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.
In most cases, you can operate the cartridge pool filter without the filter cartridge inside the tank just to maintain circulation as you wait for the cartridge to dry. However, doing so requires you to ensure you've removed all the internal parts and reassembled the tank tightly.
When you cannot circulate water, the water stagnates and chemicals tend to settle out in the lower levels of the pool. It makes it almost impossible to add any chemicals because you don't have a good way to mix the water.
Your pool can keep running for a few days with no problems while without a pump. However, know that a standard pool needs a pool running for at least once in 24 hours, or you might notice an algae bloom. So, it's best to have your pump ready as soon as possible.
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.
If you are without power, grab your pool brush! Not only will scrubbing the sides and bottom reduce or prevent algae, it also causes the water to move and circulate, helping maintain an even level of chlorine throughout the pool.
If you are going to have a swimming pool, you must have a filter system that collects all the debris that can accumulate in a pool. In most areas there are actually legal requirements as to how quickly the water in the pool must go through the filtering system.
Filters clear out the tiny particles that threaten to make your pool water gross to swim in. Without a highly functioning one, destructive debris will build up over time. Every pool owner needs a high quality filter system.
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.
While pool filters do an excellent job of removing contaminants and impurities floating in the water, they can't remove muck sticking to the walls or floor. Pool cleaners that attach to the pool filter perform this duty. Pool cleaners consist of three types: robotic, pressure side, and suction side.
Above-Ground pools are available in a variety of sizes, in Round and Oval shapes. Depths range from 48" to 54".
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
Filter Size
The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it's best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.
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. Household bleaches often have unwanted fragrances and colors.
Short answer: yes. Longer answer: it depends on the formulation. The label on every bleach bottle should tell you the ratio of sodium hypochlorite (and available chlorine) in the bottle to everything else. A higher percentage is generally better, as you'll need to use less bleach to treat your pool.
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.
Length x width x average depth x 7.5 = volume (in gallons)
Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic meters. If you'd like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
Of the three main types of pool filters, a cartridge filter uses the least amount of water.
A 15,000-gallon pool needs about 20 GPM output if we want to run it 24 hours per day.
Deciding when to change your pool water is important. Most in-ground pools should be drained and have the water replaced every five to seven years. How often you drain your pool depends on a couple of things: Maintenance and upkeep.
