I have a 26 bow aquarium with an ECCO filter and have been told to take out 1/4 of the water every 2 weeks and replace with new water. I have a normal amount of fish i the tank. It's not overcrowded. Is it necessary to change the water this often with a good filter like an ECCO?How often do you change the water in your aquarium?The filter is fine, and I will assume you do have a sensible number of fish.
But all the filter can do is convert ammonia into less harmfull nitrate. You still need to do water changes to remove the nitrate from the tank.
The exact amount depends on how many fish and how much they are eating etc. 25% every week or 2 is pretty normal. To work out the amount you NEED to do you should test your tank for nitrate buildup.
It might be 10% per week, it might be 50% per week, depends on how your tank is stocked.
IanHow often do you change the water in your aquarium?It depends. When I was treating my tank for ich I did a 25% water change just about everyday.
Normally it is best to do a 25% water change every other week or more if you have the time. When changing water use the gavel vacuum to get all the muck off the bottom.
It is always a good idea to change water. Look at it this way. would you want to be suck in small room with a bunch of other smelly people and not have any fresh air? A water change is like a breath of fresh air. It keeps them healthy and less stressed. How often do you change the water in your aquarium?What a filter basically does is convert ammonia to nitrite and nitrite to nitrate. Nitrate is the least dangerous of the 3 but it's still dangerous in high quantities. You need to change the water to get rid of the nitrate.
I do weekly 25% changes and a monthly 50% change.How often do you change the water in your aquarium?It doesn't matter how good your filter is. You must at least change 20% of your water each week. if you only change 10% of the water there is a chance that alot of waste will still be left over and will harm your fish. You should do a 80% water change every 3 months.How often do you change the water in your aquarium?Best to do 10-15% water change weekly, and a 30% water change getting in the gravel once a month.
Many people just do 30-40% monthly, and that's fine too as long as the tank isn't terribly over crowded.How often do you change the water in your aquarium?Even if the filter is good or not, there should be a 10-15% water change every week.How often do you change the water in your aquarium?Yep 25% every 2 weeks is great!
