Algae can form in a swimming pool if the water is not properly maintained. It relies on sunlight and the oxygen in the pool water for photosynthesis and it can quickly spread across the lining of an afflicted swimming pool. In addition to negatively affecting your pool's appearance, if algae is able to grow in the water other organisms could be forming in the pool as well. Even though black algae is simple to spot, removing if from a pool with a vinyl liner requires care and diligence.
Scrub the vinyl liner with a nylon brush to help dislodge any algae that has attached to the liner. Don't use a metal brush, which could tear the vinyl material in the liner.
Shock the pool water. Pool shock is a hyper-chlorinated solution that helps kill off algae and other organisms in the water. Follow all instructions on the bottle in regard to how to add the shock to the water and how much to use. Brush the pool again once the shock has been added.
Apply a polymer algaecide to the water as well, which will target the black algae specifically. Continue brushing the pool at least twice a day until all the algae is gone.
Run the pool filter continuously until all the algae is removed.
Flush water through your filter system on a regular basis. You know that it's time to have your filter cleaned when the pool water pressure doesn't drop down to it's normal range.
Rinse loose dirt and debris from the filter. Rinse gently with water because spraying the filter too hard can lead to further clogs.
Soak the pool filter overnight in an alkaline based cleansing solution. Rinse the filter with water to remove any chemicals before you place the filter in the pool again.
Obtain a bottle of liquid chlorine to pour into the pool. Tip the container of chlorine over in front of a main jet and allow a few gallons to pour out.
Walk away from the pool for 15 minutes. If the algae looks considerably lighter when you return, you've added enough chlorine. If the algae is still quite visible, add a few more gallons of chlorine.
Keep the pool filter running during this process. The filter must run until the water clears. These methods should result in both a clean pool and a clean pool filter.
Brush the algae thoroughly with a stiff pool brush to “break open” the slimy layer. Failing to do this may prevent the treatment from working as chemicals won't be able to penetrate the algae as well.
Shut off the pool pump.
Pour algaecide over the black algae according to the directions on the bottle and leave it overnight.
The next day, brush away and discard all the dead algae spots.
Repeat the process if you continue to see some black algae spots.
Restart the pool pump for circulation and adjust the pool's salt levels.
Make sure you maintain proper salt water chlorination levels as it helps kill bacteria and prevent black algae from growing back.
Check the water level of the pool to make sure it is up to a normal operating level.
Filter the dead algae out of the pool's filtration system by back-washing it. Turn the pool pump off and turn the multi-port valve in the backwash position. Open the pool's "backwash gate valve," if the pool is equipped with one.
Turn the pool pump back on and let it run for about two minutes. Turn the pool pump off and reset the multi-port valve to the "rinse" or "filter" setting.
Turn the pool pump on and let it run for approximately one minute. Shut the pump off and repeat all of the steps above one more time.
Set the multi-port valve back in the filter position and shut the backwash gate valve, if the pool pump has one. Turn on the pump and recheck the level of water in the pool and, if necessary, add more water.
Ammonia and Algae
The three most common types of algae are green (floats on the surface of the water), mustard (slimy yellow film on walls of pool) and black (clumps on tile grout and pool steps). All three require different treatments, so identify them based on these characteristics first. Green algae is the easiest to treat with chemicals. Proper chlorine balance in a pool rectifies this situation. "Superclorinate" the water at night with a 10 to 20 ppm (parts per million) ratio. The filter should continue running to catch dead and dying algae and you should scrape the walls of the pool to knock any algae loose. Ammonia is used in the next stage, where you place an algicide with ammonia as an ingredient in the water. This prevents green algae from returning after the superclorination has killed the algae. Mustard algae is harder to fight, and will not be as susceptible to chemical treatment. Do the same as with green algae, but also vacuum the walls prior to adding the ammonia-based algicide. Black algae is the most difficult, and will require an ammonia-based algicide after it is rid from the pool, but ridding it from the pool will most likely mean draining the pool and scrubbing the algae off.
Empty the water out of the fountain at least every other day.
Remove tree, flower or leaf debris daily from the fountain. Organic material creates the perfect environment for algae to form.
Scrub the sides of the fountain with a stiff brush after emptying, rinse and then refill the fountain. Water quality should be perfect and clear until the next water change. Water becomes stagnant if left to sit more than a day or two.
