Get your pool from Green to Clean

Posted by Muller Lukacs on March 22nd, 2021

You've crystal clear pool water, and suddenly one day, you are surprised to see your pool water turning green. Well, it's not rare when you have all the pool maintenance checks set up, but it's not unusual. So how to clean a green swimming pool? It is not fit for swimming as well as not pleasing to the eye. But to not worry, there's a remedy, and all is not lost yet.

Why pool water turns green?

The solution to the question may be summarized in one single world and, i.e., ALGAE. When you also observe a little greenish shade instead of the bloomy shade of blue, it will immediately set off the alarm.

The most common reason for Algae growth is that sanitizer levels in pool water are below the optimal range. This might be as you haven't been properly testing pool water or maintaining water chemistry balance. Yet another factor to notice is when enough chlorine is not being added, this means you are preparing a property for algae to develop and take over your pool.

How to turn Pool from Green to Clean?

Vacuum to Waste

As elaborated above, the very first step in countering algae-infected pools is to vacuum the pool to waste. You could be thinking, why waste? Remember, as you start to vacuum algae and other particles from the bottom of your pool, it will be unwise allowing them back into the pool. Just move the multiport valve in your filter to Waste and keep on vacuuming. This will reduce significant algae and residue from the pool for some time being.

Proper Brushing

There is brushing, and then there's proper brushing. At crystal, we have purpose-built algae brushes that are best for this task. These algae brushes are not regular pool brushes since Algae is stubborn and would always find approaches to hold on to the pool areas. Therefore, in cases like this utilizing a heavy-duty brush instead of soft nylon bristles is a better option. Thoroughly use algae brush to cleanse the pool surfaces throughout, including the walls, steps, bottom floor, etc.

Test Water

After those two steps:

  1. Use your test kit to test the pH and chlorine levels.
  2. Use test strips to test the alkalinity levels of your pool water.
  3. Keep a record of these levels somewhere, as you will need these readings to refer to later on.

Most likely, you will observe that chlorine level is either too low or absent. Since chlorine is a sanitizing agent, and if the sanitizer level was optimal, then there could have been no algae at all.

Shock Treatment

Giving shock to the pool with Chlorine is the key step in cleaning a natural pool. Shock treatment means a high dosage of chlorine that'll sanitize the pool kill algae altogether. It is recommended to use our 90% chlorine and repeat the shock process in the pool twice within 24 hours. If the situation persists, then consider repeating the whole process.

Non-Stop Filtration

When the shock treatment has ended, be patient and turn the filter ON. Before pool water is clear, don't turn the filter. It might take few days until you notice the change.

Repeat Test and Balance

When the pool water gets cleared and not green anymore, perform water testing again for sanitizer, i.e., chlorine and pH & alkalinity. When there is a need to add any more chemicals to balance the chemistry, please add accordingly. Once all indicators are n optimal standard levels, dive in and enjoy your pool.
