There are several reasons why a pool can be cloudy.
There may not be enough free chlorine in the water.
The filter system may not be running enough to properly clean the water.
There may be too much calcium in the water.
The Ph may be too high.
The filter system may be compromised.
my pool did get milky but cleared up after 48 hours
It's best if the water is cleaned before you close up the pool.
You may have a high metal content in the water you are using to fill the pool. Check the metal content of the water.
Your pool water may have turned green even after adding Fresh and Clear because of metals in your water. It is likely copper that is causing the water green. Your pool store will have products available to remove the metals and clear your water up. You might also have algae if you are not putting enough chlorine in the pool.
Drain it and refill it
I too had milky water in my pool. I also have a chocolate lab dog who loves the water. I found that with allowing the dog to swim would turn the water milky and that a "slime" would develop on my filter and in my filter housing. I can't deny the dog but I can limit the number of swims. My pool is small so it's not hard for me to fix. I change the filter or clean it real well every day for a couple of days following one of her swims. I also heavily "shock" the water at the end of the day for 2 days after her swim. If the cause of you milky water is a 4 legged friend, this has worked for me. New answer:: Ah, yuck! Do you realize the germs on a dogs body. Milky and slime more YUCK! Extend the filter run time if you insist on having a dog swim in your pool. As a pool service person, I wouldn't even put my toe in the pool under those conditions. Milky water is caused by many things but lack of filtration is one and lack of a sanitizer is another. You are subjecting yourself to a multitude of germs and bacteria. Diarrhea, e-coli are but a few found in pools. Oh, horrors of horrors! K
Pour in a gallon jug of algecide and increase the amount of chlorine you use and run your pool's filter at least 6 to 8 hrs a night. Will clear up in a day. Of course this info depends on size of pool, but the average 16,000 gallon pool will clear up.
If it is there you may see it in the water giving it a green or milky colour. It can also build up on the surfaces of the pool and need to be scrubed off.
Your water is turning green due to algae. You need to scrub your pool walls to and then "Shock" your pool by adding chlorine. Keep your pool filtered and it should clear up in a few days.
Use a floculant you will be able to get this at your pool shop You wil end up loosing a litle water but it is the best way to get the water crystal clear.
maybe someone threw up in it... lol
Watering a plant with any type of salt water will cause the plant to wilt. Because of the salt outside the plant cells, water leaves the cells in a process called osmosis. With less water in the cells, the cells shrivel up. If they shrivel up, the plant loses it's ability to hold itself up.
