Problem Solvers

Here are some problem solvers that should help you get swimming again sooner. (Please consult your pool professional for the best advice and support that are specific to your pool's problems.)

I have blackspot algae all over my pool

This is a very common problem particularly with pebblecrete pools running on salt chlorination. The following treatment will help in most cases. If the problem is extreme and the pool surface is white plaster, tile or natural pebblecrete ONLY granular blackspot remover may be used. DO NOT use Granular Blackspot if the pool surface is coloured as bleaching will result.

  1. Adjust the pH of the pool to 7.4-7.6
  2. Using a stainless steel brush vigorously brush the blackspot so that the “wax” coating protecting the root system can be penetrated by the algicide.
  3. With the pump and filter running add Focus Blackspot and Longlife Algicide following the label directions to ensure the correct dosage for your pool.
  4. Allow the pool to circulate for a couple of hours after application.
  5. The blackspot algae will turn grey and start to drop down to the bottom of the pool. Vacuum visible algae to waste and resume normal filtration.
  6. Repeat the treatment if necessary.

My kids are complaining that their eyes are stinging and the pool really smells of chlorine.

Over time your swimming pool water becomes dull and irritating as it will accumulate a build-up of waste products. The waste products come from rain, insects, hairspray, suntan lotion, make-up, urine and other wastes introduced by either the environment or swimmers. These waste products “tie up” your chlorine making it inefficient and causing a pungent “chlorine” odour.

  1. Adjust pH of the pool water to between 7.4 to 7.6

  2. With the pump and filter running add one bag of Shock and Clear (per 50,000 litres of pool water)

  3. Run the filter for at least one hour.

  4. If the problem still persists contact your nearest Focus Products Authorised Dealer and ask for a Free and Total Chlorine test. This will determine if more applications are needed.

My pool walls and floor are green and slimy.

The first question to ask is whether the growth can be removed through brushing as this will confirm whether or not the discolouration is caused by an algae growth. If the answer is yes then apply the following treatment:

  1. Adjust the pH of the pool water to 7.4 to 7.6
  2. Brush the walls and floor of the pool to stir up the algae
  3. Treat the pool with at least one bag of Shock and Clear (per 50,000 litres) by pouring through the skimmer box with the pump and filter in operation
  4. Pour 2 litres of Focus Algicide 20% around the edge of the pool.
  5. Follow the algicide treatment with either 200ml of Waterpolish or a sachet of Ultrasheen.
  6. Run the filter continuously observing the pressure gauge. Backwash or clean the filter if the pressure exceeds Manufacturers recommendations.

 

My pool water is cloudy

The first thing to check is that the filtration system is working effectively and does not need chemically cleaning. If the filtration is working effectively the following should be checked.

  1. Check the pH of the water is between 7.4 to 7.6. If the pH is high this can cause water to be cloudy. Adjust pH accordingly.
  2. Check that the pool has maintained a consistent chlorine reading over the past few days. Reduced chlorine levels can also cause cloudy water. If the chlorine level has not been consistent then apply a bag of Shock and Clear (per 50,000 litres) by pouring through the skimmer with the pump and filter in operation. If the chlorine level does not hold after the first treatment then repeat the process until the chlorine residual is maintained.
  3. If the chlorine and pH levels are OK then the cloudy water is probably due to suspended particles in the water. Add 200ml of Waterpolish to 50,000 litres of pool water to restore and maintain sparkling water. Run filter for at least 8 hours. Backwash the filter if pressure reaches the maximum recommended by the Manufacture

I cannot keep chlorine in the water

  1. The first thing to check is that the pH is in range and that you have Stabiliser in the water. If not, adjust the pH and add stabiliser.
  2. If you have added large amounts of chlorine to the pool and are still unable to get a chlorine reading it is possible that the chlorine is “bleaching” out your test tablets. Dilute the sample with tap water (4 parts tap water and 1 part pool water) and retest. Remember if you get a chlorine reading to multiply the result by 5 to be accurate.
  3. If the test is not being “bleached” out then the water has an organic demand. This will require double or even three times the normal shock dose of chlorine to eliminate.
  4. Add 2 kgs of Focus Stabilised Chlorine (per 50,000 litres of pool water) to the pool with the pump and filter in operation.
  5. Run the filter for at least six hours.
  6. Retest and repeat the treatment with a kilo of stabilised chlorine at a time until the chlorine residual is maintained.
