Why does my swimming pool have bubbles?

Blowing bubbles back through the pool returns? Air leak on suction side of pump. Bubbles from foaming? Too much algaecide!

Generaly what appear to be air bubble is actually vaporized water molecules. \nAt the boiling point high energy molecules of water convert to gasious state and thus they look in the form of bubble. As the water vapours are transparent like air we assume the bubbles to be made of air but actually the bubbles are filled with water vapours.\n\nHowever, in the very early stage of heating water the dissolved air scapes from water. Usually this escaping air does not form bubbles but sometimes tiny bubbles are also formed. Nevertheless, this happens much before actual boiling.

The weight of water does not change when it freezes, so the bubble would not fall to the ground due to its weight--it would continue to drift and float. However, bubbles are held together due to the surface tension of water and the way that a surficant (such as soap) stabilizes the bubble, so a frozen bubble may not be stable.

First of all, make sure that your test kit's reagents are still good. If they've ever frozen or are over a year old, they're no good.\n If your reagents are good, then what about your chlorinator. You shouldn't need to use a floatie with a chlorinator at the equipment. Also, you ought to be putting more than 2 tabs in that chlorinator. The usual method is to half fill it and adjust the flow to it as needed on the dial. Perhaps the chlorinator is plugged. They do get mucked up.\n Are you testing for Total alkalinity? If not, you should be. It's more important than PH or Cl as it is what governs whether everything else works, water chemistry wise.\n Have you taken your water in to a pool shop to have the cyanuric acid (stabilizer) levels checked? Too low a stabilizer level and the cl gets zapped out by ultra violet in no time. To high a level is not good either and may require a partial pool dump and fill.Stabilizer levels affect Cl levels.\n\n Yes, it could be phosphates. Is your pool green or does it flip to green in hours? Usually caused by not having proper sanitizer levels or bad water chemistry ( that TA thing again)\n\n Are you shocking once a week.?Yep, you're supposed to. Shock ing over chlorinates the pool briefly, to get rid of what the chlorine pucks couldn't deal with during the week. No shock, no chlorine reserves left.\n There are many things unique to your back yard that may be doing this as well. Are there a lot of organics constantly falling in the pool? What's the bather load, is yours the only pool in town?

Could be a case of swimmers ear or a fungal infection of some type.  See your doctor to make sure and get treatment.  I know how bothersome this is.

It sounds as if your skin is having a reaction to the chlorine. The balance in the pool may be off as well. Do you shower as soon as you get out of the pool? If allowed to dry Chlorine can irriate the skin..

The water from the bottom is being transformed from liquid to gas and the gas bubbles to the top.  Kinda like when you're in the bathtub and fart.

air bubbles look like little circles that are just floating around in the specimen area or space sometimes the air bubbles have air pockets in them to

Air, being in solution, is lost all the time at the top of the glass of water and nobody is aware of it.  Air particles by the same effect tend to break away from the water body at the glass sides and bottom.  Contrary to the top, there is a glass barrier, and air particles simply cluster together as small bubbles.  These bubbles of course become bigger with time and some become big enough to break away and float up to the surface.  This effect is much more apparent if you heat the water lightly as the air in solution expands.

By mistake in a pool but it probably wasn't too much....\n\nWhy? Are you sick?\n\n:)

It might scratch the pool liner.

my guess is that the burning is from irritation.  next time you might wanna have more water in the pool before you go swimming.

if its not my swimming pool

Human ears are adapted to hearing via air not via water.  Also there are a couple transition boundaries that muffle and distort the sound.  The first being the surface of the water in the pool.  The second being the air bubble that is still in your outer ear.\n\nIf you remove this air bubble by inverting your head and shaking it side to side you can actually hear "better".  But the speakers voice will be very distorted from passing through the first transition boundary.\n\nMake sure that you exercise proper ear care after your swim to ensure that water does not stay in your outer ear and cause an infection.

The chemicals are probably different from the other pools you have been in and you are sensitive to them.

have your water tested, it could be a virus, a bacterium, or even lead...have it tested ASAP

Everyone says that The surface tension causes the bubble to be spherical. But how? and Why? \n\nLets explain surface tension first- \nIn an air-water interface, the molecules that are close to the surface are attracted by fewer molecules of the liquid than the ones that are NOT close to the surface. The former thus, has less attractive potential energy than the latter, right?\n\nNow, for any matter (solid or liquid), attractive potential energy results in stability & repulsive energy results in instablity (common sense). \n\nSo, it is energetically unfavourable to have a surface for a liquid (or solid) as it results in loss of attractive potential energy.\n\nNow, for that reason, a bubble wants to have the lowest possible surface area to remain stable. Now, using some high level mathematics, someone found out that a sphere has the lowest possible surface area for a given volume. (it is better than a cube atleast).\n\nHence why we can see that the water bubbles and drops tend to be spherical. Due to the effect of gravity, although the drops appear oval in shape but, in the absense of gravity, all the liguid-air surfaces tend to be spherical.\n\nI hope it helped.\nHave a nice day!
