How to Clean Green Pool?

It has been said water is life; but frankly, water is only often useful when it’s clean. Whether for cooking, washing, drinking, a swimming pool; the water has to be clean in order for it to benefit us. Unclean water is hazardous for consumption; swimming in dirty water is a sure way of inviting skin infections and other diseases. There’s more to clean swimming pool water than just a clear appearance; usually, the water has to have a PH of 7.4, it has to have the correct alkalinity, and the right amounts of chlorine used.

When it misses out on either one of these things especially when chlorine levels are insufficient; it creates a chemical imbalance and the end result is the growth of algae in the water. Before you know it the water has turned greenish and with a cloudy color.

  • Green pool are usually cleaned by filters such as; a sand filter, cartridge filter or what’s known as a DE (diatomaceous filter). Faulty filters can contribute towards the water appearing green.
  • Insufficient levels of chlorine can also make the pool to appear greenish; it’s important you always use the right amount of chlorine, too much or too little will have effects.
  • When leaves from nearby trees fall into it or when fertilizers sprayed near the pool get in contact; these create an algae problem, which in turns the pool green.

Cleaning a green pool:

Before you begin to clean the green pool, find out exactly what could be the cause of it. Use this checklist;

  • Check the water’s PH level
  • Does the water stink, is it sticky?
  • Check and ensure all filters are functioning properly.
  • Is there any unwanted water getting into it? Maybe a broken pipe directing water into it, rainwater draining into the pool, and such.

Identifying the problem is the first step towards finding a remedy.

Steps to cleaning a green pool:

  • Cleaning a green pool must start by thoroughly cleaning the bottom, sides with an algae pool brush. Don’t add any chemicals yet, brushing the floor and walls loosen the algae and make it easier for the chemicals to be more effective later.
  • Check the pool PH and balance it; this is done by either increasing the PH with sodium carbonate or lowering it with sodium bisulfate.
  • Buy some pool shock; it’s a chemical commonly used to kill bacteria and algae, it has chlorine elements in it.
  • Go ahead and shock the pool. The green pool’s PH level should be low as shocking it automatically drives the PH levels up.
  • In order to do a perfect job, start by knowing what type of filter the pool has it has; a sand filter requires liquid chlorine so as to prevent any residues, while a DE filter does fine with granular chlorine.
  • During the shocking process, ensure that the pump is running non-stop for at least 24 hours.
  • Shocking will finish the greenish appearance on the water, but it is possible that it will still have a cloudy appearance. Brushing and filtering can remove that cloudy appearance and give way to a clearer appearance.
  • Chlorine should be poured evenly over the water and given ample time to mix.

The amount of time needed for the cloudiness to disappear depends on the type of filter used. A sand filter may take 7 days or more, cartridge filter two days, while a DE filter may clear up almost instantaneously.

A very green pool:

There are times the pool may be too green that even when you submerge your hand, you can’t see it.  In such scenarios, mere shocking won’t be enough and you may need to completely drain the pool and wash it with acid. While some may find emptying and refilling their pools as a bit pricey, it is worth it in the long term.

Prevention is better than cure:

  • Spend at least ten to twenty minutes daily to inspect your green pool for any algae, insects, foreign objects like leaves and plastic bottles, and the likes.
  • Adding chlorine at the right intervals, right amounts will go a long way in keeping your pool safe and clean. If need be, try using chlorine floaters or a salt system.
  • Too much chlorine can have effects while too little isn’t helpful either; know the right amounts to use and how frequently you need to.
  • Remember to always clean the filters as required. DE filters need to be cleaned monthly, sand filters once every two weeks, and cartridge filters after every four weeks.

It’s important that users always shower before and after using it. It shouldn’t be used when a major cleanup is undergoing, users should be patient to let the pool get restored to a perfect state.
