Seems like if you miss just one week of adding chemicals, your pool can take a dramatic turn for the worse. Especially during the summer here in Arizona. Once algae spores become full algae blooms, it can take several days or even weeks to gain control again. The key to fighting algae once it appears is to act quickly. Here a few recommended steps to take if the algae monster invades your pool.
More than likely the reason your pool developed algae was due to an imbalance of your water’s chemistry. Getting your chlorine and pH balance back in order should be the first thing you do when your pools starts to turn green. Some pool companies even recommend keeping your pH levels slightly higher around 7.8 and 8.00 when fighting algae.
Brush Brush Brush.. then Vacuum
If algae has developed, it has taken root on the walls and floor of your pool. You will want to dislodge the algae by thoroughly brushing your pool, especially in the areas where algae is visible. The type of brush you use, such as wire or nylon, will be determined by your pool finish. Consult a pool store if you are unsure which to use. After brushing, wait until any floating algae settles, then vacuum.
Adding super chlorination in the form of shock can dramatically improve your chances of destroying algae. We highly recommend checking the ingredients before purchasing shock as some contain more actual chlorine than others. Any pool store employee should be able to answer any question you may have, but be wary if that only suggest their ‘brand’. You will want to shock your pool at night at run your filter for a least 8 hours to maximize the effect.
To Algaecide or Not To Algaecide
In more extreme cases you may have to use and algaecide to kill the algae. There are different categories of algae like Green, Mustard, or Black. You will want to determine which type of algae your pool is infected with to know which algaecide to use.
Circulate and Re-Circulate
You will probably want to run your filter longer than normal, 24-hours if possible, when fighting algae. Be sure to clean or backwash your filter also to help remove contaminants.
Without a doubt, algae is the bane of existence for pool owners. Regular pool maintenance, chemicals, and circulation is the best way to avoid the dreaded algae invasion. But if it happens, act swiftly and you can have a clean, clear swimming pool once again!
