The first step is to ascertain what is causing the stain. Staining can sometimes be caused by incorrect water balance. Check your water balance and adjust if necessary to the correct levels. Stains can also be caused by metal contamination and tannins from leaves. The following is a checklist to assist in determining the likely source of the problem:
The longer a stain is present in a pool, the harder it is to eliminate. Contact your nearest Focus Products Authorised Dealer for information on the treatment and prevention of stains.
Blonde hair particularly can experience this problem. It is generally caused by incorrect water balance, excess copper or high chlorine levels. Pay particular care to your water balance to eliminate the likelihood of it occurring.
It can be removed from the hair by any of the following methods:
Pools can get calcium levels that build up over a period of time, particularly those pools utilising Calcium Hypochlorite, which can cause hard scale to form on the surface of the pool. New pools particularly can have a scaling issue as they “adjust”. In areas of high water hardness the problem is unavoidable. To prevent scale from forming Aquashield 3 should be added every three months.
This will inhibit calcium scale and assist with the cleaning of the salt chlorinator cell. To remove deposits that have already formed it will be necessary to conduct a treatment involving Hydrochloric Acid and Aquashield 3. Contact your nearest Focus Products Authorised Dealer for assistance.
This is dependent on which State you live in (water balance is affected by temperature), where the pool is situated (shade or no shade), the bather load of the pool, the size of the pool, the sanitation process you are using and other factors. As a rough guide in tropical climates during the warmest months of the year the recommendation would be a minimum of 8 hours up to 12 hours separated into 2 cycles.
This can be reduced back to 2-3 hours during the cold months or non-swimming times. Inadequate filtration time is the primary cause of cloudy, green or unsanitary water. Check with your nearest Focus Products Authorised Dealer for the correct advice on running times for your pool.
