The use of baking soda in pools can spot treat algae
No one ever wants to see algae build up in their swimming pool. It can turn any backyard pool murky green or cause unsightly black spots on the walls and floor of any swimming pool.
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there's not enough. But be careful—adding too much chlorine in pool water can cause those metals to oxidize and turn the pool a different shade of green.
Best swimming pool algaecide for all pools
For an all-purpose swimming pool algaecide, we recommend Kem-Tek 60% Algaecide Concentrate. This pool and spa algaecide contains 60% of its active ingredient, polyquaternium WSCP. It's effective at removing most types of algae and preventing them from returning.
The only thing that kills algae is CHLORINE (or your sanitizing product, or one of the copper-based algaecides on the market). You need to raise the level of your chlorine – shock the pool – and maintain that high level until all the algae is dead. This may take 3 to 4 days. RUN THE FILTER 24 HOURS A DAY.
Is it Safe to Swim in a Green Water Pool? Short answer – it depends. Lakes contain a full ecosystem, complete with aquatic life that feeds on bacteria and toxins. This makes swimming in green water in nature safe.
Green algae, unlike its black counterpart, is a true algae; it isn't resistant to chlorine, so you can control it by shocking the pool. If you don't want to spend a lot of money on expensive pool chemicals, you can shock with household bleach.
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.
After five to seven days, you can add algaecide to complete the cleaning process. Algaecide will work with the chlorine or oxidizer to kill and prevent white water mold from returning.
Different algaecides are used for different types of algae. For example, HTH Algae Guard10 is more effective against green algae. HTH Super Algae Guard can be used for green, black or yellow algae.
Fill the pantyhose or sock with 1 cup of finely ground cornmeal. Use 1 cup of cornmeal for every 100 square feet of pond. Use more than one stocking if your pond is large. Tie-off the top of the pantyhose.
Clarifier does take some time to work, unlike flocculent. It usually takes 3-5 days. From the time you put the clarifier in the water, you'll need to filter your water for at least the first 24-48 hours, then as much as possible. Note that if you have algae, you should take care of that before using clarifier.
If the pool is still very cloudy or green, you may need to shock it to make it safe to swim in again. First, make sure that the filter system is working properly and the chemicals are still at the proper levels. Next, mix up your chlorine shock (hyperchlorinate) treatment.
Bleach, like any other kind of pool treatment, is best used in specific concentrations -- that is, you'll want to be able to detect a certain amount of chlorine in your pool water. Too little, and you won't effectively sanitize your pool water and surfaces. Too much, and your pool water might become too harsh to use.
Household bleach, Clorox and liquid chlorine can all be used to sanitize a pool. They are all types of chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine. Household bleaches often have unwanted fragrances and colors.
Baking Soda to Raise pH and Alkalinity in Pools
But adding too much chlorine can lower your pool's pH as well as its total alkalinity.
Rainwater itself does not cause algae, but it can provide the right environment for algae. Rain will bring phosphates, nitrates and other organic contaminants into the pool. As we discussed earlier, rain also reduces chlorine levels.
Use a pool brush to vigorously scrub any pool surfaces covered in algae, including the walls, floors, and steps. Apply a green algaecide according to the directions on the label. Let the water circulate for 24 hours, then brush the pool surfaces again. Vacuum or backwash to remove any remaining dead algae.
