If you don’t, the chlorine levels will keep climbing and bleach your fibreglass pool. It is hard to see when the walls are wet but when the water line lowers and the walls dry, it is very obvious. For fiberglass applications that are constantly exposed to the sun, the finish will become chalky and faded due to oxidation. You must log in or register to reply here.
When this happens it often leads to calcium formation. As the pool filled, we scrubbed the sides like crazy and had white milky water. In most cases, our treatment kit completely removes the white calcium on fibreglass pools. Although some degree of chalking is normal and can be a desirable way for a paint film to wear, excessive paint film erosion may result in heavy chalking. Calcium Hardness was also very low all season and is currently at 150. I really don't think its a huge issue, so I have just been dealing with it. Forums
This is because your pool walls will need to be properly cross braced and secured to prevent buckling and cracking when your water is released.
The only thing I use is 6% bleach, muratic acid (not much) and on occasion a clarifier/coagulant called "Super Blue". and #3 - I don't need to worry about it. You must log in or register to reply here. I called the manufacturer and was told that it was caused by too low calcium, too high PH, and high chlorine levels.
1. For a better experience, please enable JavaScript in your browser before proceeding. Our ch #s are fairly low so ??? Every time I tested PH this summer, PH was between 7.6-8.0 and would creep right back up a day or two later so imagine that PH has been high or in the high end of normal all season.
Looks like chalk you see on fiberglass boats. It often occurs on This occurs because the uncured surface is very porous, which allows the water to penetrate into the surface resin and bleach the gelcoat. But I think their situation was different than calcium scale which we see as hard to remove.
use Tri-Sodium Phosphate(TSP)and a good brush to clean it. As the picture shows, this white layer becomes very noticeable when the pool … white residue or scale in fiberglass pool ... My dark colored fiberglass pool developed a scale or residue below the water line over its entire surface.
I disagree with the high chlorine comment from the manufacture though as the stabilizer in your water will adequately protect everything from the chlorine when balanced as noted on the [FC/CYA][/FC/CYA]. You can find products at your pool store to help remove this build up.
PH: 7.6, CH: 350, CYA: 70, FC: 9, TA: 100; so I personally don't think it has anything to do with the chemicals.. As the pool filled, we scrubbed the sides like crazy and had white milky water. For a better experience, please enable JavaScript in your browser before proceeding. It works by by softening and dissolving the white build-up without acid washing.Whitening or discolouration on a fibreglass pool surfaces is normally a result of one of the following.
I've fought this problem for years. That's a puzzle. Maintaining a great looking fiberglass pool requires keeping the water in balance by saturating it with minerals and keeping it clean to avoid the growth of algae and bacteria. My pool is 4 years old now but I started having this problem after about a year. The minerals deposit on the surface – and this is completely normal. If I rubbed it, it left a white residue that was exactly like what I'd get off of the sides of the pool. Q: What is the white film that we are getting on our tiles and grout in our swimming pool? Remember, this colour loss, which often starts after 15-20 years, is normal. I'll post their reply. It is hard to see when the walls are wet but when the water line lowers and the walls dry, it is very obvious. They recommend a calcium level of 350, PH of 7.4, and chlorine level of 1-3. We bought "Ultimate Scale and Stain Control" from Leslie's since the Scaletec version isn't found near me.
None are correlative to water chemistry.
Remember, check your water during winter, even if the pool is covered.Our treatments can sometimes help with surface bleaching.
I'm not so sure what you are wiping off with your hands is calcium. Q: What is the white film that we are getting on our tiles and grout in our swimming pool? However, such high maintenance is nearly impossible and white calcium deposits, also called scale, are probable. It sounds like I need to get calcium up to 300, keep PH lower and use the Scaletec product they recommended. . Do not sand your fibreglass with any type of abrasive as this will cause permanent damage and may void your pool warranty.Some pool owners believe that testing the water during winter (or when a pool cover is on) is not necessary. We will gladly look at pictures of your stain and discuss options with you before we come out or send a kit. Lots of hits on this forum. Not sure what products you are using there but that would be one of the first things to check.
my uncle had this problem when he used Calcium based shock / chlorine products--after switching to a SWG --this problem has since gone away. High pH levels in the pool water will cause any calcium in the pool water to bond to the pool surface.
The chalky substance is most likely too much shock.
Firstly, the gelcoat blue colour will slowly fade to white over time.
This year there had been a huge amount of pollen in the pool, I think we have mustard algae because when you touch or brush it the pool is cloudy.
