Extremely required information: size of tank!
1 gallon = every 3 days
5 gallon = every 5-7 days
10 gallon = probably a week or two.
It does depend on your fish. What you should do, is test the ammonia every day. When ammonia shows up, mark how long it took, and that is how many days the tank can go without a complete change of water.
Cycled tanks are a different matter. They only need occasional partial changes.
Once a week.
Never. You should change the water a few times a week if the bowl is not filtered, but do't completely clean the blwl or wyou will destroy the benifical bacteria that converts ammonia and nitrite to nitrate and o2
Tap water is the best water for betta fish! There is no need to go out and buy expensive betta fish water...it's no different then tap! If you want to be sure that the tap water is safe for your betta, put in some sort of conditioner for the water.
Beta particles are often used in smoke detectors.
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
False
When you first change the water in your aquarium , there is lots and lots of waste flowing around in the water from the gravel in the bottom of the tank. it seems that your beta is just getting oxygen from the top of the water. hope this helps
No. Beta emission does not change the mass of the atom.
To get Yahoo Mail Beta, just switch your content preference to Germany, France or UK. Then you will be asked if you want to join the beta when you log into your Yahoo Mail. Say yes, and join the beta. Then from the options menu, change your content preference what it was before. Then go to Yahoo Mail again. You should see Yahoo Beta. If you don't see it, go to options and click "Try Beta" button. That's all.
When a beta particle is emitted from a nucleus via Beta- decay, the mass number stays the same, and the atomic number goes up one, because one neutron is changed into one proton by Beta- decay.In Beta+ decay, the opposite is true. A proton is converted into a neutron, again keeping the mass number the same, but in this case reducing the atomic number by one.The ending result is different, however. In Beta-, the beta particle is an electron, while in Beta+, the beta particle is a positron.
the rate of reaction will change
Possibly bad water conditions or shock from a badly performed water change or maybe it has been netted and handled roughly.
