Tips and Tricks for Choosing the Most Suitable Floc Pool

Suitable Floc Pool

Going to different online marketplaces or regular store products for swimming pools near the house, you can be confused by the variety of products presented there. And immediately the question “What do I need to buy?” arises in your mind without an answer. We are ready to help you answer it.

When choosing the best suitable flocculant for you, pay attention to the 5 most important criteria described below.

  • Efficiency in the pool cleaning up.

You should discover how each product is good in getting results after the cleaning process. Before purchasing you can examine some reviews of the real users where people write their experience: is the floc was effective or not. 

The main ingredient of most flocculants’ chemical composition is aluminum sulfate. For you to use this chemical effectively, make sure you follow the instructions correctly. You should also check the condition of the pool water before using the flocculant: make sure that the pH and alkalinity of the water are correct according to the instructions, etc.

Aluminum Sulfate can lower the pH level of the pool water, so with some flocculants based on this component, users are advised to raise the pH to 7.5 or higher before cleaning. We do not recommend you mix several chemicals at the same time, as this can significantly damage the condition of the water, the pool’s surface, and its filters.

For your convenience, we gathered some more information on the best products in this category below in our article. Spoiler: the most effective in pool cleaning is the Pool Basics Drop Down Liquid Flocculant.

  • Cleaning speed.

It is not a secret that a particular floc for pools is able to free of dirt up to 12 hours, another one can bring you a result after 24 hours of working or even longer. You should take this criterion into account when choosing the pool flox for yourself. If you’re looking for the fastest cleaning flocculant, we recommend you opt for Pool Mate Liquid Drop Down Swimming Pool Flocculant.

  • Contributes well to the complete adhesion of debris at the bottom of the pool.

The main difference between a pool clarifier and a flocculant is that the second chemical contributes to the small dirty particles’ adhesion and then moves it down to the bottom. This well-done function will help you to easily vacuum the pool and get rid of debris. Also, if all the debris will be debrided on the bottom there will be no necessity to clear the water 2 or more times to have a completely clear pool.

  • Easy to use.

Sometimes the process of cleaning the pool raises a lot of questions because it seems very complicated and time-consuming. Using some pool cleaners does require a lot of extra money and effort. But this is not the case with pool flocculants.

More often than not, the process of cleaning is simplified thanks to clear and easy-to-follow instructions for the product. Later in this article, we take an in-depth look at the winning product in this category. We also strongly recommend you make sure that the product comes with the proper instructions before you buy it.

  • Low consumption.

It is very important for pool flocculant users that the product is not too consumable. This directly affects how often and in what quantity it should be purchased. The most influential factor in this is the volume of your pool. This is also influenced by the purpose for which you are using the chemical: to remove a lot of dirt or to do routine cleaning. The best amount of flocculant consumption is 1 bottle (4 oz) per 5,000-gallon pool. Based on our research, we advise you of the 2 best products suitable for this characteristic: Pool Mate Liquid Drop Down Swimming Pool Flocculant and In The Swim Super Floc Out.

Why Should You Trust Our Research?

  • The most effective for removing small dirt particles;
  • The safest due to not containing chlorine that will not cause eye irritation and redness;

The Pool Basics Drop Down Liquid Flocculant is unique because it is the only tool that can remove algae.

Its chemical composition is balanced and this floc does not harm your pool’s pH or alkaline balance. If the water is too alkaline (when the pH of the water is above 7.8): this can lead to turbidity in the pool water, as well as the formation of scale on the surface of the pool and its plumbing equipment. In addition, high levels of alkalinity reduce the effectiveness of chlorine and therefore its disinfection characteristics.

This floculant for pools is also excellent for different finishes, including vinyl-lined. That way, it won’t harm your pool’s finish, whatever it may be. If you’re a fan of unique and custom pool finishes, you don’t have to worry about their integrity when using this flocculant.

This chemical has a 24 – 48 hours turnaround time, which is faster or equal to the average 48-hour work of other flocculants. It is also worth noting that it can be used even at a low pH of 7.2 in your pool. So you don’t have to raise the pH of your pool water to 7.5 – 8.0 to make it work effectively.

Pros and Cons

The Pool Basics Drop Down Liquid Flocculant has several advantages:

  • The highest cleaning up efficiency (100% of users managed to clean the pool completely with this flocculant);
  • The cheapest liquid flocculant for pools;
  • The best in removing algae;
  • The most harmless for pools’ different finishes (even with vinyl-lined);
  • Can be used with 7.2 pH water (there is no necessity to high the pH level to 7.5 – 8.0).

The Pool Basics Drop Down Liquid Flocculant also has some disadvantages:

Pool Flocculant VS Pool Clarifier: What is the Difference?

Pool

We would like to point out right away that the flocculant is not a pool water clarifier. The main difference between these means is in their method and speed of work. A clarifier for pool lifts the dirt to its top, while the flocculant lowers it to the bottom. This makes pool cleaning an easy task, as all you have to do is vacuum the bottom of the pool of clumped mud.

The main differences between these two types of pool cleaners are listed in the table below.
