25% of the water and replace it. Remember if you're using tap water, use water conditioner!How often do you have to change water in a small tank?25% of the water monthly.
