With the hectic swimming pool closing season upon us in this part of the United States, it’s a great time to address POOL STAIN PROBLEMS. As you know, we recommend balancing swimming pool water, removing stains, and using Waters Choice enzymes during pool closing. It makes good sense and secures that opening your swimming pool in the Spring will be much simpler.
Pool Staining Problems
Pool staining problems are easy to ignore during the swimming season but in our opinion, they really should be addressed before closing your pool for the winter.
Identify and Diagnose
Identifying the stain problem BEFORE you treat it is a MUST. Not all stains are the same so it’s important to figure out what is causing the it before you begin broad-spectrum treatment.
In fact, according to an article in aquamagazine.com, swimming pool owners will often enter a pool store and say their water is green. Pool staff will often respond by selling a copper algaecide to remove “algae” which actually can make the problem of green water WORSE.
In the event that happens, make sure to let them know whether your pool water is CLOUDY and GREEN or CLEAR and GREEN. If water is clear with a greenish cast, the likelihood is high of copper being in the water. Likewise, if the pool water is taking its green color from algae, it will also appear cloudy BUT the walls and floor of the pool will be slimy to the touch.
Copper Stains (Blue Green)
Another key point in the aquamagazine.com article is that copper stains are probably some of the most common stains found in swimming pools. Notably algaecides, heat exchangers, and older copper plumbing can introduce copper to your water as well. Most copper stains can be prevented simply by following dosing charts and maintaining proper pH levels in pools.
We love the color purple but not in our swimming pool water! Copper cyanurate staining is caused by having a cyanuric acid (CYA) level over 100 ppm that combines with copper in the pool water to form a purple precipitant on the surface of the pool, tile line, skimmers and pool cleaner. The problem will persist until the CYA is lowered to about 50 ppm. Draining pool water to lower the CYA addresses the issue as well. Perfect for swimming pool closing.
Iron stains are brownish in color along with a possible brownish tint to the water. Pool heaters are made of iron and over time the protective coating wears down inside, exposing the iron base metal to your pool’s water chemistry. Moreover, an erosion tablet feeder plumbed in without the proper check valve in place, lawn care professionals using fertilizers and well water can add iron to your pool’s water chemistry
Of course, leaves and other organic materials make their way into pools. This organic material finding a home at the bottom of your pool can be another source of staining. In fact, it’s more common than you may think. The tannins in the leaves can leach out into the pool water and leave stains where the leaves rested. The good news is that these stains generally go away as the water is balanced and sanitized. We advocate using Waters Choice enzymes to help here as well ….