Remove and rinse clean the fountain pump and tubing with every other water change to remove algae residue. Soak the tubing and pump parts for 15 minutes in 2 cups of white vinegar mixed with 1 gallon of water.
Add 1/2 cup of white vinegar to the fountain to discourage algae buildup if water replacement doesn't clear the algae problem. Perform daily water changes and soak the pump and tubing in white vinegar more frequently to kill residual algae.
Write down the total gallons of water in the pool -- this number can be acquired from the contractors who built the pool or in the user's manual. This number is necessary to purchase the correct amount of 2-lb. bags of quaternary ammonia.
Multiple every 10,000 gallons of water in the pool by 2 -- the number of pounds per bag of quaternary ammonia. Write down the total number of pounds you'll need.
Purchase bags of quaternary ammonia that equal the total pounds needed.
Put on a pair of work gloves. Pour a bag of the quaternary ammonia into a bucket. Add a quart of water into the bucket. Stir the mixture with a wooden paint stir for about a minute.
Stand at one end of the pool. Pour the mixture from the bucket into the pool as you walk around the perimeter. Continue doing this until the bucket is empty.
Refill the bucket in the same manner as in Step No. 4 and resume the procedure from the point where you stopped. Continue until all of the bags of the quaternary ammonia have been emptied into the swimming pool.
Return to the pool after 24 hours have passed. Vacuum the dead algae from the surface of the pool using a pool vacuum cleaner.
Attach a brush head to a pool pole and scrub algae-coated surfaces of the Intex pool.
Attach a pool vacuum head to the pool pole. Place the vacuum's hose on the connection on top of the vacuum head.
Plug the free end of the vacuum's hose into the hole at the bottom of the pool skimmer. Turn on the pool pump to begin water flow.
Maneuver the vacuum head over the pool floor with the pole. Move slowly to allow the vacuum to suck up and remove the algae on the bottom.
Shut off the pump after the suction of the vacuum weakens. Unscrew the lid of the pool filter. Remove the filter cartridge and spray it with water to remove algae clinging to the filter.
Place the cartridge into the filter and screw the lid back into place. Continue vacuuming the algae off the pool bottom. Repeat the filter cleaning process if suction weakens.
Measure the appropriate amount of Yellow Treat for the pool. Use 5 oz. of Yellow Treat for every 10,000 gallons of water. For instance, if it's a 25,000 gallon pool, it takes 12.5 oz. of Yellow Treat to kill the algae.
Pour the Yellow Treat into the pool, directly over the drain. Pouring over the drain will cause the Yellow Treat to flow through the pump and circulate in the water more quickly.
Turn on the pump and let it run for at least an hour to allow the Yellow Treat to incorporate itself throughout the water.
Repeat the process again if the yellow algae return. Shocking the pool may be necessary if the first Yellow Treat application is unsuccessful.
Understand how to shock your pool water. This process should always be done at night. Dissolve each dose of shock in a bucket of clean water, then add to the water one at a time.
Double shock your pool water. This can help get rid of algae in the beginning stages just as your water is turning green. Shock can be purchased from a pool supply store or home improvement center. Normally, you need 1 lb. of shock for every 10,000 gallons of water, so to double shock the water, use twice that amount. You may need to shock a third and fourth time.
Add flocculant to the water if shocking doesn't work after a day or two. This chemical, also available at pool supply stores, will cause the algae to drop to the bottom of the pool.
Use a swimming pool vacuum cleaner to clean up the algae on the bottom. This could take a while but will get rid of the existing algae.
Check the pool's filter system. A clogged filter or a filter not run consistently can allow algae to build up in a swimming pool. Make sure the filter system is turned on so the water circulates and is passed through the filter.
Empty or unclog the drain trap of the filter. A buildup of debris like leaves and dead insects provides a place for algae and bacteria to grow and feed on. This buildup can stop the filter system from cleaning the pool properly.
Run a pool vacuum cleaner once a week to suction brown algae spots off the bottom and sides of the swimming pool. Pool vacuums help to keep the water and interior of the pool clean.
Add a chlorine shock to the pool to help clean the water and kill any existing algae. Follow all directions on the shock to add the right amount to your pool. Different sized pools need different amounts of chlorine.
