What's the right water balance for pools?

The ideal chemical water balance in pools means maintaining pH, alkalinity, chlorine, and stabiliser within an approximate range. The range displayed below is only a rough guideline, and CAUTION MUST BE TAKEN when reading this guideline as the correct balance for your pool may differ depending on a number of factors including (but not limited to) whether it is a quartzon pool, it has a heat exchanger, and the particular type of pool and set-up.  Please always refer to the manufactures manual and warranty for exact details. If you have any doubts, please feel free to call us for further advice.

pH: 7.0 – 7.4 Fibreglass; 7.4 - 7.8 Plaster, Vinyl, Painted
The pH scale runs from 0 to 14 and is a measure of the acidity or alkalinity of a solution. You will never get the best out of your pool unless the pH is correct.

Chlorine 1 – 2 ppm
Also known as free chlorine. It is formed when sodium hypochlorite, calcium hypochlorite, dichlor, or trichlor are mixed with water and dissociate. This is the main pool water disinfectant.

Free chlorine acts as a sanitizer killing potentially harmful bacteria and micro-organisms.

Useful amounts of free chlorine can only be obtained if the pH is within certain limits, or if the stabiliser level is not too high.

Alkalinity 40 - 80 ppm Fibreglass; 80 – 120 ppm Vinyl, Painted;  150 - 200 ppm Plaster
Closely related to pH, but the two must not be confused. Total alkalinity is a measure of the amount of alkaline materials in the water. This alkalinity will usually be present as bicarbonates.

The relevance to pH is that the amount of alkalinity in the water will determine how easy it is for changes in pH to occur.

Stabiliser 30 – 50 ppm
The chemical name is cyanuric acid. Be reassured - cyanuric acid is a polymerised urea; it has nothing whatever to do with cyanide or isocyanates. Although it is an organic acid it will not affect the pH of the water when added.

It can be obtained as a granular product in its own right (Pool-Treat Sunscreen). It is also formed when the stabilised chlorines (dichlor or trichlor) are dissolved in water - they dissociate into free chlorine and cyanuric acid (stabiliser).

Low levels of stabiliser are beneficial because they prevent wastage of free chlorine by the ulta violet waves in sunlight. High levels are a disadvantage because they inhibit free chlorine killing micro-organisms.

How to treat a green pool? Shock dosing at the beginning of the season?

During the winter months with lots of rain and wind blown dust and dirt a lot of nutrients have built up in your pool. In spring algae will quickly grow making advantage of your winter store of nutrients and increased light levels.

The answer is to super shock dose the pool with chlorine. With this super shock of chlorine it will break down and destroy the accumulated nutrients in the pool and thus free if from the threat of an algae bloom.

Even if you are a bit late and algae has started or even taken over your pool a large shock dose of chlorine is your quickest and easiest remedy.

If the pool bottom is not visible the addition of a flocculent like Pool treat Pool Floc in conjunction with a Super Shock dose of chlorine is your best answer.

Get that pH checked before the shock dose is added. The chlorine will be a lot more effective if the pH is in the 7 to 7.5 range. When algae metabolises in the pool they tend to increase the pH and can increase the pH range to 8.5 to 9.0, which inhibits the effectiveness of chlorine - cunning little critters.

Recommended Super Shock doses "The Spring Start Up"

Clear to slightly cloudy pool - Has not been treated for a while and needs a wake-up call for summer.
- Super shock dose at 6 times the daily recommend dose for your pool size.

Green pool - However can still see the bottom.
- Super shock dose "PLUS" at 8 times the daily recommended dose for your pool size.

Green pool - Thick with algae and cannot see the bottom even at the shallow end.
- Super shock dose "EXTRA" at 10 to 12 times the daily recommended dose for your pool size.

How much Chlorine should I add to my pool? Chlorine treated pools and the dose cycle

For all chlorine treated pools to achieve a healthy and hygienic pool you are required to maintain a minimum of 1 ppm of chlorine and up to a maximum of 5 ppm of chlorine in the pool water at all times.

This can be achieved by a variety of types of chlorine (different chlorine options), however maintaining chlorine levels, combined with sufficient filtration will provide a healthy and trouble free pool.

Just these two aspects of pool treatment are the most important - Sufficient chlorine and sufficient filtration.

All packs of chlorine products have a recommended dose rate, however this is just an indication of how much an average pool might require.  A variation in the amount of usage the pool gets and a host of other factors influence the amount of chlorine a pool requires. So how do we know? It is simple; we test the pool for residual or free chlorine. That is, the chlorine that is unused and still remaining in the pool.

So when we add the chlorine, preferably each night when all the swimming is completed, the chlorine level might increase to 5 ppm.  Over the night period and the next day the chlorine works on the impurities in the pool water, cleaning the pool water and is progressively used up.

So if we test the pool water just before our next dose of chlorine, we can evaluate if we are adding enough chlorine to last the distance.  We want to achieve at least 1 ppm of chlorine before we replenish the supply back up to that 4 to 5 ppm region.  This is referred to as the dose cycle and is preferable 24 hours, however in low usage pools this can be extended out to a number of days.  The same principle of testing just before you dose still applies. That is, checking if we have maintained that all important reserve of 1 ppm chlorine.

If the chlorine level drops to zero then that is when the problems start with algae getting a foot hold and cloudiness of the pool water. So avoid this if you can.

Based on the dose cycle if you test result is:

Chlorine level

Pool Treatment

4 to 5 ppm

(or higher)

No additional treatment required. A high level of chlorine may irritate the eyes (if a lot of contact) and may also bleach sensitive swimming apparel.

2 to 3 ppm

OK level and is fine to swim in. However the amount of chlorine product you are adding daily can be decreased.  Decrease by one third.

0.5 to 1.5 ppm

Ideal level of chlorine. Continue with the same amount of chlorine product.

0 ppm

Problem time.  Increase chlorine dosing otherwise problems will start.  Double the previous day dose of chlorine product.

Is there an easy way to treat my pool? Easy pool treatment option

STEP 1:

Test water and get the chemical balance right.
• If you get the water right from the start it makes further treatment much easier, and in the end allows you to use fewer chemicals in your maintenance program.

STEP 2:

Add Pool-Treat Maxi-Tabs to the water based on size of pool.
• Maxi tabs are a stabilised form of chlorine, this helps prevent chlorine from being affected by ultra-violet rays of the sun so it stays in the water longer. They can be dispensed in the skimmer or with automatic chlorinator.

STEP 3:

Shock-Dose the Pool Weekly with Pool-Treat Granular or Liquid.
• This shock-dose helps maintain control over foreign contaminants in the water, which may come from debris such as leaves or even make-up and hair products.

STEP 4:

Add 500gms of Conditioner for every 1kg of maxi-tabs used.
• The conditioner helps stabilise the pH in the water, 500grams per kilo of tablets is the ideal requirement to maintain an ideal pH and alkalinity level.

Note:Consult the pack or your dealer for recommendations on quantities required for your pool and for any other advice required.
