Shocking Your Pool Water

How To Remove Algae from a Swimming Pool

The term shocking refers to raising the levels of free chlorine, or chlorine that hasnt yet mixed with the water, by adding chlorine or other chemicals to your pool water.

Depending on how often your pool gets used, shock your pool once every week or two during the peak swimming season. Chlorine works best at a pH level between 7.2-7.8. Acidic water is harmful to both swimmers and the pool itself.

With a pH above 8.0, chlorine quickly loses potency. The goal of shocking your pool is to raise the free chlorine level to eliminate contaminants, kill algae, and for clearing a cloudy pool.

Note that pool shocking chemicals that get rid of brown algae in the pool are different from clarifiers and flocculants. Water clarifier products consolidate particles in the water into small clumps that the pool filter is better able to catch.

Flocculant products coagulate debris into large clumps that sink to the pools bottom for easier manual removal.

Chlorine bleach works as a DIY alternative to name-brand pool shock chemicals. The active ingredient in swimming pool shock and chlorine bleach is sodium hypochlorite.

Pool shock contains about twice the concentration of household bleach. Clorox recommends using a half-cup of bleach per thousand gallons of water. Its best to apply the bleach treatment at night, as sunlight quickly decreases its potency.

Get Ph And Alkalinity Back To Normal Levels

Ascorbic acid is strong and will definitely bring down pH and TA levels. If the pH and TA are not way out of balance, you can use 20 Mule Team Borax to raise the pH without affecting TA and an alkalinity increaser to bring the TA up to recommended levels when it gets low. Add these chemicals slowly while testing until they get to recommended levels since you dont want pH or TA to get out of balance.

Remember that pH should be maintained between 7.4 and 7.6 to avoid metal staining. I prefer using LaMotte ColorQ Pro 7 digital pool water test kit since it is very accurate and fast in taking all chemical readings. If you get your pH and TA out of balance by mistake or they get troublesome to balance, here is more about how you can balance pH and TA.

Clean The Pool Filters

When the debris and dead algae have been brushed off the walls of the swimming pool, the filter will have lots of dirt to filter from the water. At this stage, you need to clean the filters to allow them work again. If your pool uses sand filters, you need to backwash them. Cartridge filters are just to be cleaned.

The procedure to backwash your sand filters is as follows:

  • Slide the push valve or turn the multiport valve handle to the backwash option.
  • Turn on the pump and run it until the water is clear.
  • Shut off the pump then move the valve back to the filter option and then turn the filter back on.

Your sand filter will be ready to use again.

    Lower The Ph Level To 72

    How To Get Algae Stains Off Pool Walls

    Lower your pH level to 7.2 using muriatic acid if its higher than that. This is necessary since high pH levels may need a lot of ascorbic acids to clear metal stains and may also contribute to more metal staining, which is what you need to get rid of. I prefer muriatic acid since pH minus will not lower the total alkalinity and high TA might cause pH to scale high if clearing stains takes longer.

    Using a pressure washer, apply the detergent inside the tank and follow manufacturer directions when mixing it with water. Wash the side walls first. Do one small section at a time, starting from the top and working your way side to side and down. Doing small sections ensures that you wash the walls thoroughly and helps avoid missing any spots. You may need to allow the detergent to set on the side for 5 to 15 minutes to work the scum off the pool walls. Keep the area damp by occasionally applying water to the sides. Switch to a softer or more delicate low pressure wash and pure water in the tank. Wash the walls removing all of the detergent. Again start at the top and work your way down.

    Last And Most Accessible Solution

    While you are on the swimming pool, carry a towel or microfiber brush with you and scrub that pools wall area. You can do it a minimum twice a week. Regular base cleaning provides a fruitful result to remove all kinds of stain from the pool. Removing algae stain, you should figure out the stain category of your pool. And by maintaining all the above steps, you can solve the algae stain problems accurately.

    Get Algae Out Of Pool Without A Vacuum

    Algae Stains on Pool Plaster

    If you dont have a vacuum for your pool, dont worry. It takes a little extra effort, but removing algae from pool bottom without a vacuum is possible.

    If your pool has a filtration system, the filter should be able to take care of a swimming pool with algae after scrubbing it off the sides and bottom of the pool.

