To keep the pool clean without a filter, it is necessary to use chlorine with a flocculant or to use a flocculant chemical. This product groups the impurities that float in the water, causing them to fall to the bottom of the pool so that they can be removed later with a cleaner.
Pool pumps typically disperse chlorine into the water for you, but it is possible to add chlorine without a pump. The easiest way to do this is with chlorine tablets. They go in a designated floating container and slowly dissolve while floating around the pool. You can also use inline chlorinators.
Short answer--yes. The first response, however, would be why would you use a pool without a filter? The sand filter or other filtration system is essential to the health and safety of the swimmers. It is also necessary to have a circulation pump for maximum chlorination.
Chemicals are only half of the equation when it comes to your pool water clarity. So yes, while it's perfectly fine to run your pool pump without a filter cartridge installed, it's better to have a backup filter cartridge to ensure that you don't have to run it without one.
A pool can only be safe for swimming without a pump for a few days and a maximum of one week. The definite number of days the pool will be safe will also depend on the temperatures of the water, the weather at that particular time, the level of chlorine, and how clean the pool was before the pump stopped functioning.
Your Pool Will Turn Green
High sunlight, muggy temperatures, low levels of chlorine, or the buildup of phosphates, carbon dioxide, or nitrates can result in a green pool.
Chlorine is used to kill germs and bacteria in pool water, so it plays an important role in keeping the water clear. The pool's pH level, which measures how acidic or alkaline the water is, influences how effective the chlorine is in keeping the water clean.
Shock-chlorination is an essential and effective method of cleaning the pool. But you need to have the pump circulating the water for this to be effective.
Don't bother running electric for an intex pool. They're meant to be temporary structures. Without a pump/filter using your vacuum to move around the water is your best bet.
Intex pools -- the same as with all other swimming pools -- require a filter, pump and the appropriate chemicals, such as chlorine, to keep the pool water clean and sanitary for swimmers.
Potassium peroxymonosulfate: A less costly, non-chlorine shock. Add it directly to your pool water at any time. Takes roughly 15 minutes to work before you can safely swim.
If your kid's pool is pretty small, and draining and refilling it doesn't feel like a colossal waste of water, then the best way to keep the kiddie pool clean is to drain it when the water's dirty, scrub it down with a plain old kitchen brush and some mild dish soap, and refill it.
If you simply do not want to use chemicals to keep your kiddie pool clean, there is an alternative. Rather than chlorine, use Distilled White Vinegar. Add 1/2 Cup for every 100 gallons of water in your pool.
Baking soda will raise the total alkalinity of the water. The alkalinity keeps the pH stable which then allows the bleach to remove more bacteria and contaminates. About a 1/2 of a teaspoon of baking soda will treat 26 gallons of water.
Baking soda is safe and straightforward to use, while also providing your pool with a clean, clear, sparkling water that is pleasant to swim in. Baking soda does not sting the eyes; neither can it cause drying of the skin.
There are alternatives to chlorine including bromine, ionizers, and ozonators, though with each you'll still need to use some chlorine. A fourth alternative is PHMB, which doesn't require the use of any chlorine. All four have drawbacks, including cost. Chlorine is relatively cheap.
It is important to know what exactly bleach is before you put it in your pool. Household bleach, Clorox and liquid chlorine can all be used to sanitize a pool. They are all types of chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine.
If possible, store inflatables in their original packaging; otherwise place them in individual boxes, plastic containers or zip-up storage bags. Choose storage bins or mesh bags for small toys, goggles, snorkels and water guns and noodle caddies for pool noodles.
Clorox itself recommends using between 100 and 200 ounces of regular-strength bleach per 10,000 gallons of pool water -- one gallon is 128 ounces, and many bottles of bleach are available in one-gallon or half-gallon sizes. Pool professionals tend to recommend more conservative amounts of bleach.
After your cyanuric acid level is set, add the bleach. Then proceed with daily testing until you understand how much chlorine your pool uses. At this point, chlorine maintenance can be as simple as adding a little bleach to your pool every day to keep it within the target levels.
If you need to mildly shock a 30,000-gallon pool by raising the free chlorine concentration to 5 ppm, you need 2.5 gallons of bleach. To raise it to 10 ppm, you need 5 gallons.
