The pressure increasing indicates that something is blocking the filter.

Phosfree is said to remove phosphates from pool water which is then cleaned out with the regular filter clean or backwash. reducing phosphates in water reduces the posibility of algae in pools.

Just let your filter get dirty and the pressure will increase. To increase the flow rate from the norm a bigger pump will be required.

Salt water is more dense than fresh water. The added density adds pressure, so the pressure will be greater at the same depth in salt water. This is also the cause of the increase of buoyancy in saltwater.

It is not possible to have pressure in a pool

A clogged filter? The pressure AT THE GAUGE will drop after the pool is backwashed and also during vacumning. As the filter becomes clogged the pressure AT THE GAUGE will increase. The opposite effect occurs at the inlet eyeball.

The source of your water that you add into the pool will increase the PH level. Also the chemicals you might be using will also do the same thing. Any chemical that may have Sodium in it will increase the level.

A pool with a sand filter or for that mater any filter is set up to push water through the fitter to be filtered. when the filter is clean the gauge in front of the filter Will have a low pressure reading. As the filter gets loaded with more of the dust and dirt that comes from the pools water it becomes harder for the water to pass through the filter and the pressure on the gauge goes up when the pressure get high on the gauge it is time to backwash the sand filter or to clean the cartridge filter. When the pressure on the gauge is high the suction from the pool is low. When the suction from the pool is low even when the pressure on the gauge is low there may be a problem with the pump, or a blockage between the pump and the pool, To increase the amount of pressure on a clean filter the only thing that can be done is to enlarge the pump.

depends on size of pool. the bigger the pool, the more area that is covered by water. by adding more water you increase the pressure that will be administered to your swimming pool. make sense? doesn't to me, but its the truth. Swimming pools do not have PSI per say.

Have you actually added liquid chlorine to the pool?

Lanthalum based compounds have been very effective in removing phosphates from Pool Water. A compnay called LO CHLOR has a product called STARVER which has good reviews. Natural Chemistry also makes products for removing phosphates called PhosFree.

A standard bubble pool cover and increase your pool water temperature by up to 10 degrees Fahrenheit.

Clean the filter, enlarge the filter, enlarge the pipes coming from and or to the filter, enlarge the pool pump, If you have a cartrige filter put another one in paralel next to it.

Heating a pool will increase the rate of evaporation from that pool.

Most commonly Phsphate removing chemicals are Lanthanum Chloride which kills any Phosphates in the water. This does take about 3 days of normal filtration to do its job.

UNLESS YOU DIRECTLY INJEST the salt, it should have no effect on your blood pressure. ALSO, if you swim in a very warm pool or sit in a hot sauna or steam room, the heat dialtes your blood vessels and actually temporarily LOWERS your blood pressure.

No specified pressure at the "return" fittings at pool side. You do not measure pressure at these points.

It is not possible to have a pressure level on your swimming pool! However the pressure on the filter gage could run anywhere from 5# to 35#

Pool temperatures can be increased by installing a pool heater. They can also be raised by using a solar blanket.

Pressure inside Earth increases much like pressure in the swimming pool increases.

A Hydrostatic valve is basically a plug that stop water coming down out of the pool, but when the water pressure under the pool gets higher then the pressure in the pool it will let water into the pool from underneath in order to stop the pool from floating in ground water.

Chlorine is added to swimming pool water to disinfect it.

You can not measure the pressure in a swimming pool. If you mean the pressure on the filter tank gage then you may have to backwash the filter. Talk to your local pool store for instructions as how to maintain a swimming pool and the equipment. Get some education on swimming pool maint. before you get into some real trouble. A pool is not too forgiving for someone without a basic knowledge of pools.

Is this pressure of water going in a filter or pressure of water coming out a filter? Do you mean increase the flow of water? An increase in the filter pressure alone without going to a larger size impeller or newer pump will only indicate that the filter is getting dirty. If you need more flow consider changing the impeller or even upgrading the pump BUT you have to know what the outcome of that change will be. You have to know what the hydraulics and pump curve is in order to keep from overpumping the water. Too much flow can be detremental to the plumbing, the pump, the heater. Going to a large size pump most likely now increase your flow if the pipes can not handle that extra flow of water. Sometimes whrn a pump is not sized properly - going to a smaller size pump or impeller - whichever the case may be - will increase the flow of water or GPM. There is a is a trick or formula for sizing pool pumps, filters and heaters to a particular pool.

The deeper in the pool you go the more pressure the water above you exerts. The popping is your body trying to equalize the pressure inside to the pressure outside.
