The best way do eliminate scaling is to drain and acid wash the pool. Period. There are several products that claim this can be done but the expense is not worth it. $140 worth of chemicals for lousy results. A pool company will do the drain and acid wash for about $100 more and it will look brand new, PLUS, refilling the pool you'll have the opportunity to gets the chemicals balanced from day one.
The best process to try to avoid the draining and do it yourself is not easy and is very labor intensive, and often the results are not ideal.
You will need to start by dropping the overall pH in your pool to below 6.5. Adding muriatic acid about a 1/2 gallon a day will do this but it is not recommended during swimming season. (bad for the skin and eyes) There is also the expense of the acid at about $9 per gallon. It may take SEVERAL gallons across several days to acquire the 6.5 or lower pH level. Remember only a 1/2 gallon a day on most average sized pools, otherwise the acid will eat away at the metal components in your equipment.
Also if doing this in winter time, turn off any heater equipment, low pH will hurt the heating element.
Then once the pH is low enough, brushing daily with a stainless steel sweeping attachment is necessary. After about a week or so the scaling should soften.
Often times some 300 grit wet/dry sand paper is needed for the bad spots, but good luck getting to them with not wanting to get in the pool.
yes it does, but you have to wash it out with acid all over your body... STRONG ACID
hydrochloric acid
The mouth wash is frequently acidic.
Drain, pressure wash, and acid Wash the pool. If the plaster is old, it should be resurfaced. Resurfacing the pool will give you a new warranty and a longer life on your pool.
I have not personally used Zep sulfuric acid drain cleaner.
To effectively use sulfuric acid to unclog a drain, carefully pour the acid down the drain, following the instructions on the product label. Allow the acid to sit for the recommended amount of time, then flush the drain with water to clear the clog. Be sure to wear protective gear and work in a well-ventilated area when handling sulfuric acid.
Drain and acid wash
Acid wash style jeans have a designer look to them.
The sulfuric acid did not clear the drain because it may not have been strong enough to break down the clog or there could have been a blockage that the acid could not dissolve.
To effectively perform a bathtub drain repair, you can start by removing the drain cover and using a drain snake or plunger to clear any clogs. Next, inspect the drain components for damage and replace any worn parts. Finally, reassemble the drain and test it to ensure it is working properly.
Sounds as if you did not filter the pool water for at least 24 hours before adding chlorine. You also may have added too much chlorine at one time. That brown is iron and if you did not react to it immediately it will most likely be somewhat perminant. If pool is plaster a light acid wash will usually correct. The acid wash can be done in two ways; with the water in the pool, sometimes called a no drain acid wash or pump out water and acid wash in the regular manner. Must be professionally done. Sorry to hear of you rmisfortune. Ken
Drain the pool, acid wash it, refill, apply proper chemical levels, easy as that!
