How much does it cost to run the saltwater generator?

That’s a fair question but difficult to directly measure and complicated to estimate but here goes.

The average unit is rated between 4 and 7 amps depending on current operating conditions (temperature, bather loads and chlorine production setting). Let us use 5 amps as an overall average which would probably be high for the average pool.

So the math goes
5 amps X 120 volts = 600 watts per hour = .6 Kw
At $0.11 per KwH = .6 Kw X .11 X 24H = $1.58 per day
From end of May till end of September = 120 days
So 120 days at $1.58/day = $189.00 per season.

This is the MAXIMUM that a person could expect to pay. It is based on running at 100%/24 hrs a day for the entire season.

By the way, the pool pump is also rated at 4 to 7 amps and runs at around 5 amps also, so this is the approximate cost of the pool pump to you seasonally. That is why most people put timers on their pumps and run them 12 Hrs per day and realize a savings of around $100 per season on their electricity bills.

What type of salt should I use?

The best type of salt to use is Sea Salt (NaCL). This type of salt contains the least amount of impurities and is normally sold at Pool Shops, Hardware Stores, some Supermarkets or Farm Produce Merchants.

In Canada at this time, sea salt is difficult to obtain and can be expensive. We do however have very pure salt deposits in Goderich Ontario which supply us with a salt source which is almost as good as evaporated sea salt. We must caution that some salt sources contain manganese which will cause brown stains to form on your pool if used. Salt which has a flowing agent (YPS or Sodium Meta-Silicate) must not be used. The use of this agent will cloud and foul up your pool.

Sifto "Crystal Plus" water softener salt does not contain any impurities or additives which will damage your pool equipment. There is finer salt available but you must ensure that it does not contain harmful additives.

"Crystal Plus" will take a little longer to dissolve, (about 24 hrs), but you will have the comfort of knowing that you are not creating problems down the road.

Some customers have asked if Potassium Chloride (KCl) can be used. YES it can but it is far more expensive, usually around five times the price of Sodium Chloride (NaCL). The type of salt that you DO NOT want to add to the pool is Salt that contains a Free Flowing Agent (containing Sodium Meta-Silicate) The use of this agent will cloud and foul up your pool.

When can I convert my pool over to salt water?

Any pool can be converted over to salt water at anytime of the year. It simply requires the installation of the chlorine generator cell on the equipment pad and the addition of the required amount of salt to the pool. The spring would be prudent since all of the previous chemicals that had been added before would be dissipated from the water and you would have very little stock of previously purchased chemicals that will no longer be required.

Do I need to drain the pool and refill it with new water?

Absolutely not!! There is nothing wrong with the water in your pool. After all you’ve been swimming in it for years now haven’t you? This is just another way of chlorinating your pool for sanitation.

Where do I add or put the salt for the pool?

Salt is simple poured into the pool to get the start up level required. If your pool has a jet on the step, it is best to dump the salt onto the step and allow the water flow to dissolve the salt quickly. If you do not plan to swim right away, the salt can be dumped into the shallow end of the pool and brushed around to speed the rate at which it dissolves. If you want to swim right away, put the salt in the deep end of the pool. In a vinyl lined pool there is a risk of tearing the liner if a large piece of salt is stepped on. In the deep end, the salt will take longer to dissolve (as much as 2 days for water softener salt).

How much salt do I add?

Watermaid recommends a salt level of 6000 parts per million (PPM).

PLEASE NOTE: If it is an existing pool that has been running on chlorine or bromine, test the salt in the pool before adding any more. It is common to have a salt level of 2000 – 3000 ppm already. These compounds are salt based and accumulate in the pool.

It takes 6 grams of salt per litre of water to make 6000 ppm.

Sample calculation
from the chart a 16 x 32 oval = 66500L x 6g/1000 = 399 Kg salt
399Kg / 20Kg (1 bag) = 20 bags of salt

Do I need to add anything else to the pool water?

Watermaid recommends a one time addition of 15 to 20 kg of magnesium sulphate (Epsom salts) to your pool. This will make the calcium deposits that build up on the electrodes in the cell mushy and allow them to slough off easier during the self-clean cycle of the unit or when you manually clean the cell unit. I have prepackaged magnesium sulphate available for sale.

Why should I install a saltwater chlorinator?

Just for starters it is much cheaper to own. A saltwater chlorinator will eliminate the high expense associated with regular purchases of biocidal chemicals. And it will eliminate the need to find a safe place to store these dangerous chemicals.

Why should I use an isotonic pool water solution?

The simple answer is an isotonic pool solution is extremely pleasant for relaxation…it feels good…even after long periods in the pool. But there's another reason.

It's just a shade safer for the children.

Why should I install a Watermaid?

That's easy. Watermaid has been designed to use the best of the long-life materials that are available and the most reliable components. It carries a full unconditional 5 yr warranty, the best in the industry. It's the best chlorinator on the market and the only one that has been explicitly designed for use in isotonic pool solutions.
