Reasons for Salt Level Reading on Salt Cell Pool Dropping Rapidly
Why do salt water pools need to accept table salt added to them on a regular basis, typically twice per pool season? At that place must be a reason(southward) why pools lose salt and need it replaced. I decided to take a closer expect and hither's a summary of what I constitute.
Salt water pools lose table salt from the maintenance of some filtration systems as well as swimming activities such equally splashing and dripping bathing suits. Water leaks are also mutual losses of salt and draining a pool whose h2o level is besides high contributes as well.
Several pop myths also exist regarding salt loss from your salt water puddle and people often assume that information technology's due to reasons that aren't even existent so nosotros'll talk most them in this article too.
Here are 5 reasons for salt loss in your puddle and what you can do to prevent each.

ane. Backwashing your filter
If you ain a cartridge filter you can skip this offset reason. Simply if y'all have a sand filter that requires backwashing keep reading. And if you lot are planning a water filter purchase and are deciding between various puddle filtration systems, you should also go on reading because this is a major downside to sand and other pool filters:
Backwashing.
Backwashing a filter means that you lot rinse the filter out to remove contaminants that have accumulated past using h2o from your pool that is run through a hose and exiting typically on your lawn or driveway.
The purpose of a pool filter is to remove small contaminants and droppings from the pool water as it passes through the pump and chlorinator before returning it to the pool. Over fourth dimension, the filtration system gets total of debris, the internal pressure of the filter raises, and its power to filter droppings decreases. It'southward similar a garbage bin that gets full and needs to be emptied.
Every time you use the Backwash features, information technology runs water through the sand inside the filter to clean it out. Each aftermath bike typically means running water out of the pool for about 2 minutes or until the h2o runs clear on the sight glass on the filtration unit of measurement. This can mean 150 – 300 gallons of water lost during this time, including any common salt that is independent in that water.
It's usually recommended to backwash your filter once the pressure on the filter increases by around 8 psi – 10 psi over the starting level. This may occur every 14 days or so during the summer season. So information technology'southward important that you write down or marking the "normal" starting pressure level on your sand filter right later on it has been backwashed so that when it goes up by viii psi – 10 psi in the side by side few weeks, y'all can backwash again.
A sand filter as well uses a Rinse feature that is used in one case backwashing is completed. It usually lasts for 30 seconds – 1 minute in length and involves flushing more water out of your pool through the filter to flush out whatsoever last debris and contaminants from the filtration unit and pipe which once more leads to more water and salt loss.
Cartridge filters do not crave backwashing simply instead require occasional rinsing of the cartridges which are the filter mediums themselves. You remove them from the filtration unit and launder them off so the loss of salt in this instance is minimal.
Solution
If yous accept a puddle filter arrangement that requires backwashing, carefully follow manufacturer instructions and just backwash equally frequently every bit is required. Over backwashing is common among pool owners and not but does it lead to more water (and thus table salt) loss, it tin throw puddle chemistry out of residuum which takes fourth dimension and effort to get back in line. Plus some jurisdictions pout on excessive pool water dumping into sewers which tin can cause y'all grief if a neighbor reports you. When it's time to supersede your pool filtration organisation, yous might consider a new one that doesn't require backwashing such as a cartridge-based model.
2. Spillage from splashing
Swimmers and particularly kids enjoy pools and splashing is one of the activities that frequently occurs. Jumping, diving and doing cannonballs besides adds to water loss. If you lot have a water slide it's probable that can add to splashing and further h2o loss which too reduces salt.
If you accept a vinyl puddle and the liner starts to come away from the side of the pools which is common over time, splashed water can stop up spilling behind the liner and running down to the lesser of the puddle foundation. Over time the h2o evaporates or is otherwise lost to the pool which again contributes to both water and salt loss.
If yous accept a waterfall or water characteristic that throws h2o high in the air, a windy day can help to contribute to water loss as well. Information technology all adds upwards.
Whatsoever fourth dimension you accept water loss like this, you volition have salt loss too. It'south just a reality of pool ownership.
Solution
Probably not much y'all tin do here. Pools are meant to be enjoyed and how tin you lot prevent kids from splashing around and having fun? Compared to water loss from a backwash, information technology's relatively small-scale too.
