How often do i need to change the water in a NEW 6ltr tank with 2 goldies?

My children were bought 2 little goldfish in a teeny 6ltr (1.5 gal) tank last week with under gravel filter - we added an air pump with air stone to make things more comfortable for the 2 goldfish - i have been changing about 25 - 30 percent of the water every day (adding dechlorinator to the new water) if is becoming a bit of a pain - i dont want the fish to die, but wonder when it will be safe to cut down on the water changes?



any advice on new tank set up care welcome!!!



many thanks in advance!!!



Emi and the twins fishHow often do i need to change the water in a NEW 6ltr tank with 2 goldies?Hi Emi. I also have twins with small tanks (each got their own). They keep a betta in the tank with the underground filter and air pump. We completely do a 100% water change once a week and there is only 1 little low bioload fish in each tank.

Unfortunately, goldfish are not as easy to take care of. A goldfish can live for 20 yrs and gets up to 8%26quot; when taken care of properly. They require 10 gallons per goldfish and extra filtration because of the high output of ammonia (through decaying food as they are messy eaters, urine, feces and simply through exhalation of oxygen through their gills!). In a 20 gallon tank with 2 goldfish, a filter meant for a 30 gallon tank is recommended, with weekly water changes of about 25 - 30%. While it is somewhat true that fish will only grow to their tank size (called stunting), it causes internal organ damage and early death. A water testing kit that includes a test for ammonia, nitrite and nitrate is necessary. Ammonia is toxic and burns the fins, skin, eyes and worst of all..the gills. The next step in a cycled tank after the ammonia spike is nitrite. Nitrite lasts a few weeks and is also toxic. It creates long term problems as the fish damage their ability to do an oxygen exchange and they die of asphyxiation. The third step in cycling is the creation of nitrate. Nitrate should be kept at 20 ppm in a cycled tank and will eat up the other bacteria as quickly as they form as long as you do the weekly water changes.

Because of this, my 6 yr old twin boys were only allowed to get bettas. Hope this helps.How often do i need to change the water in a NEW 6ltr tank with 2 goldies?I think you only need to clean out the tank about once every 2 weeks because the filters and pumps will clean most of the bad stuff in the water. I have 2 fish in a 7ltr tank and only clean it out once every 2 weeks.

In that small you want to do a water change like every dayHow often do i need to change the water in a NEW 6ltr tank with 2 goldies?Considering the tank is so small, I檇 say at least three times a week.

My goldfish are in 20Litre tank, and I have to do a 50% water change every 4-5 days to keep the ammonia levels down.



Considering you have an under gravel filter, I檇 suggest buying a test kit for Ammonia, Nitrate, and Nitrite so you can keep an eye on how the filters working.How often do i need to change the water in a NEW 6ltr tank with 2 goldies?You have a filter and a air pumb, so u can change 30% every week, do not overfeed the fish, bcuze the more u feed the more the water will become dirty.How often do i need to change the water in a NEW 6ltr tank with 2 goldies?I suggest getting a water testing kit and using it to determine how long to go between water changes. Personally I let the nitrates get to 45ppm and do a 20% change -- in my 10 gallon tank with a good size pink gourami, a small algae eater and a male Betta, this is usually around six weeks.



Since you mentioned advice on new tank setup and care, I'll assume this is a new tank. If it is, then you will go through a break in cycle which can last as long as six weeks.
