The most important part of any aquatic ecosystem- now matter how small- is the bacteria. The bacteria that live in your bettas tank convert the waste he produces into a harmless substance.
This bacteria takes time to accumulate. If you change all the water you are removing all of the healthy bacteria and your water will actually become dirty more quickly. You get in the cycle of changing the water every week. This is not good for the fish. There are more things to worry about besides chlorine and temperature. The extreme difference in Ph and oxygen will be more than enough to stress out a fish.
By removing only 25% of the water at a time you leave the biological filter intact. If you have your fish in a bowl- not very nice- then you may have to do this daily. It should be very easy tough. Take a scoop of water out and replace it with fresh. You can add a drop of your chemicals if you like.
Occasionally you will want to siphon, or at least, stir up the gravel to remove any large debris. You should never remove more than 1/3 of the water at a time. If you do their may not be enough bacteria to destroy the bio-load your fish produces. When this happens the ammonia in the water burns the fish's' eyes and gills.
People who change the water all the time essentially have fish living in septic conditions. The chemicals burn them and then as soon as bacteria begins to grow and level out water parameters- they dump out all the healthy water and replace it with sterile bottled crap. Water that looks clean isn't necessarily healthy.How often to change water?
I hope your betta is in a tank, and not in one of those tiny cups, which are horribly cruel. Yes, they CAN live that way, but it doesn't mean they HAVE to.
To change a fish tank's water, just take out about 25% of it (I use a siphon hose to vaccuum the bottom so the waste gets sucked up) every month or so, depending on the size of your tank and how many fish and what type of fish you have.How often to change water?
Hi
I don't understand it either.But I have two Betta and I change my Betta's water every week and make sure that you do it on the same day every week.Like me I clean my Betta water every Sunday and they have lived 3 months.I have a male and female.I have alot of other fish to.So if you need help with any other help to do with any fish please let me know I can help you.My email is garlandangel101@yahoo.com please do not hesitate to ask.How often to change water?
use spring water take 75% of the water out replace with 75% waterHow often to change water?
I would only when the water turns yellow or greenHow often to change water?
How often you change the water depends on the size of your tank/bowl, and on the lack/existence of a filtration system. Anything less than a quart, I'd change the water 25% (i.e., 25% of the volume of the water -- you can eyeball it -- siphon out 1/4 of the water, and make sure to suck out the debris on the bottom) EVERYDAY or at least EVERY OTHER DAY. Of course, use dechlorinated water that is of the same temperature as the old water. If you have a gallon of water in the tank, I would change 25% of the water at least once a week. If you have a filtration system (I personally like Marineland's Eclipse System Three), I still would do 25% water changes weekly for the first month and a half until a colony of beneficial bacteria gets established to convert the ammonia (very toxic -- ammonia comes from fish pee and poo and uneaten food) into nitrItes (still toxic) and the nitrItes into less harmful nitrAtes. After that, a biweekly 20% water change is sufficient (This is to dilute the nitrAtes). You can't have a tank that is too clean!
Don't wait until the water turns yellow or green! Ammonia is invisible to the eye but highly toxic to your fish.
