“What are those white marks on my pool?” It’s a question we hear around here a lot, and truth be told, it’s not one that can be answered in a few words. This is why we took the time to make this quick post to go over some simple facts about the issue so that you have the information you need to know what’s going on with your pool and what to do about it if it’s something that needs to be addressed.
In the last few months, you may have noticed white patches or white circles in your swimming pool. Sometimes they are hard to spot, but they are there. These spots are a problem that can turn your popular swimming pool into a neglected one. It is probably because the water quality in your pool has deteriorated and the chlorine levels are so low that algae have started growing on the inside walls of your pool.
White marks in your pool are a sign that you need to call a professional to take care of it.
White marks on the bottom of your pool are often caused by calcium. Calcium is a mineral that is found in many pool water treatments and can build up on the bottom of your pool. They look like dirt, but they’re not. They’re mineral deposits that form naturally when chlorine reacts with dust and dirt on the bottom of your pool. These white stains are usually not harmful, but they can cause irritation if they get on your skin or in your eyes. Calcium can also interfere with the efficiency of chemical cleaners in your pool, which means you may need to use more chemicals than usual to keep the water crystal clear.
White streaks are also caused by algae in pools—they grow quickly and produce an algae bloom (which makes more algae!). Algae blooms are usually caused by high levels of nitrogen and phosphorous in water, which can come from many things including urine from pets or humans; fertilizers used around houses; cleaning products used around the house or poolside; even lawn chemicals like weed killers or pesticides!
If you have white stains in your pool, it’s important to get them removed as soon as possible. Here’s why:
1) The stains are unsightly and can ruin the look of your beautiful backyard oasis
2) Calcium deposits can scratch tile finishes, which will require expensive repairs down the line
3) If left untreated, calcium deposits can cause permanent damage to your pool’s finish
4) Once you start having problems with white marks in your pool, it isn’t long before other issues start popping up as well: cloudy water and algae growth are two common results of having too much calcium in your water.
White marks on the bottom of your pool mean there’s something wrong with the water chemistry. That’s bad news for your pool—and for anyone who uses it to have fun or relax.
