What is algae?
Algae is the general name given to a large number of aquatic microorganisms that can conduct photosynthesis. You may be familiar with some types of algae such as seaweed or pond scum. The vast majority of algae live in aquatic habitats, and they are essential for the wellbeing of all forms of life that live in the water.
When it comes to pools, however, algae are more of a nuisance, and definitely not something you want to see near you when you’re enjoying a swim. As such, getting rid of algae is on the top of the list of every pool owner, so it’s important to identify what types of algae have found their way into your pool and purchase the correct type of algaecide to eliminate them.
Features to consider while buying the best pool algaecide
Besides the type of algae that you want to exterminate from your pool, there are other essential factors to take into account when browsing through the multiple types of algaecide available on the market. These include the lasting period, foaming, clarifying, stain removing, and price.
Type of algae
Multiple types of algae can find refuge in pools, and while there are algaecide available on the market that are efficient against them all, some products only work on particular types of algae, so it’s important to identify them before purchasing a product.
- Green algae — this is the most common type of algae that is to be found in pools across the country. You can often observe them floating in the water, but sometimes they may appear on the walls of the pool as well. When you have green algae in the pool, the water becomes less clear and you are likely to observe it also has a greenish tint.
- Yellow/mustard algae — this type of algae is much more difficult to fight because it has a tendency of coming back even after you use products that make it disappear initially. If you have yellow algae in the pool, you need to take immediate action.
- Black algae — this is by far the most difficult kind of algae to tackle because its roots can extend into grout or plaster. You can easily spot this type of algae because it looks similar to tar.
- Pink algae — appearing in small spot, pink algae is similar to fungus and can generally be found in the corners, cracks, and crevices of the pool.
Each of these kinds of algae can be eliminated and their reoccurrence prevented with the help of algaecide. Some of the products we reviewed, such as the PoolRx Pool Unit #101066
, our editor’s choice, are suitable for all types of algae, so they should be the first port of call especially if you’re not sure what kind of algae you’re dealing with or if you have more than one type in your pool or spa.
The lasting period refers to the amount of time the product is effective after you apply it to the water in the pool. There’s nothing more frustrating than using a pool algaecide only to find regrowth the next week. Most of the products we reviewed and included in our top guarantee 90-day protection, but some of them are more efficient than others. The PoolRx Pool Unit #101066, our editor’s choice, for example, has an extended six-month lasting period.
As you want to protect your pool from algae throughout the season, look for products whose effects last for at least three months. The same rule works for water tanks in water rowing machines, because normally users don’t like to change water in them too often.
If you are looking for a product that you can apply before closing the pool for winter, a 6-month lasting one would be a good choice, such as the PoolRx Pool Unit #101066
Some algae can stain the pool, but you can easily solve that problem with the help of an algaecide that eliminates stains. Keep in mind that copper-based algaecides can stain the pools themselves, so use them carefully.
Low-quality algaecides tend to add foam on the surface of the pool after you use it, and this can be rather annoying, as you don’t want to do the extra work of removing the foam together with the dead algae. You can avoid the extra hassle by choosing a product with a non-foaming formula, which allows the water to clear quickly, which means that you don’t have to wait for a long time before being able to take a dip in the pool. In order to be able to prevent foaming altogether, it’s essential to apply the product according to the instructions provided by the producer.
Most users want their water to be crystal-clear after they use an algaecide, so if you’re one of them, look for a product that clarifies the water as it eliminates the algae.
The price of pool algaecide depends on the quality of the product and the quantity you receive. Some products such as the Pool Mate 1-2150-02 only come in two 1-quart bottles, for example, so the total price you pay may be higher than in the case of other products.
You may want to look at extra features when shopping for pool algaecide, with Pool Mate 1-2150-02. For example, featuring a non-metallic formula. If you want to use the algaecide in a saltwater pool, look for a product that is particularly designed for that purpose, such as the Kem-Tek KTK-50-0006, for example.
Pool algaecide usage tips
When using pool algaecides, it’s always a good idea to go through the instructions provided by the manufacturer carefully. You should also make sure that the circulation system of your pool is in good working order and be careful to keep the sanitizer within the recommended range.
To keep the pool in tip-top condition, you should also shock
the pool weekly, as this can eliminate the algae the algaecide products might have missed.
Using a good brush to scrub the walls of the pool is a good idea if you want to keep the algae at bay, but you should also use a vacuum to help dislodge the algae spores that may settle on the wall and the bottom of the pool.