Create a weekly cleaning schedule for the swimming pool to treat any existing brown algae spots and keep them from returning. Vacuum the pool once a week and add chlorine or shock as needed to keep the water clean.
Stuff the barley straw into the mesh bag and tie it shut using the rubber band.
Place the bag of straw either in the center of the pond or in the area with the most water flow. As the barley decomposes, it will release a chemical which eliminates algae.
Spread the water lilies over the pond, making sure to cover about two-thirds of the surface. You can also use duckweed or water hyacinth or a combination of all three. The plants will block sunlight and utilize nutrients that would otherwise be used by the algae to multiply.
Brush the sides and bottom of the pool to disrupt and remove the algae. Attach a long handle to the brush to reach the center of the pool.
Check the pH in the pool using a test strip. Raise or lower the pH until is reaches a level as close to 7.2 as possible. This is the lower end of the suggest pH.
Use an algaecide to treat the algae in the pool. Follow the manufacturer's recommended application for your pool size.
Add the shock to your pool after preparing the water by stabilizing the pH and treating the algae with algaecide. Use two pounds of shock per 10,000 gallons of water. For non-chlorine shock treatments, allow the pool filter to run for about 15 minutes before swimming.
Vacuum the pool to remove any debris or remaining algae. If necessary, brush the sides again. Use shock after a heavy rain or once a week to prevent future algae formation. Follow the manufactures suggestion when adding shock for water maintenance and algae prevention.
Assemble the pool vacuum if you haven't used it before. Attach the vacuum head to the hose, then connect the hose to the vacuum pump
Sink the vacuum into the pool slowly before turning on the pump. This helps retain the proper suction that is necessary for the vacuum to work. Lean the vacuum against the pool wall.
Put on an old swimsuit and a pair of gloves. Skim the top of the pool with a pool skimmer; sometimes algae is present on the top of the pool, which prevents you from seeing the pool bottom. Clear the algae off the pool surface so you can see into the water. Discard the algae and other contaminants far away from the pool, or in a trash can.
Sweep the pool bottom and the sides of the pool walls with a long-handled brush to loosen any algae and contaminants that are firmly attached to the pool floor or stuck to the walls. Allow the water to settle for several minutes to a half-hour.
Turn on the pool vacuum. Vacuum up the algae and debris that have settled on the bottom of the pool. Work slowly and use long, sweeping motions to prevent the algae from becoming stirred up. If algae remains, brush the walls and floor again and repeat the vacuuming process.
Create a shallow, still pond of water warmed by the sun to 65 to 80 degrees Fahrenheit. This will produce the best algae growth.
Remove trees or other vegetation, which block sunlight from reaching the pond. Keep the water warm by sunlight, which is a key element for raising blue and green algae.
Add 1 lb. of raw or composted manure per 1,000 cubic feet of water to stimulate algae growth. Spread the manure over the top of the water and allow it to settle to the bottom.
Harvest the algae using a rake. Add an additional 1/2 lb. of manure that is high in nitrogen and phosphorous per 1,000 cubic feet of water to maintain algae growth over a prolonged period.
Algae act as food for some pond fish and for microorganisms that fish and other animals consume. It plays an important role in a pond's food chain.
Algae absorb nutrients like nitrates, ammonia and phosphorus. Too much of these elements in pond water can be detrimental to plants and animals and the overall health of the pond.
Algae provide shade for underwater plants and animals that need it, especially during the hottest parts of the day and year.
Oxygen Production and Use
Algae produce oxygen during the daytime, which in turn provides oxygen for fish and other underwater organisms, microorganisms and plants. On the flip side, algae uses oxygen at night, and too much algae can deplete the water's oxygen.
Hair algae provides shelter for fish to spawn and lay their eggs.
Stand at the edge of the pond and reach your rake out toward the closest string of algae. Hook the algae onto the rake tines, then drag the algae toward the edge of the pond.
Lift the rake out of the pond along with the algae. Then pick the algae off the rake and dispose of it in a garbage bag.
Target all long strings of algae with your rake.
Work over the surface of the pond with a skimmer, such as the ones used to skim debris from swimming pools. Life out any small pieces of moss or algae you were unable to capture with the rake by using the skimmer.