    After scrubbing with your pool brush, agitate the water with your hands or a garden hose with a pressure attachment to lift algae on bottom of pool, so it gets picked up by the filter.

    Large clumps of algae may clog your pool filter, so it might be necessary to rinse it part-way through cleaning up your algae bloom.

    If your pool doesnt have a filtration system, use a pool brush or regular broom to gather the sediment and dead algae on bottom of pool to one corner.

    Its critical to move slowly so the debris doesnt spread too far in the water. Once youve made a pile in a corner, use a skimmer, net, or dustpan to collect the algae and sediment and gently lift it out of the pool.

    If you discover your pool has gone from crystal clear to murky and green, dont panic. While prevention is the best cure for an algae problem, eliminating an algae bloom is usually straightforward.

    In addition to your regular pool cleaner products, youll need pool shock, flocculant or clarifier, an abrasive brush that wont damage your pools surface, and a pool vacuum or skimmer. With a bit of effort, youll have your swimming pool looking like new in no time.

    Keep The Water Circulating

    Algae will grow faster in stagnant water since the spores need to stick to a surface to grow. If you circulate water in the pool, itll not give the algae time and surfaces to grow on. Running the pools pump will do the trick and its something that ought to be done daily. Running it for at least 10 hours each day is the recommended time.

    Brush Your Pool Walls And Floor

    Scrubbing the algae off your pool walls lets your sanitizer get deeper into the remaining algae. It also stirs up the sediment youve brushed off so it can be killed and filtered out.

    Using a stiff pool brush on a pole, brush the walls and floor of your pool. Pay special attention to corners and shady areas where algae is usually worst. As you go, your water will become cloudy, obstructing your view, so get those tough spots first.

    Balance The Pools Chemicals

    When the pools pH is high and the pool is thus basic , algae will thrive in it. You should thus keep the pH of the pool about 7.4. Besides this, you need to maintain the chlorine level between 2 and 4 ppm besides many other chemical balances. You should have a pool-testing kit to help you find the right chemical balance for your pool.

    Add Metal Sequestrate In Your Pool Water

    How To Get Algae Stains Off Pool Walls

    Metal sequestrate should be the last option to use in a pool because it works differently from metal removers like Metal Magic and Orendas SC-100. Metal sequestrate does not remove metals in your pool water. Still, it naturally binds to the metals, holding metal particles together in your water so that they don’t come out of the solution to react with chlorine when added to your water or when pH levels get too high.

    Ideally, regular doses of sequestrants will prevent metal staining when chlorine is added into the water and slowly break down. Therefore, they should be introduced regularly in your pool water to maintain the right level to keep stains away.

    The most effective sequestrants are derived from phosphoric acid, and the best in the market today is Pool Mate Metal Out. This product helps prevent discoloration of pool water from iron, silver, manganese, copper, and other metals and minerals that may be present in the water supply.

    Pool Mate Metal Out is an excellent general-purpose sequestrant that helps protect plumbing and pool walls from rust, stain, and scale. It should be used for pool openings and closings and throughout the season. For best results, add 1 quart per 10,000 gallons weekly, and you will never have metal stains in your pool.

    How Do I Remove Algae Stains

    Its worth checking for other kinds of algae frequently while using the pool. Yellow or mustard algae can grow in a shaded corner of the pool and is resistant to normal chlorine levels, explains River Pools. Black spot algae is even tougher to kill and can cause permanent damage to the underwater surfaces of your pool. It can be hard to spot and is resistant to chlorine. You may also see pink slime, which is caused by bacteria rather than algae and often grows inside polyvinyl chloride, or PVC, piping.

    Your first step in getting rid of nasty algae is to correct and clean the pool. First, correct it by doing your testing to determine the pH, level of chlorine, and stabilizer or other important chemicals. What you test depends on the chemical system your pool uses you should know what components are important and how they work together so that you can test appropriately.

    Testing The Pool Wateris It Metal Staining Or Algae

    Before taking any action to undergo treatment for metal stains, you need to be certain of its metal staining. Green or black stains might indicate metal stains, but they may also occur due to green or black algae. Do the vitamin C test by using ascorbic acid to determine whether it’s metal staining or not:

  • Hold a vitamin C tablet against a potion of the stain for about 30 seconds.
  • If the stain vanishes or lightens, then it is a metal stain and not algae.
