The Compupool CPSC/CPA Series is recommended to run at a salt
concentration of 3500 ppm. If you are not installing a Compupool unit,
check your manufacturer’s instructions for their recommended level of
concentration . Use a salt that is at least 99.8% pure NaCl. The
preferred salt is an evaporated, granulated, food quality, NON-iodized
salt. Avoid using salt with anti-caking agents like sodium ferrocyanide,
also known as yellow YPS (prussiate of soda. These cause some
discoloration of fittings and pool surface finishes. DO NOT use calcium
chloride.Using a salt water test strip, measure the current salt level of your
pool. For the Compupool generators, ideal is 3500 ppm. If the level is
low, determine the number of gallons in your pool and add salt according
to the Salt Table. For example, if your pool has 15,000 gals of water and your current salt level is 2500, you need to add 125 lbs of salt.

How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

If you`re converting to a salt water system for the first time, you`ll need about six or seven 40-pound bags of pool salt (for a 10,000-gallon pool). On the other hand, if your salt levels are just low (around 1,000 PPM), you`ll only need about four or five 40-pound bags of pool-grade salt.
To produce chlorine, the chlorinator requires salt. We recommend 5 kg of salt per m3 of water for a Normal Salt mode (NS), 2,5kg per m3 for a Low Salt mode (LS) and 1,5kg per m3 for Ultra Low Salt mode (ULS).
How much salt to add to the pool? To reach the initial salt level recommended by the salt system manufacturer (usually 2,400–3,200 ppm), you will need to add about 200 pounds of pure pool grade salt (NaCl), per 10,000 gallons of water. This dosage will get you to approximately 2,400 ppm salinity.
It takes about twenty-four hours for dissolved salt to dissolve sufficiently, so leaving the pump on during this process helps. Test the salt level of the water periodically until it reaches 3500 ppm or the required level as set out in your manufacturer`s instructions.
A salt pool changes salt from the salt cell into chlorine instead of having to add chlorine directly into the water. It is okay to shock your saltwater pool and it is important to do so.
Given that your pool`s chlorine demand can have such variation, most pool owners will want to choose a salt chlorinator with a maximum capacity 1.5 times to 2 times your actual pool size. For example, you may want to choose at least a 30,000 gallon max capacity system if you have a 20,000 gallon pool (1.5x more).
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level. If the level is low, determine the number of gallons in the pool and add salt according to the chart below.
How much salt do I add to a 15,000-gallon (56,800-liter) pool? If we have a 15,000-gallon pool containing only freshwater, we`ll need to add about 400 lbs (180 kg) of salt, to achieve the recommended salt concentration of 3200 ppm.
In that case, You`ll need to add 30 lb of salt for every 1000 gallons of water. Therefore, if you have a 20,000 gallon pool and want to determine how much salt you`ll need to buy, you would use the formula “30/1,000 x 20,000”, which equals 600. Meaning, the pool would require approximately 600 lb of salt.
You will want to have a total chlorine of 1.0 ppm for 48 hours for the salt water start up. The shock and the primer are put in together. One bottle of Pristiva Premium Shock per 20,000 gallons or 80,000 liters.
Crank up your salt water chlorinator

Since it`s summer, set your salt water chlorinator to 80% to 100%. You`re going to need all the chlorine you`re going to get from your unit as your pool will need it due to a number of reasons: UV rays from the sunlight will “eat” your chlorine faster.

With a properly sized filter and salt chlorinator, run times of 7 – 8 hours will generally be necessary. The defining factor governing filtration times in a salt pool is usually determined by the size of the filter/ioniser and the need to make sufficient chlorine.
Not Keeping Your pH Levels In Check. Your pH will run on the high side in a salt water pool because your salt water generator naturally raises your pH as the system runs. High pH levels above 7.6 can lead to skin irritation and burning eyes and cause scaling on your pool equipment.
As a rough estimate you want to be aiming at around 3,400 ppm (parts per million) for your pools salinity. For every 1,000 ppm increase in salinity level, you need to add 10kg of salt to 10,000 litres of water. For example, if your pool contains 20,000 litres, you need to add 20kg of a 25kg bag of salt.
The concentration of salt in a swimming pool should be between 4 and 5 grams per litre of water; Therefore, it would be necessary to add 4 to 5 kilos of salt for each m3 of the pool.
No matter what brand you buy, you want to oversize your system. The industry standard is to choose a salt system with a maximum capacity of 1.5 to 2 times the size of your actual pool (ex: for a 20,000 gallon pool, choosing a system that can handle up to 30,000-40,000 gallons max).
Add 80 grams Bluewater Granular Pool Chlorine per 10,000 litres of water.
For safe swimming conditions, the ideal salt level is going to be between 2500 ppm and 4000 ppm. An overly salted pool will generally not be a major problem (aside from salty-tasting water), but at levels, over 6000 ppm there may be corrosion damage to some of the metallic equipment.
Saltwater Pool Advantages

Because they have lower chlorine levels, saltwater pools are gentler on the eyes and skin. Research indicates that saltwater systems may be safer than chlorine pools, which require pool owners to store and handle harsh chemicals.

Also, do not test for or add salt (at least large quantities of it) until the water temperature hits 68-70 degrees.
The only way to lower the salt concentration of your swimming pool`s water is to dilute it. Unfortunately, this means you will need to partially drain your pool and refill it with fresh water. This is true because salt doesn`t wear out, break down or evaporate; only your water will evaporate.
If you`ve got standard chlorine tablets (200g each), you`ll need one tablet per 20,000 litres. So for a pool that contains 60,000 litres of water, you`ll need 3 tablets every week to keep it sanitised.
After Shocking Your Pool

It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.

