To start treatment, shock your pool with hydrogen peroxide by adding 250 ml (1 cup) of hydrogen peroxide for every 1000 liters (250 gallons) of water. If you are currently treating your pool with chlorine, you don't have to wait for the levels to go down, you can start using hydrogen peroxide now.
Baking soda is safe and straightforward to use, while also providing your pool with a clean, clear, sparkling water that is pleasant to swim in. Baking soda does not sting the eyes; neither can it cause drying of the skin.
There are alternatives to chlorine including bromine, ionizers, and ozonators, though with each you'll still need to use some chlorine. A fourth alternative is PHMB, which doesn't require the use of any chlorine. All four have drawbacks, including cost.
A rule of thumb is 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool's pH tested below 7.2, add 3-4 pounds of baking soda. If you're new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.
The benefits of swimming pool salt
Using swimming pool salt instead of chlorine delivers greater swimming comfort: Swimming pool salt does not give off an unpleasant odour as chlorine does. It is much less harsh on hair and skin. It does not cause your eyes to sting.
Bleach is safe and the only chemical you should be using in your pool unless cleaning pool tile with baking soda. So yes, you can use bleach to keep your pool water chemistry balanced.
In addition to being cheap, vinegar is a non-pollutant and harmless thus considered a multipurpose cleaner you can use for your swimming pool. Vinegar contains acetic acid which makes it a great disinfectant. It is also acidic in nature hence removes dirt, grease and mineral deposits.
If you need to mildly shock a 30,000-gallon pool by raising the free chlorine concentration to 5 ppm, you need 2.5 gallons of bleach. To raise it to 10 ppm, you need 5 gallons.
Common unscented household bleach (sodium hypochlorite) works well to shock a pool.
The use of baking soda in pools can spot treat algae
It can turn any backyard pool murky green or cause unsightly black spots on the walls and floor of any swimming pool. If your algae come in the form of black spots, it can be extremely tough and frustrating to try and get off your pool's interior.
Mineral Swim is the only system of it's kind combining Australian made ozone water purification technology with 100% natural Dead Sea minerals to make it the safest, healthiest swimming pool about.
Shock-chlorination is an essential and effective method of cleaning the pool. But you need to have the pump circulating the water for this to be effective.
Superchlorinate after rainstorms or heavy pool use, but for algae, chloramines or contamination, you will need to use packaged pool shock. In summary, shocking a saltwater pool is no different than shocking any other chlorine pool.
So, not only is shocking a saltwater pool okay, but it's actually important to your pool's health. Shocking is the process in which you overload your pool with chlorine (3-5 times the normal amount) to improve your pool's cleanliness and kill off organic matter.
Natural Cleaning Agents for Pools
Baking soda: This is a great cleaning agent in general that also works well in swimming pools. The active ingredient in baking soda is sodium bicarbonate, which breaks up algae and allows you to scrub it and clean it from your pool.
Natural pools rely on filters and moving water to do all the heavy lifting. Natural pools are constructed with walls or membranes that keep out soil and silt. They can be created from scratch or converted from an existing in-ground pool system.
Short answer: yes. Longer answer: it depends on the formulation. The label on every bleach bottle should tell you the ratio of sodium hypochlorite (and available chlorine) in the bottle to everything else. A higher percentage is generally better, as you'll need to use less bleach to treat your pool.
Chlorine is a sanitizer, and (unless you use Baquacil products) is necessary for maintaining a clear and healthy pool. Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly.
Swimming pool shock contains 12.5% sodium hypochlorite (bleach) vs. 6-8.5% for Clorox (bleach). Some Clorox products go as high as 8.5%. At a 12.5% concentrate, liquid pool shock is approximately 2x's stronger than Clorox bleach.
In short, no. You should never put Epsom salts in either your spa or swim spa.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
