A nylon or rubber brush is the correct choice for scrubbing the sides of a soft-sided above-ground pool. A large pool brush makes quick work of the job, but you may need a smaller brush to clean corners. Once the particles have been removed from the sides of the pool, turn your filter back on and agitate the water.
Brush Your Pool
Brushing down the pool walls is going to be the first step you need to take, loosening and removing algae that's clinging to them. Depending on your pool's finish you may need a soft bristle brush (for fiberglass or vinyl liner pools), or a steel bristle brush (for concrete and plaster finishes).
Green Algae
They can also dislodge themselves from the wall and float on the surface of the water. To remove green algae, all you need is a scrubbing brush and some household borax solution. You have to apply borax to the algae-infested surfaces and scrub them really hard with the brush.
Depending on the type of surface in your pool, you can use a brush to scrap it clean with or without water in it. If the pool has a soft vinyl liner, you will use a rubber or nylon brush to keep it clean. If the pool has a concrete floor and walls, a stiff and course brush will do the trick.
Mix the baking soda and Borax, then add just enough bleach to form a thick paste. Apply the paste to your pool brush for extra algae-cleaning power. The baking soda and Borax lift stains and loosen the algae's roots from the pool's walls and bottom. The chlorine bleach kills algae and bacteria in the water.
Grab a brush and some baking soda. Bicarbonate, the active ingredient in baking soda, is an effective spot treatment to help kill the algae and loosen it from the wall. Make sure you really get every last particle free; black algae has particularly long and stubborn roots which makes it a persistent strand.
Pool algae can be caused by poor filtration, out-of-balance water, low or inconsistent chlorine levels, or poor water circulation. Green, dark green, yellowish green and blue-green algae are the most common.
Start at the shallow end and then work your way to the deep end of the pool. Once you've vacuumed it once, you'll need to grab a brush and scrub away at your pool's floor. Then vacuum it again. Repeat this until the bottom of your pool looks clean.
Sand filters often do not filter 100% of algae. The more times a pool is shocked once you have algae, the smaller the particles get. Ideally, turning off the pump for a day will drop all the algae to the bottom and then you vacuum to waste.
Although DE powder is used for filter grids, it can be added to sand filters. When the powder is added to the sand, the sharp edges of the DE powder enhance the filtering process of the sand by capturing tiny dirt particles during the filtering process.
When do I need to replace my sand? On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.
Too much sand and your filter will likely not run correctly or may break when reassembling. Too little sand and you will have cloudy water no matter how much your filter runs.
Baking Soda and Green, Blue, or Yellow Algae
You'll need to use an algaecide to kill the algae and superchlorinate your pool to clear the water. After this treatment, test your pH and alkalinity and add baking soda to raise alkalinity to at least 100 ppm and pH to between 7.2 and 7.8.
But is it safe to swim in a pool with algae? Whether mild or severe, it isn't recommended. Significant amounts of swimming pool algae welcome a breeding ground of harmful bacteria that feed on algae. These bacteria pose health risks to swimmers, most commonly resulting in a skin rash.
Use a mixture of water and white vinegar to spray down the area and kill the algae. Rinse the surface alga off the concrete with a water hose. Next, pour white vinegar directly on the surface and scrub using a brush.
STEP 1: Attach vacuum head to the pole. STEP 2: Attach vacuum hose to the vacuum head on the end of the pole. STEP 3: Submerge vacuum hose and head into the pool. STEP 4: Push air out of the hose by feeding it down through the water, or just simply hold one end over a pool return while filtering to fill it with water.
Insert the open end of the hose into the vacuum plate (also known as a skimmer plate or skimmer disk), and place the plate into your pool wall skimmer, directly atop the suction vent. This will initiate the vacuuming process. Slowly sway the vacuum head in straight lines along the bottom of your pool until it's clean.
Insert the telescoping handle into the handle hole on the garden hose pool vacuum. Insert the end of your garden hose into the hose valve on the vacuum. Turn on the water to the garden hose and lower the vacuum into the pool.
Changing the pool filter sand is a bit of a pain, especially in the back region, but a bag of pool filter sand costs around R90 at your local Builders Warehouse, and you should only need two bags for most pool filters.
Deep Chemical Cleaning
Turn the valve to “filter” and remove the pump's strainer lid. Pour sand filter cleaner into the strainer basket and replace the lid. Turn the pump off and leave it off for at least 8 hours. Backwash the filter for 3-5 minutes again to remove dirt, debris, and the cleaner.
Can You Backwash Too Much? If you backwash your pool too much i.e. time duration and/or close frequency then yes you can cause a lot of problems. Some problems that can arise from backwashing your sand pool filter too much are: Loss of water – 500+ litres of water can be lost in each backwashing cycle.
