Its been filtering for about a week. I have 2 fancy goldfish in it. I know your supposed to change some of the water every 1-2 weeks. How much should I take out? Does the water I put in have to be de-chlorinated?Need help with water change for my 20 gal. tank?you only need to do about 25 percent so 5 gals
and yes the new water needs to be de-chlorinated one way of doing this is to fill a 5 gallon buckit 24hrs before the water change it is better to age the water than to use chem. to do it you could also use several 1 gal containers
also this should be done at a rate of once or twice a monthNeed help with water change for my 20 gal. tank?You should only change about three gallons. Or right around 10%. We have a 27 gallon tank with sharks. Tank looks great.Need help with water change for my 20 gal. tank?Ok well, I'm not your typical follow the rules about water changing. I would change my water every 2 months, and by that I mean I would just vacuum up the poop in the gravel, gold fishies poop alot. And I would take the filter and just rinse it out. And every 6 months I would put in a new filter. My tank was nice and healthy for my fish. I had good levels with the bacteria and all the stuff you need for healthy water. I would also put salt in there to keep them healthy and if I noticed they would get like red spots on their fins I would buy this stuff called Melafix. Its awesome! And yes your water needs to be de-chlorinated!! Use something like 'tetra easy balance water' Or something that takes the chlorine and bad stuff out of tap water. Now from what I've learned is to keep the temps a steady temp and leave the water alone, unless your cleaning the gravel, you should be fine. My goldfish Max who I've had for over 8 years, is huge and healthy!Need help with water change for my 20 gal. tank?Okay. Here is the truth.
I do a partial water change EVERYDAY!
First off, 20 gallons is a bit snug for two fancy goldies. Since they require at least 30 gallons, I would reccomend my tank care routine.
People have this age old misconception that old water is good for your fish- this is FALSE!!! Sitting in poop and pee is unhealthy for anyone.
I take out up to 50% every day and replace it with declorinated room temp water. This keeps the goldies the happiest and healthiest- expecially if you have a small tank. Any current aquarium book will back me up on this.
The long and short of it is you should change as frequently as possible. Think of a fish in their natural habitat- they do not sit in their own waste. Changing the water will not harm the good bacteria either!
