Algae growth can be a real problem, especialy in pools! There's nothing worse than having to clean out your pool (and its filter) constantly due to an algea infestation. But there are ways to reduce it without using chemicals. Investing in a good quality cover is one of them. It will protect the water from dirt and debris, which helps stop algae growing in the first place!
The cover also keeps sunrays out, as these can cause algae bloom. Keeping the water at a constant temperature is essential too, as fluctuating temperatures are another common trigger for algae growth. If you have a pump or filtration system installed, make sure you regularly maintain it so that it runs efficiently and works optimally to keep your pool clean and clear of any unwanted organisms.
Finally, stocking your pool with fish can help to control algae levels as well; some varieties of fish feed on it directly! However, this isn't always feasible for everyone and may require more effort than simply purchasing a cover. (But either way, it's worth considering if you want to keep your pool free of algae!). So when it comes to reducing alage growth without chemicals, investing in a high-quality cover is the best bet! Transitions words such as 'therefore' or 'all things considered' would work great here.
