The water becomes aggressive and can etch the plaster and metal parts of the pool and equipment.
The water becomes aggressive and attacks anything with which it comes in contact. Not a good environment for the pool finish or the equipment.
Potash
A cork has a low density. It is lower then water. That causes it to float.
Not likely, make sure all chemicals are balanced. If still cloudy, use a clarifier sold at pool stores.
Low suction from your pump, damaged hose,
A drained swimming pool will be more dangerous to anyone who could fall into the pit. The pool will need fencing around it that is sturdy and anti-tamper proof. What are your plans for rain water when it fills during a storm? What are your plans for when you have a lot of rain and the water table surrounding the pool rises enough to make the pool float out of the ground????
Add rain water this has very low alkalinity
You can buy a testing kit and test your water to see if there are any abnormal bacteria in your water that would be keeping the chlorine levels low. Otherwise, just add chlorine daily to keep your pool safe for swimming.
low to mid 20's should get you swimming w/a 4ft. deck around the pool and the site graded.All is dependant on how big and the site and the xtras(auto cleaners etc.) The figure should be good for an 18x36ft. pool 3x5ft. deep on a reasonably flat lot.
If the water's chemistry is not correctly balanced, it can. For example, if your pH is too low, the water can etch cement you'd materials.
That is the correct spelling of "pool" (a collection of water, a slang for billiards, or to gather together).
Two reasons: First, the volume of a human body is quite low compared to the volume of even a moderate sized swimming pool. If you jump into an Olympic-sized pool, you're only going to increase the water depth by a small fraction of an inch. Second, they have overflow drains to prevent it.
