Goggles and gloves also good to use. The pool is about one year old.I notice this white stuff all over the sides of the pool. Well I took some water in to a pool service to have it checked. Using huge truck mounted reverse osmosis filters and water softening agents and pH control, they can pump your entire pool through the truck a few times and return to you fresh and balanced pool water, with calcium hardness removed to an appropriate level.There are still some old pool guys that insist on this method, but it can be risky. Is this calcium? My pool service company tells me it is calcium. The pool is 18000 gallons. If the calcium buildup on your pool liner is severe, you may have to replace the liner.I have a rough raspy build up of some sort on the pool bottom and sides of the liner under the water level. Remember that 7.0 is neutral, so 6.8 is barely… acidic, and would have little effect on scale. If the test reveals that the levels are within range, you can use a stain and scale remover to remove the deposits from the water line. Scale deposits can form along the waterline of your swimming pool. Regular use of a sequestering agent can help keep calcium in solution. Another less effective way is to plug the plumbing, remove the light, and add enough acid to the pool to drop the alkalinity to near zero (about 1.25 gals), which will dissolve most or all of the scale, then use a sequestering agent (Stain Away, Scale Free), to keep the minerals in solution.
Poor communication from the owner/comany. This will stop calcium deposits and reduce calcium buildup. I would not leave the calcium deposits on too long. As soon as they are obvious, balance your pool chemicals and remove the deposits. ThanksSure Stephen, there are a number of sealers that can be applied to the tile, or painted onto the grout, grout sealers. The amount needed of either chemical will vary depending on the pool size (gallons) and the alkalinity reading. Pool was drained, and some parts can be cleaned ok with a pressure washer, but some have a hard white build-up that will not come off with pressure washing. Once the pH is balanced, we can move onto the final step. The plaster in some areas are dirty looking. You will want to re-test before doing so because the alkalinity should be lower than before. 6.8 is not very acidic, but over time, it can etch and erode pool plaster or vinyl, or chrome and rubber materials. The service never mentioned I had deposits. Will this product help me?Yes, an acid-based surface or tile cleaner will help remove the calcium build-up. Would it be harmful to just keep our ph level at 6.8, to prevent future calcium build-up?Hi Edward, yes it can harm the soft and shiny pool surfaces. Repeat if needed, but be gentle as it degrades a plaster surface as well as the scale. Now in 2020 am seeing calcium deposits over the bottom of the pool. It is also a bit uncomfortable for skin and eyes. I live in California and of course everyone knows we have been in a drought. And I hate to tell you, but can come back again if the sequestering agent level dips, or for other reasons, like hard tap water, or shocking with calcium hypo. You can then seal the tile or stone, to prevent future deposits. Soon after the filter was replaced the calcium deposits started to appear. Sealers can be used on the tile to provide an invisible barrier. Two treatments were done Supposedly. The same process that creates stalagmites.Sometimes the moisture comes from the pool as shown below. Help! The best way to remove scale, if Jacks Magic did not work would be to drain the pool and acid wash – or do a Hi, our entire vinyl liner walls feel like sandpaper….our water is crystal clear and chemical levels are almost perfect…can u break it down in laymens term on how to remove this what appears to be scale. Exactly how do u lower pH and know if its within range to start treating the scale? All chemical should be in balance but pH, Alkalinity and Hardness and critical to resolve this problem. Black or Grey plaster pools develop the same hazy calcium films but are quite noticeable. Should I use scale free vs stain away?Hi Nicole, I would first try lowering the pH to 6.8, by adding enough pH decreaser to get there. Calcium or sodium salts typically leave a white deposits. We use the outdoor water hose bib to fill the pool and the auto fill.I’ve read about dedicated water systems, RO systems etc…Money is always an object but it can’t be as much as a life time of chasing these issues.Please feel free to suggest any brand or particular systems to consider.Hi Don, many people live in hard water areas, like yourself, and they all share your problem of calcium deposits, very visible on the waterline tile, but not always so visible on white pool plaster, but it’s there… To reduce scaling, or the precipitation of calcium from the water:As for #4, not sure why you can’t use the slat treatment system, not sure what that is. If you have a company like PuriPool or Calsaway in your area, they would bring a portable system to your pool to filter it. anything below 7.0 (neutral), is in the acidic range. It will not allow a breakdown of calcium, but it does make chlorine more potent.
If the pH, alkalinity or calcium levels are too high, they will need to be lowered before using a stain and scale cleaner. Most likely your hardness and pH are too high. I put it in two days ago, with no change in appearance today. The idea is to carefully raise the pH with If you have a sand filter, you can replace regular pool filter sand with Calcium carbonate scale can form along the waterline of the pool as evaporation increases during the summer. It can be seen coming out of mortar joints between stones on a raised rock wall, or can drip down onto pool perimeter tile, flowing from the mortar bed beneath pool coping stones.Efflorescence can be slowed by using Clear Sealer on rock or brick faces, and making sure that pool caulking is maintained to keep water out of the expansion joint.
