Your once crystal-clear blue swimming pool is now a mucky, green mess. Even though the rest of your yard is perfectly landscaped and your deck or patio is debris-free, the pool's hue is throwing off your entire outdoor design scheme. Beyond that, the green color makes you wonder if your pool is unhealthy for swimmers to enter.
To start with, you can solve this problem. A green-colored pool is a common issue for many pool owners. Even though it's far from desirable, it is possible to fix the issue and return your backyard oasis to its pristine state. Before you start to stress over your pool's suddenly slimy appearance, take a look at what causes a green pool and what you can do about it.
The Enemy, Algae
What turns a pool green? In most cases the answer to this question is algae. Algae is present in nature. The wind and rain carry its spores, putting them down everywhere from your home's roof to the pool. Along with transmission modes that are out of your control (such as the wind), you or your family members can cause an algae infestation by using contaminated pool tools or toys.
With at least a little bit of light, warm water, and a constant food source, algae can flourish. A bloom (or group of algae) can grow rapidly, taking over your pool in hours.
The Antidote, Maintenance
In most cases a backyard pool can handle algae spores without incident. As long as the chemicals are in correct balance and you regularly clean/maintain your pool, algae spores that drift into the water won't live long enough to grow into a full-blown infestation.
But neglecting proper pool maintenance can result in a chemical imbalance. This can make your pool susceptible to algae growth and over-growth. If your pool's chemical balance is low on chlorine (due to improper care or not knowing how much to add), algae can take hold. Regular maintenance and routinely checking your pool's pH can help to identify chemical issues that may lead to green water.
Even though a proper chemical balance is absolutely essential, it isn't the only part of maintenance that impacts your pool's water. Along with lack of chlorine, a poorly running pump and circulation system can lead to algae growth.
A pump that's too small or a filter that's clogged can't keep your pool clean or algae-free. If you're not entirely sure what the proper run time for your pool's type of pump and size are, consult with a professional pool contractor for advice on your pool's specific needs.
The Hard Work, Cleaning
Maintaining your pool through monitoring chemical balance and keeping the filtration system in check is just the beginning of keeping algae at bay. Even though pool chemicals are absolutely important when it comes to preventing algae growth, you also need to regularly clean your pool by skimming and brushing. Algae feed on the decaying debris that falls into the pool's water (or that people bring into it). Without an abundant food source, algae will struggle to take hold and grow.
You'll also need to clean the filter and the interior of the pool. If you leave behind spores, you run the risk of starting a new infestation later on.
The Next Step, Algaecides
There are specialty chemicals that act as algaecides. These can remove algae and prevent it from growing. Many pool owners need to give the water a weekly or twice-weekly chemical algaecide treatment to effectively keep the problem from reoccurring. There are a variety of commercially available pool algaecide chemicals.
Always ask an expert before adding any chemical to your pool. A professional contractor can provide you with the knowledge you need to balance the chemicals and kill the algae.
