Cloudy water – it is as a result of inadequate filtration, which signifies either the daily filtration is not enough or the filter is dirty. The solution to this problem is pretty simple; always inspect the filter grids for separating seams or holes, especially given the fact that a DE leak through the filter can also result in cloudy water.
Also, always check the PH and alkalinity level in the pool water, as high readings could lead to cloudy water. In the case of spas, this indicates a high level of TDS in a relatively small and confined water body.
Colored water Colored water in a pool indicates the presence of metal in the water – that is, if it’s not algae. It may also signify plaster staining problems, which is why corrections should be prompt.
Green – a greenish color in the pool water means copper. It means that the water is very acidic, which is why you should always inspect the PH.
In most cases, the copper comes from heater components or plumbing, being carried by the acidic water and being deposited on the plastered walls. When left for too long, it turns black – sooty-looking materials.
When you notice the color change in your pool, turn off the circulation equipment immediately, until you figure out the real problems and their possible solutions. Then, following the appropriate measures, distribute the proper chemicals into the water. Leave it for a few hours and then take a PH reading.
If you find the PH level is back to normal, then you can turn on the equipment, if not, then keep balancing.
Also, applying copper-based algaecide might also introduce copper into the pool. So, it’s advisable to examine the chemicals you are about to apply on your pool before applying.
To remove the metal from the water, you can apply a chelating agent, which will attract the metals together for them to be filtered.
These products are available in several brands names, so choose wisely. Follow the instructions labeled on the product of your choice. Always ensure that the filter is running for 72 hours once the chemistry is balanced.
Brown towards red – this color indicates the presence of iron in the water. To solve the problem, first inspect and adjust the alkalinity level, the hardness of the water, and lastly the PH. In this process, you might need to drain the entire, for you to add fresh water.
Iron also precipitates from corroding ladders, light fixes, rails or the plumbing in the pool. You can apply a chelating agent into the pool.
Brown towards black – this color is as a result of the presence of metals like silver, manganese and other heavy metals in the water. The precipitated metal can also come from the algaecide you’ve already applied in your pool, so you should examine what you have used, and also what you use, on your pool carefully.