3. Water loss from bathing suits
People – particularly kids running in and out of the pool frequently – often runway a smashing deal of water out of the pool when they bound in and out repeatedly. Adults take even more than water out because they tend to be bigger and article of clothing bigger bathing suits that concur more than water.
This is again a reality of having a pool but it farther helps to explicate why salt is lost from a salt water pool.
Solution
Probably not much you can practise here either. Information technology'south merely a reality of puddle buying that occurs and leads to both some water and salt loss. Just an FYI in case you're still wondering why you lose salt.
4. Water leaks in your puddle
This is a big ane and a reason that can be limited if not outright prevented. If you lot have a vinyl puddle, the liner can tear or rip and information technology can pb to water loss and leaks.
The concrete base of your pool can scissure and leak as can secret or above ground piping.
A heater can leak and cause water loss every bit tin your pump. This tin can occur from either the pump itself, around the seals of piping or fifty-fifty the skimmer basket if the brackets get loose and allows air and water to escape.
Your filtration system can also leak h2o if a valve gets loose or something isn't tightened correctly.
Again, over time information technology can all add upward to h2o and common salt loss.
Solution
During pool flavor, h2o will evaporate naturally so information technology's common to see noticeable water loss within several days of hot sunny atmospheric condition. Information technology's non uncommon to see a 0.25″ to 0.v″ water loss in a puddle on a daily basis which means a loss of 1.75″ – three.five″ of h2o per week simply due to evaporation.
While evaporation won't reduce salt content it tin can hide the fact that you are too leaking water. It'due south important to familiarize yourself with "normal" water loss to notice when abnormal water loss occurs to spot a leak quickly. Inspect your pool daily and ensure brackets on your filter and skimmer baskets are tight and that there are no puddles or drips that shouldn't exist.
5. Draining your pool level
After a heavy rain storm information technology isn't out the question to see a water level increment up to several inches to the point where the water level is too loftier. A normal water level can typically be determined by eyeballing the skimmer on the side of your puddle. Water should be able to menstruum into the skimmer nigh 1/two to iii/4 of the mode up the skimmer.
All you can do when the water level is too high is either wait for the water to naturally driblet through evaporation and other things we've spoken about higher up. If the water is besides high and needs firsthand action, yous accept to drain h2o out. Draining water out of grade will also remove salt.
If the water level gets higher than the top of the skimmer, not just will the skimmer not properly skim the surface of the puddle and draw debris in which is its purpose, the higher water level tends to lead to more h2o and thus salt loss through splashing, diving, jumping, etc.
Solution
Before draining h2o out, only do then when it's required. I've constitute that afterward a summer storm raises h2o level too high, the normal water loss that occurs in summer typically takes care of things and water level will naturally fall without draining. But if your pool is close to inundation or is above the pinnacle of the skimmer, y'all're probably going to demand to drain some off. And salt will exist lost.
A few salt water puddle myths busted
While we have discussed the v main reasons that salt is lost in a common salt h2o pool, there are a few reasons you lot may accept heard that aren't correct.
Salt doesn't evaporate
Some people call back evaporated water leads to table salt loss but information technology does not. When water evaporates the salt level doesn't change. Water evaporates but salt doesn't.
In fact other than losing table salt in the 5 ways mentioned above, if you practise need to e'er lower table salt level in your pool, it's generally done by draining water out and replacing the lost h2o with fresh unsalted h2o. Information technology won't happen by evaporation.
Salt doesn't wear out
Salt also doesn't wearable out or die. While the salt prison cell that processes your salt and converts it to chlorine will die and end upwardly needing to exist replaced, y'all supersede salt in your puddle because of common salt loss for the reasons described above and not considering the table salt dies out.
Summary
Salt replacement in a salt water pool occurs on an as-needed footing. Having a salt h2o chlorinator system that measures a live salt reading is handy to keep you lot informed as to current salt levels and then you tin can add salt if needed.
Information technology's important to note that it's easier to add together salt to a puddle than remove it so practise be careful when adding salt and simply do so when needed. The platonic salt level in a salt water pool is 2,700 ppm – 3,400 ppm with 3,200 ppm beingness a goal that is skillful to aim for.
