Stains are a normal occurrence in swimming pools. No two stains are alike and what may work for one type of stain may not necessarily work for another type. One stain may appear brown in a pool and yet appear green in another. Before applying any cleaning products you need to follow some steps for pool care in Townsville
The number one rule in the removal of pool stains is to test it.
A stain can be defined as something that changes the surface of the pool’s appearance and has a detrimental effect to the pool. A scale is classified as a stain that has metal as well as dirt. A scale is actually a calcium carbonate deposit that appears on the surface of the pool.
Stains are caused by a chemical reaction of chlorine in the water with metals that are introduced into it. Some metals that are commonly introduced in pool water include: Liquid chlorine whose component is iron. Continuous use causes the iron to build up forming yellow to brown stains. Salt is another cause of green, yellow and brown stains. Another source of metal is the top up water especially if it is sourced from a bore hole. Borehole water contains quantities of copper, manganese and iron. Algaecides that contain copper, nickel or silver causes the pool surface to have black stains. Metal fixtures in outdoor pools with cheap stainless steel walls and ladder can rust and cause stains to form in the pool. Organic stains are caused by growth of algae, stains from leaves that fall into the pool or dirt that is left in the swimming pool for more than a week. The pH imbalance in water can also cause stains. When the pool water is too acidic or too alkaline then it will cause stains to form.
It is always important to first look for the cause of the stain to avoid its recurrence. Stain removers like citric acid are not a permanent solution. Chlorine is able to break down citric acid over a period of time which eventually causes the stain to reappear. Salt is the leading cause of pool stains.
Once you determine the cause of the stain, you should embark on testing the stain. This way you will be able to determine what caused it in the first place and how you can prevent it from reoccurring in the future. You will also be able to determine the stain components, the length of time it will take to remove it and the possibility of the permanent removal of the stain. The first step you will need to take is to inquire from the owner on the recent activity concerning the pool. Find out from the owner; if they have a leaf problem and if so, do they leave the leaves for long periods of time? Did the stain form after using salt? Have they used an algaecide that is copper based? If there has been a recent storm occurrence or if dirt has recently been washed into the swimming pool?
