You have ammonia in your tap water. What level of ammonia do you have after your water change and what level of ammonia do you have after 3 or 4 days before you do the next water change?
My Bettas 6.5 inch aquarium. every 3 or 4 days I have to do water change, is every 3 or 4 days normal to clean a tank this size? I have high amounts of Ammonia. Thanks.
6.5 INCH?????? I think you mean Gallon.
If you are getting that much ammonia after only 3-4 days after a water change, you are probably overfeeding. Cut back on the food as some of it is decaying in the tank. Since there is only the one fish in the tank, it's not from overcrowding, it's not from being uncycled and you claim the ammonia level is 0 after the water change so it has to be the food or the filter needs to be rinsed more frequently which is usually because of over feeding.
Just for giggles tho, check the ammonia level in your tap water.
Yes! I meant to say gallon I am only feeding 3 small pellets, that is not over feeding, as far as I know. I feed 3 small pellets every day. i tested my water from the tap water and it shows 0 ammonia. I tested with Api liquid test kit.
Consider that a Betta's stomach is about the size of it's eyeball so even tho they are small pellets, they may still be too much. Try cutting back to 1-2 pellets every other day and see if you are still getting such a rapid ammonia level.
What precisely is the ammonia reading?