I have a multifunction sports watch that i bought from Big W, (no brand name)

By accident i set the watch to 24 hour time, originally it was set to 12 hour time, how do i set it back? ive tried every button combo including the button combo i used when i accidently set it on 24 hour time, the instructions only say how to set the time and date, it doesnt say how to toggle between 12 hour and 24 hour time, is there a generic way to toggle it on sparts watches? btw, holding the mode button in does nothing on my watch, no matter how long i hold it in for

ANSWER : Hi. How may buttons do you have, 3 or 4 buttons?if you have the 4 buttons, try this:You need to go through the time and date settings again. The 24 and 12hr format select is at the end of time/date adjustment.To set the time and date:-press the top-left button then right-top button to set the seconds, press bottom-left button to set hour then press top-right button to adjust hour, press bottom-left button to set the minute then press top-right button to adjust minute. To set date, press the bottom-left button then press top-right button to adjust month, press bottom-left button then top-right button to adjust day and finally press bottom-left button to set the time format then press top-right button to select 12hour format. Press top-left button when done.Since you have a generic sports watch, it is hard to write specific instructions to set the time format. If your watch has different ways of setting the time, just remember that the 12/24hour format is usually at the end of time and date adjustment.Let me know if you have questions. Good luck.

Intex pool not compatible with Polaris vac-sweep cleaner
ANSWER : Polaris should have an adapter to make it fit, I’m surprised you didn’t get one, usually an adapter is put in a box to make it work with multiple pools, you can call them and order one or go to a local hardware store or Menards and make your own. They will have PVC fitting adapters. You should be able to find one that will work which you may need to permanently attach it on the one end and custom fit it, but if you have basic skills, then you shouldn’t have a problem with getting it to work. Let me know how this turns out.Benjamin

My swimming pool. I have just had my fifth IC 40 Intellichlor chlorine generator installed in 4 years at a cost of over $900 today. Each one has worked for no more than 8 months. The first three were replaces under three year warranty, the fourth by a factory rep and I bought the fifth today. The first three all failed with Flow Chk PCB error message. The fourth just stopped working on Sunday, no power or lights. A local Pentair warranty person, whom I paid a Service Call, unplugged the unit, opened the small power center cover, showed me the green light indicating that there was power, plugged in a new IC 40 which worked immediately (as did the other four). I asked if I should replace the power center and he said that it’s basically just a transformer and is working fine. We do get occasional power blips that make the clocks on microwaves, etc blink, but I thought that the power center essentially isolates the cell from these. I do have a Florida Power and Light surge protector on the electrical box that brings power into the house. I have now talked to the pool builder, two Pentair warranty repairmen and one factory rep. I am at a loss. They all tell me they have no idea why these units fail after less than a year. This last IC 40 was installed 3/24/2010, version 2.0 and now failed in less than 5 months. Should I replace the power center that the IC 40 plugs into. Any other suggestions. I have been told that this is the best chlorinator. I don’t want to keep replacing units. By the way, each unit had been spotless inside. I keep the water chemicals and salt levels at ideal levels. The units have never worked long enough to get dirty inside. The power center is connected to an Intellitouch control system outside with an indoor control panel. Last time I called Pentair North Carolina and got some smart alec tech person that had no suggestions. Please Help if you can.
ANSWER : I’ve had the same experiance. On my fifth one as well. Fail every year. No idea why.

Have an Intex 12ft x 3ft metal frame pool. Set it up first and filled it and it lost more than half the water overnight. Did everything I was told to find the leak and nothing. Was on hands and knees in pool with blue dye dripping slowly here and there to see if it is sucked through pin holes since I couldn’t find a tear at any seams. Sent back pieces for a replacement liner. Two weeks later we have a new liner fresh from California and are having the SAME problem. What could be going on? The hours we have wasted in this leveling the ground putting up, taking down and putting pool up again… the cost of the water to fill it up twice. This seems to be quite the bottomless money/time pit. Any suggestions?
ANSWER : What is not included in the instructions is the simple ” lay down a bed of filter sand around 3″ thick before placing liner in the pool frame and radius it up at the bottom corners
that sand is necessary because any small pebble , rock or edge will cut the thin liner under water pressure or feet walking in the bottom of the liner
further more , if you use chlorine as a cleaning , antibacterial agent that will cause pin holes in any part of the liner not completely covered by water

I have Detroit 60 series installed on a launch. Recently the Starboard unit suffers a catastrophic failure and piston No2 came out of the block, making a big hole. This engines are using heat exchangers, and sea water cooled Charge Air Coolers and sea water self priming raw water pump. We contact the local dealer an the veredict was a “Massive salt water ingestion” that caused an Hydraulic lock and damaged cyls 6 and 2. They say that the water came from the deck covers, but there is no way for that to happen, I think they dont want to honor any warranty, because we suspect that the water came from the Charge Air Cooler. I want to know if the CAC can cause that type of failures and if anyone had a similar problem. The engine cost is about 66K and only had 2300 hours.
ANSWER : I would have to say that a sleeve got pitted or lost an oring or the CAC sprung a leak. I believe you are correct in your assumption that the water did not enter the unit in the manner they are saying. The only real way to tell is a complete tear down and someone is going to have to pay. They are also a high maintenance item and someone is going to say that the preventive maintenance was not done.
