What would you like to do?
Our pool guy comes in the early afternoon/late morning every Monday. I check the pool PH around 5 pm, and the readings are all right on.....so I would say five hours? That's our pool, though, I would get one of the PH testing kits you can get at pretty much any pool supply store.Hope this helps!Mrs. Gregory Our pool installer told us to wait 3 hours after adding acid to the pool. We use the liquid form, so I don't know if the wait time is different for other forms.

Initial care must always be taken when handling acid don't add concentrated acid directly to the water, it is safer to dilute it in a bucket first, and wear eye protection…. Acid can be washed of by using copious amounts of water to dilute it. This depends on the pH of the pool at the time and the size of the pool as well. In the past normal practice was to have a test kit on hand to test the pH of the water, which should fall some where between 7.2 and 7.6. And from the results calculate the amount of acid that needs to be added to the pool. These days it is easier to take a sample of water to the pool shop where it can be electronically tested, giving you exact requirements re the pool water (this is usually a free service). There is any number of ways for testing pool water just check with your pool shop or browse the web to find the method that suits you best. You can easily calculate how much muriatic acid to add using this pool wizard calculator. Always be careful with acid if you have a stained concrete deck, you will ruin the stain. Having a properly balanced pool is not difficult, but it does take work. I'm the pool operator at our local YMCA and keeping an 80,000 gallon pool balanced is pretty easy, once you all the elements in place and know what you're doing. Chlorine 3.5-4.5, alkalinity 80-100, pH 7.6-7.8, not 7.2, hardness 150-250, not up to 400. You have to stay on top of it because the chlorine can go down in a matter of hours if no one properly checks it. Amount of acid depends on you pH and/or alkalinity level. See the chart in the link below for an exact dosage.
About half hour if you are already circulating the water. k
YES. USE ABOUT TWO PARTS WATER ONE PART ACID. LET THEM SOAK FOR A FEW HOURS THEN RINSE. Muriatic acid can be used to clean filters, HOWEVER there is a proper sequence to clean…ing the filters. I am asuming you are talking about cleaning either cartridge or DE filters. If muriatic acid is used first in the cleaning process you will set the oils permanently into the filter material and ruin the filters. You MUST remove the oils from the grids (cartridge and DE) first then rinse with water. Next you can use the muriatic/water solution (1:10), then rinse again. To remove the oils from the grids or cartridges you can use a a cleanser manufactured for this purpose that you can purchase from your local pool & spa supply store or you can can use a TSP & water solution. TSP can be purchased at your local hardware store. Cartridge filters can loose approx. 20% of their capability with every filter cleaning. It is important that the filters cartridges be replaced every so often. Steve Dunn Vice President - Sales Commercial Pool Systems, Inc. Note: A 20:1 ratio (water to acid) should be sufficient for most situations. Even at this strength, it takes a lot of material (e.g. baking soda) to neutralize the acid for safe disposal.
Answer After you "shock" a pool with chlorine (a large amount to potentially kill anything that has been growing in there - bacteria from human waste, algae...),… you should at least wait 24 hours if it is a small pool. If you can still smell a very strong odor from the chlorine, stay out longer. Larger pools with large filtration systems (such as public pools) usually 2-3 hours is good.
If you use acid you run the risk of the stuff turning yellow in the fairly near future Usualy grout only goes murky on the sulfate so the best thing to do is scrub it do…wn wit some thing like a stianless steel scrubbing pad (a stinker of a job) then after that is done and only if it is dry paint it with a clear silicone waterproofing sealant designed for grout or bricks to make your cleaning job last longer.
It can be used to remove rust stains caused by swarf or some metalic object lef laying in the pool. however if the rust is a result of reinforsement having come in cotac…t with the water No.
Yes, you are supposed to add it while there is water in the pool. Add with filter running near a return line. Add it slowly and if possible, brush the pool to help… mix the acid. You can swim within 30-60 minutes.
You can use it straight away it mixes very rapidly and if you swim in it it will mix even more quickly.
You should wait at least 15 minutes before swimming after you add muriatic acid. If you can wait 30 minutes to an hour, it is even better.
If you use it full strength on a plaster pool you will actually "etch" the plaster and weaken it, so you must dilute it with water. Start out weak with one part acid to four p…arts Muratic acid. If this has no effect try a mixture with fewer parts water. You want to err on the weak side, so as to not do damage to the underlying plaster surface. If the acid turns yellow and puts off a (sulfur smelling) cloud of fumes ( keep your distance from the fumes and always wear thick rubber gloves, rubber boots and eye protection) the reaction is probably too extreme. Keep a water hose handy to rinse the area off and stay out of the way of the draining acid/ water mix. Keep your acid spraying crew to a minimum, as you might accidentally spray another worker. The best set up would be one person sprays the acid mix from plastic spray bottles (buy some new clean ones at the store, because used ones may some residue which might react unpredictably with the acid.) and the other mans the hose and spray it off, once the first person is clear. We are working on a 28 year old plaster pool in Kansas.
Muriatic Acid is used to lower the pH in swimming pools. It's also used to lower alkalinity. But, there's a way to lower pH and really not touch the alkalinity, an…d vice versa. pH and alkalinity and opposite sides of the same coin and you need to know how to add the acid with minimal effect on the other side. www.clean-pool-and-spa.com give all the information you need
It depnds on the amount, but a good rule of thumb is wait at minimum one hour before swimming. You pool water may contain "hot spots" that still have acid. If you swim… through one of those, well, you'll probably feel like replacing your eyes.
Muriatic acid is toxic. You need to wait until all the water in your pool turns over and that depends on how many gallons your pool has and how strong your pump is. You are sa…fe by waiting at least 4 to 6 hours with the pump running. And remember: Only add a quarter of a gallon at a time and put it in the deep end of pool.
not long term, I would be more inclined to go with polypropylene.
You can, but you run the risk of altering the pH of the pool water along with etching the cementuous material (other than the tile) that the acid might touch. The acid is co…rrosive, so be careful. I would suggest diluting the acid prior to using it as a cleanser. Use a product such as Scale-Be-Gone and you should get satisfactory results. Beware of glass bead blasting the tile as it damages the glaze on the tile and it will get scaled up faster than it did the first time.
Muriatic acid is most commonly used in swimming pools to lower the swimming pools PH and to lower the pools alkalinity. You should use caution when working with muriatic aci…d. Not only can it stain your clothes, pool deck, etc, but if you inhale too much it can cause tissue damage. Always consult a professional when working with chemicals that you are not completely knowledgeable about, some swimming pool chemicals when mixed wrong can have a chemical reaction and catch on fire.
At least 5 hours .If you don't think its ready,wait 2 more hours.
