first you find out how much is required. there is a floating device that will tell you how strong the concentration of salt is. then you simply toss the required salt into the water, it will lay there for a while and slowly dissolve.
Dilution is the only way to reduce the salt level in your pool. The pool should be tested to determine the current level of salt. The amount of gallons the pool holds and the desired salt level will help you determine how much water needs to be drained out of the pool to allow the addition of fresh water to complete the dilution process.
you just need to add more salt so it smells like the ocean and if you get a taste of it it tastes like the ocean
You run the pool for longer if your chlorinator is turned right up, otherwise you can just ad some liquid chlorine. perhaps the cell is getting a bit old and needs replacing.
Backwash your filter and add unsalted water.
Work out how much salt you require. go to a pool shop, enough salt to reach the required concentration and throw it in the pool.
Is adding water a possibility?
Drain partially and refill.
How to maintain your swimming pool in winter Clean the pool. ... Balance pool water. ... Clean the filter. ... Check chlorine levels. ... Use a shock treatment. ... Remove algae as soon as you see it. ... Reduce filter-running times. ... Set your solar heater to winter mode.
Free chlorine is the sanitizing portion of chlorine. You may not want to reduce that. Are the levels excessive? There is a product which reduces or eliminates chlorine but beware. Not a good product if you use too much. What are your readings?
the same salt water system used in a pool is also fine for a spa. the amount of chlorine generated is determined by the input current to the salt cell and the amount of time in operation.
Thiosulfate will neutralize chlorine. Buy it at a pool store.
There is no way to reduce the calcium level except by draining some or all of the water. High calcium levels are a problem mostly in the southwest part of the US. Draining a pool can be dangerous if the water table is high; the pool can actually pop out of the ground.
The pool or system was not started up properly. Those white deposits are most likely calcium carbonate. How long ago did this happen? What type of finish ~ plaster, vinyl, fiberglass? Ken
Add potash or a similar product available from pool shops.
You need to dilute or change the water only when one or both of those levels exceed desired levels. There is no regular schedule for this, as the levels and their increase rate will vary from pool to pool. Get reliable test equipment and test the water yourself periodically, or take a fresh sample of water in to your local pool store to have the levels checked.
i believe it raises your PH levels
Since your CYA levels are 250, you're going to have to drain the pool and start over. There is no chemical made to reduce CYA levels. When you refill the pool, maintain a CYA level from 40-60ppm.
Dilute it... No other way
Put a cover on the pool to minimise sunlight on the water
