Tips & Guidelines to proper operation of a salt system (Under Construction at bottom of page)

A Salt-Water Pool is Often the Pool of Choice

It can be complicated deciding which pool is best for your family. Many questions revolve around salt-water pools or chlorine free pools. Salt-water pools are NOT chlorine free pools. A salt-water pool is simply one that utilizes a chlorine generator. Chlorine generators have been around for decades. As technology and materials continue to evolve, chlorine generators continue to improve in performance.

Why Salt-Water?

Ocean water has a salt content of around 35,000 parts per million ("ppm"). Humans have a salt taste threshold of around 3,500 ppm. Most chlorine generators require a salt content of 2500 - 6000 ppm in the pool. A unit that needs less than 3500 ppm to operate effectively is optimal. If the salt content is higher, that warm, salty water will be pretty distasteful!

Swimming in a mild saline solution is much like taking a shower in soft water. Generally, when people swim in a non-chlorine generator pool (a pool with no salt water in it) they feel like their skin dries quicker upon exiting the pool. They may feel and/or see a whitish residual, chlorine flaking, on the skin. In a salt-water pool (one with a chlorine generator) the water feels smooth, your skin feels smooth and many people feel more refreshed.

What Does a Chlorine Generator Do?

A chlorine generator's main function is to produce chlorine for the pool so you do not have to buy it, store it or handle it. These are big advantages for many pool owners. Chlorine generators, when functioning correctly, produce chlorine constantly (when the pump is running) with most units. This keeps a residual of chlorine in the pool that prevents algae from growing. The secret is keeping the cell free of calcium and mineral deposits--the cell itself is made up of precious metals-it must be maintained so it can continue to make chlorine.

Through the process of electrolysis, water passing over the chlorine generator cell produces chlorine that is instantaneously transformed into Hypochlorous acid. When any type of chlorine is added to water it ALL makes the SAME thing: Hypochlorous acid. It does not matter if it is Sodium Hypochlorite (liquid chlorine), Tri-chlor and Di-chlor or Lithium based, Cal-hypo or even gas chlorine--it all makes Hypochlorous acid. Hypochlorous acid is the active sanitizer; this is what kills algae and other harmful stuff in the water. Its effectiveness is totally predicated on balanced water conditions and, more importantly, proper pH. So, with a salt water system or chlorine generator, you still must maintain your water balance (pool chemistry) properly. As long as you do this, a chlorine generator is a good choice.

Types of Chlorine Generators

There are two types of chlorine generators in use today on residential pools. The first one is a brine unit. This unit does not require the pool to have salt added to it. A tank or chamber at the pool equipment area has a predetermined amount of salt in it. Through electrolysis, chlorine is produced and immediately injected into the pool circulation system. These units are messy and produce by-products that are not simple to dispose of. These are the less common of the two types.

The recommended unit is the type requiring that salt be added to the pool.

We install the Goldline AquaRite Salt System on aftermarket installations. Other systems are available if  integration is required with electronic control panels.

There are two types of these units. One has the chlorine-producing cell and the electronics installed at the equipment while the other has the cell installed in the deck near the pool with the electronics usually located at the equipment. The deck unit works on the principle of convection. It makes chlorine even if the pump is off while the other more common unit makes chlorine as water is passed through the cell with the circulation system (pool pump on.) In both cases the cell must remain free of mineral deposits or it will not work properly. Of these two units, the inline unit with 24-hour circulation is the preferred choice. (Did you know that every commercial swimming pool in the United States requires 24-hour circulation?)

What About Polarity?

There are non-reverse polarity units and reverse polarity units. A reverse polarity unit reverses the electron flow through the cell causing mineral deposits to flake off. In some instances the now larger particles will get caught in the filtration system. So the claim that the units help keep calcium scum off the tile is partially correct. These cells do not require as much cleaning. (Don't believe a claim that a unit doesn't ever need to be cleaned) A reverse polarity unit will cost nominally more than a non-reverse unit.

Bottom Line

Chlorine generators can help fight against waterline scum build-up. They create a better, healthier swimming experience for most people. It isn't necessary to handle or buy chlorine, and, if the unit is functioning correctly, chlorine residual will always be present in the pool, eliminating algae. This makes it nearly impossible to get burning red eyes from chloramines, which is usually the culprit. Even with a chlorine generator, you still must maintain your pool. You still must maintain correct water balance, and you must maintain the chlorine generator. The best pool will have 24/7 circulation, correct hydraulic design with an in-floor cleaning system for bottom up cleaning and circulation, a quality ozone system, and a chlorine generator for sanitizer residual. You can expect to pay at least $1,000, and up to several thousand dollars, for a quality chlorine generator unit.

DISCLAIMER: If you do not maintain a chlorine generator or maintain your pool chemistry you can destroy your pool's interior finish, decking and pool equipment. Chlorine generators and salt-water pools are great but they need care.

You now have the recipe for a low maintenance pool. Enjoy, and swim safe!

Goldline AquaRite Systems
AquaRite makes it fun and healthy to own a pool -- with new purification and convenience. And with no more having to buy, handle mix or measure chlorine.

That's because AquaRite generates its own chlorine from ordinary table salt -- to create 100% of the purification. You control it automatically through your present filtration system, using a low level of salt and recycling it.

This softens the water giving it a soft, smooth, silky feel you'll love to be in. For fitness and pure leisure, nothing is more convenient. Nothing is more nature friendly.

 

 

Set AquaRite once to suit your preferences, and it purifies day in and day out -- according to the correct just-right balance you want.

The unique design of our TurboCell monitors water flow rate, water temperature and salt level of pool water.

The design also creates a "scrubbing" action to assure the cell keeps operating smoothly for years.

2-inch wide piping minimizes any flow restrictions. The offset design amplifies the water circulation rate, it turbocharges and speeds "scrubbing" action. It harnesses electrolytic co-generation at less cost.

The Aqua TurboCell is simply plumbed into the return pipe to the pool. Its wire is plugged into the control panel and the system is ready to go. When your pool pump turns on, your AquaRite is activated. It then disperses freshly purified water, sparkling clear water with the level of purification you want... a fresh, healthy difference you'll enjoy.

Tips & Guidelines to proper operation of a salt system     Top

  • The main pool pump must be running in order for a salt system to produce chlorine. The average pool should run 12-15 hours with salt system at 40%-70% depending upon bather load & organic demand (trash in pool)

  • Run salt system at 100% for 24 hours before & after a swimming party to ensure water clarity.

  • Be sure salt level is between 2800ppm & 3200ppm at all times. Backwashing, splash out, & overfilling will reduce the salt level in your pool. Use a Salt Test Kit do not rely on the system for accurate salt level. The system bases its reading on water conductivity not the true amount of salt in the water. Most pools will require 50lb.-100lb. of salt every 3 months.

  • The pH level in salt pools is always rising be sure to check pH weekly to prevent scaling. Most pools will need 1/2 gallon of acid every 2-3 weeks. However, be sure that your Total Alkalinity does not fall below 80ppm

  • Maintain a stabilizer level of at least 60ppm-80ppm to hold chlorine in the water longer & reduce the demand on the salt cell
