No, a Magic Eraser will not clean a green pool. While an eraser placed in your skimmer might help absorb some fine floating debris or oils, it cannot kill algae, balance your water chemistry, or clear a full-blown green pool.
Magic Erasers are made of melamine foam, which can break down in water and clog the filter or potentially react with pool chemicals.
Alternatives to Chlorine In Pools You Could Consider
The fastest way to fix it is to test your water, balance pH and chlorine levels, remove debris, and run your filtration system continuously for 24 to 48 hours. If your pool still looks cloudy after that, the problem is often deeper, such as hidden chemical imbalance or algae beginning to spread.
No. Baking soda raises total alkalinity but won't clear cloudiness. In fact, overusing it can increase pH or calcium hardness, potentially making the problem worse. Use it only when total alkalinity is low, and always test before adjusting.
Ozone: preferred by many public pools
It is twice as effective as chlorine. Ozone makes water pleasant, odorless and good-tasting (it is also used to disinfect drinking water). This is why it is very popular with public pools which can amortize its high cost of acquisition more easily.
Problem: Bushes, weeds and overhanging trees trap moisture and restrict air flow around pool pumps. Soil and mulch around pumps and low areas trap water and moisture. Pump motors will last longer in dry conditions.
Surfaces to Avoid Cleaning with Magic Erasers
Clear pool water with a green tint may be from pollen, chlorine-resistant algae, or most often from a too-high pH level. When a pool's pH is over 7.8, even high levels of chlorine destabilize and cannot sanitize, and metal in your water and pool components can oxidize, giving off a greenish hue.
Once the algae is killed, some of it will be captured in the filter, but because the dead algae particles are so fine, they will settle to the bottom of the pool, usually appearing as a gray or brown dust.
Shock & Floc
Depending on the amount of algae in the pool, and other organic debris, you may need 2 to 4 lbs of granular shock or 2-4 gallons of bleach - per 10,000 gallons of pool water. Test your chlorine level the following day, and if it's low, or if the pool has returned to a greenish color, shock the pool again.
Stabilizing Pool Chemistry
Sometimes the pool's alkalinity fluctuates because of heavy rainfall, frequent swimmers, or too much chlorine being added during shock treatments. In these situations, adding a calculated amount of baking soda for pools helps restore pH and alkalinity balance.
With time the sand in your filtration system will break down into smaller particles and get out into the pool. These small particles will have no problem going through the filtration system and in the end, get mixed with dirt. This could be a reason your pool gets dirty even after you have vacuumed it.
Mineral pools are infused with minerals like magnesium and potassium, which are believed to offer health benefits. The mineral blend can leave our skin feeling smooth and may offer added relaxation. These pools still use a sanitization element, typically in lesser amounts than traditional chlorine or saltwater pools.
For most surfaces, you can use a mix of warm water and mild dish soap like Dawn to clean your patio. For concrete, stone, or brick, you may need a stronger solution, such as a specialized patio cleaner, or a vinegar-water mixture to tackle stubborn stains and algae.
Thankfully, algae has enemies — algaecide and cal-hypo (calcium hypochlorite) shock! These two chemicals are excellent at removing and preventing the growth and spread of algae.
Get a stiff bristled brush and scrub at your pool's walls and floors every day, and vacuum your pool. For green water, apply a flocculent and shock it. Shock the pool vigorously to get rid of suspended algae. You should add enough shock that it turns your pool water a blue/grey colour.
Clean and check filters
To prevent cloudy pool water from becoming a problem again, you need to make sure you're on top of your pool maintenance schedule. This includes regular cleaning and checking your pool filters and skimmer baskets to ensure they are doing an efficient and thorough job, ideally on a weekly basis.
Let the baking soda dissolve into the water. Turn on your pool's circulation system to help it disperse. Retest and repeat if needed. Between 6 and 24 hours after you added the baking soda, retest your pool's pH and total alkalinity.
In terms of accuracy, the liquid drop-style pool test kits will always give more accurate results than test strips. But for quick and easy results on a daily or weekly basis, test strips are great for a general analysis.
