Use 1 part bleach to 20 parts water. Soak your rag in the solution and wipe the pool clean. Avoid using paper towels when using a bleach solution to clean the pool. They won't hold up very well and will just create a bigger mess for you to clean up.
Before using the bleach or cleaning solution, you can scrub the pool down with soapy water to lift any grime or slimy residue on the pool surface. If the pool wasn't really dirty to begin with, you may be fine just cleaning it this way with soapy water.
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.
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 water turns green because of algae in the water. Algae can grow rapidly, particularly when it's warm like Summer, which is why it can surprise you overnight. This generally comes down to an imbalance or lack of chlorine in the water.
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.
All you need to do is bypass the filter and pool vacuum for algae to the waste. However, this can only work if you have a multiport system or a waste line system in your cartridge filter. Vacuum the pool to waste after you have set up the waste, and the debris and algae will get out of your pool.
Use chlorine as your go-to algae killer.
When your pool water is green or contains visible algae clumps, your pool does not have enough chlorine. "Shocking" the pool with a large dose of chlorine is the most effective way to kill the existing algae and bring your pool back to sanitary conditions.
Causes of Algae in Pools
In short, algae are always in the pool, and can bloom into a visible colony when conditions are right: Poor water circulation; low flow or dead spots in the pool. Poor water balance; pH, Alkalinity, Calcium and Cyanuric levels. Poor water sanitation; low or inconsistent chlorine levels.
If you don't have a drain plug in your kiddie pool, but you have a nearby hillside, you could use a garden hose to siphon most of the water out, to a point where you can flip it over to empty fully. An easier method would be to use one of our small submersible pumps.
Chlorine In Small Inflatable Pools
For small inflatable pools that you don't want to empty and refill so often, you can add a small amount of bleach to the water to sanitize it. Add about a 1/4 tsp for every 10 gallons of water, or for medium sized inflatable pools, add 2 1/2 tsp for every 100 gallons.
Many of us want to cool off in a backyard pool, but we also want to make sure there are no dangerous bacteria lurking in these pools that do not have any filtration system in place. You can use Clorox® Regular Bleach2 to treat the water in a child's wading pool.
Slow sand filtration is a rentable biological water disinfection method that is capable of reducing the amount of algae, fungi, bacteria and some viruses (e.g. TMV not) in the water. When combined with aeration, the filter can also remove calcium and iron from the water.
The last thing you want to do is vacuum algae manually, which will contaminate your filter. Your pool will not clear up. In fact, the chances of your problem getting worse are very high. You'll also need to vacuum to waste when there is a large amount of debris or leaves in the pool, usually at opening.
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.
Just like you run vinegar through your coffee pot to get rid of calcium buildup, white vinegar can wipe away this eyesore in your pool. Mix a 50/50 solution of vinegar and water, dip a sponge or soft cloth into it, and scrub that residue away.
Run the filter for 24 hours and backwash the pool filter around 4 times during the same day to get faster results. DE filters will clear green pools 50% faster than a sand filter.
