OH YES! Here is my favorite saying when it comes to this question. "You don't want to swim in the water you drink and you don't want to drink the water you swim in." When the city sanitizes the water they usually inject the water with ammonia to slow the chlorine's reaction rate down so that the chorine lasts longer. This works great when the water is underground and protected from the outside environment. Once the water hits your pool the ammonias they injected are going to create problems for your pool water. The only way to get rid of ammonias is to shock treat the pool. If you are filling the pool with well water or artesian well water DO NOT SHOCK THE POOL UNTIL IT HAS BEEN TESTED FOR IRON BY A SWIMMING POOL PROFESSIONAL. Failure to do this can lead to the pool surface of the pool being stained. And that boys and girls is why you want to shock your pool after it is filled.

∙ 13y agoShocking your pool will break up chloramines or organic compounds that bind to chlorine. You will be able to tell if your pool needs this because it will have a raw chlorine smell to it. The organics are introduced by swimmers, dogs, birds, debris from the ground, tree's, you get the idea. The shock will free up the total chlorine which is the reading you see on your chlorine test. After you add the correct amount of shock the super chlorination will dissolve the organic compounds and free up the total chlorine, which is also called break point chlorination, and the total chlorine will be come free chlorine thus making the water clear and fresh. Once a week is the preferred time frame and always wait 12 to 24 hrs before swimming unless you are using a quick swim shock.

∙ 11y agoMy family and I use a non- chlorine shock before adding the salt to the water. We do this because we want to disinfect the nasty stuff storage leaves behind. This way the chlorinator doesn't seem to work so hard. The shock says you can swim 3 hours after you use it. Our pool is crystal clear and ready to go! Hope this helps!

∙ 11y agoSand will remove more than 90% of microbial contamination of water. This is effected by the surface charge on the sand particles it's like a cloud of electrostatic charge on the surface of the granules of the sand which then attracts the opposite charges on the surface of the microbes. This is different to the exclusion size of the sand characteristics.
90% is a lot of contamination but so can 10% residual be a lot. It depends on the microbe population as to what is dangerous. eg: e.coli is considered dangerous beyond a certain count for swimming. Algae is effectively removed by sand filtration but the bloom rate can be greater than the effective exclusion rate of the filter so there may still be a net increase of the algae. Algae is killed by a shock treatment
Organic contamination of the water is a consideration here. If the organic is noticeably particulate, it is good to remove this by mechanical filtration first. This is because a large amount of organic material can neutralise hypochlorite and effectively wipe out the available reactive chlorine, renedering it ineffective.
Shock treatment with chlorine by hypochlorite is a wise treatment after initial filtration. This will reduce the microbial level down to a reasonable and safe level. The hypochlorite concentration must be maintained for a minimum period to guarantee effectiveness. Not all microbes are killed by hypochlorite/chloramine treatment, but the residual level of non-sensitive organisms isn't considered harmful for people of average health.

∙ 11y agoNo shock needed after heavy rain however, you may need to add sodium carbonate. Rain water not loaded with essential minerals to maintain proper alkalinity of 100 ppm.thus, rain water may lower alkalinity and reduce available chlorine. Add baking soda to raise alkalinity and add chlorine if needed to the proper level of of 2 to 3 ppm

remember to not open you eyes in it without gogles

How do you chemically clean the sand in a pool sand filter?
Here's a quick tip on chemically cleaning or killing the algae living in the sand in a sand filter. The next time you shock your swimming pool, poor the shock or bleach in the skimmer. This will provide a very high level of chlorine in the filter for a very short period of time. Long enough to kill the stubborn algae living in the filter but not long enough to hurt your plumbing.
Some sand in bottom of your pump from vacuuming pool above ground is this normal?
If you are getting sand coming into the pool and have a sand filter you may have to replace worn laterals in the sand filter.
What has gone wrong if there is Sand in filter?
Nothing if its a sand filter However if sand is coming into the pool from the filter then you may have to replace one ore more laterals in the sand filter as they have worn and are letting sand through to the pool,
How much sand do you need?
For what? Building a cove for a vinyl liner. Adding sand to a sand filter. Building a sand box. For the base of a pool. ????
Why do you have sand in your gunite pool?
If you have a sand filter the laterals in it may be starting to show signs of wear these wil blow sand from the sand filter into the pool when they wear out.
What happens when you put brown sand in a pool filter instead of white silica sand?
It could damage the internal PVC of the filter and cause sand to get in your pool.
Pool sand filter is making your pool green?
The sand filter wont make a pool green this happens a s a result of algae.
Is low sand in pool filter bad?
It depends on what you mean by low. You need to check your filter's manual, and see what level it SHOULD be. Lower than that, usually means you are losing sand into the pool (you'll know!) or when you backwash (because the pump is too big for the filter.) If you are losing sand, you need to correct the cause and then add more sand, after you've resolved the problem.
Why did your pool water turn brown right after you put shock in it?
Sounds like it may have cleaned up some pipes and/or filter sand. If that's the case, be sure to backwash your filter.
Why is my SAND filter pressure increasing so quickly?
Possibly you are in need of new sand or you can go to the pool shop and ask if they have a chemical sand cleaner.
How do you change a vinyl inground chlorine sand filter pool to a salt?
Need to rephrase question.
If you put a sand beach next to your in-ground gunite pool will the sand that ends up in the pool cause problems with the filter?
If you have a sand filter as your filter you may need to remove some of the sand from time to time, But most will be dunped during backwashing. If you have a cartridge filter you may have to clean it more often. If you use D.E. the sand will be dunped when you backwash,Other then that there is no harm. A: Why would you want to be tracking sand into your clean pool? You are just adding more contaminants. YUK !
