White Foam (Bubbles, or Cloudy water) in Aquarium: Normal or Harmful?
You're always going to see some air bubbles in the water. It's the nature of the environment Air-driven filters can cause bubbles to develop, and air stones create cascades of small bubbles that help Move water around the tank.
Hanging filters can also cause bubbles to form.
Aquatic plants produce oxygen as they undergo photosynthesis. This forms small, jewel-like bubbles. This is called pearling and it is a sign of a healthy aquarium. Fast-growing plants will do this more easily than slow developers. If you don't notice pearling, your water may not have enough oxygen in it. If that's the case, the oxygen created by plants is absorbed by the water. Pearling is most likely to happen when the water is saturated with oxygen.
Tiny, clear bubbles that form on the leaves and stems of Aquatic plants are Carbon Dioxide (CO2) filled water capsules that occur during photosynthesis seasoned aquarists call this "pearling" and consider it to be a sign of excellent plant health. These bubbles are not harmful to fish.
Are the Bubbles in the Walls of a New Fish Tank dangerous?
When filling a new aquarium, a lot of agitation is created causing bubbles or a slight foam to form at the water's surface causing bubbles to form, but nothing to be alarmed about us these are completely natural.
What causes foamy bubbles in a fish tank?
Different factors, foamy bubbles are all tiny capsules of gas (oxygen or carbon dioxide) trapped in a film made of one of the following substances.
Agitated water
Bubbles often form when liquids are agitated; they are simply oxygen-filled water pockets. In an aquarium, this can happen in a couple of different scenarios.
When filling or topping off an aquarium, it's not unusual to agitate the water enough to cause at least some foam, which is normal and not harmful. To avoid bubbles when you add water to a tank, pour the new water slowly against a clean plate held at an angle so that the water runs down the plate and into the tank rather than splashing forcefully into the aquarium.
Protein
Protein foam is the result of organic waste. (Feces, dead fish, and uneaten food) forming an oxygen-trapping surface film that creates small air bubbles that stick together and form a smelly foam.
If protein foam is present, it is an indication that the aquarium needs a good cleaning. Make sure the filter is clean, and Remove any debris in the aquarium using a gravel vacuum.
How to get rid of Foam or Bubbles in a fish tank?
Make sure the filter is clean, and remove any debris in the aquarium using a gravel vacuum. Check for any dead fish that may have settled in a hidden corner, behind plants or rocks.
Cloudy water in Aquarium
After starting a new aquarium, it is not uncommon for the aquarium to become cloudy. This is due to beneficial, nitrogen-converting Bacteria colonizing to oxidize ammonia and nitrites. This bacteria bloom can also occur in an established aquarium if there is a sudden increase in nutrients.
Cloudy water can also be caused by the water being used. Tap water can contain items like heavy metals, nitrates, phosphates, and silicates. Ensure that you are utilizing a tap water conditioner as many conditioners will neutralize items like chlorine and chloramine, Ammonia, and heavy metals.
Add activated carbon media to the filter, whether loose or carbon pads. Adding activated carbon media or activated carbon pads to the filter will help clear the water and absorb nutrients that feed the bacteria bloom.
