Having a swimming pool in your backyard can be a fun way to keep cool during the hot summer months. But maintaining a pool is also hard work, particularly if you want to keep the water crystal clear all season long.
The key is just following these 3 easy-to-follow tips
1. Maintain proper disinfectant levels.
Every pool, even the best-kept ones have germs and bacteria but keeping the chlorine above 1 ppm will eliminate them. Algae are plant forms and they require nutrients in order to survive. Once chlorine levels are low and the environment is right algae can appear almost overnight.
This is what is commonly referred to as “Algae Bloom” which can turn a pool completely green resulting in pool closure for at least several days to a week in some cases.
Maintaining proper sanitation levels, brushing the walls and floor of the pool, adding a small dosage of algaecide is the best way to prevent algae from turning your pool green. It is the most effective and inexpensive way to keep the water clear.
2. Assure proper filtration and circulation system
Pools are designed to have water flow through the entire system at a specific rate in order to assure proper filtration and circulation of chemicals and disinfectant.
One of the most common mistakes I see in the field is putting chlorine sticks or tablets in the skimmer baskets. Most chlorine sticks and tablets are very acidic and when put in the skimmers they quickly begin to erode the pump impeller which reduces the water flow and significantly contributes to a pool becoming cloudy or developing algae.
So, keep the skimmer and line basket clear of debris and don’t add harmful chemicals through the skimmers.
3. Mind the filtration system.
While there are many different types of filters, the most common filter in this industry is a sand filter. Sand doesn’t go bad by itself but it can be ruined by what has been added to the pool. For example, many pool operators add a blue clarifier or flocculant to get the water clear.
A high rate sand filter clarifier is not recommended and can cause the sand in the filter to “gum up” and become ineffective at filtering. So, while the water is passing through the filter it is not actually being filtered effectively.
This can result in a cloudy or green pool. Algae is small enough in size that much of it will flow between the grains of sand in many filters and just keep circulating.
There are a few products that one can put in a filter that will help trap the dead algae so it can be backwashed out of the filter and you can be on your way to enjoying a clearer pool.
