Checks prior to using pool flocculant

Previous steps so that you know when it is really necessary to use pool flocculant

Next, we present whats previous steps so that you know when it is really necessary to use pool flocculant:

  1. Measure the pool values ​​and adjust them (the pool's pH level, alkalinity, chlorine...)
  2. Remove surface dirt.
  3. Remove dirt from the walls and bottom of the pool.
  4. Check that the skimmers are not clogged.
  5. Clean the pump filter, that is, thoroughly clean the pool filter.

Ultimately, Flocculating pool water is a necessary process when there is a lot of dirt in the pool water. and there is the presence of tiny particles that threaten its transparency.

These particles are an indication that there is a lot of organic matter in the pool, as well as dust, rain mud, the presence of calcium and magnesium salts and the oxidation of manganese and iron salts.

How pool flocculant works

In the process of action of the flocculant for swimming pools, commonly called water flocculation, we will add the chemical product in one of its different formats to the pool.

Flocculant operation for swimming pools

  • Actually, pool flocculant does not remove anything.
  • Rather, it collects and agglutinates the smallest particles in the pool, causing this fine dust or dispersed sediment to concentrate.
  • And in this way generating a collection of  locules (dirt formed by small flakes).
  • Secondly, the flocs end up weighing more than the water, which is why they end up being decanted to the base of the pool.
  • Then, as we have already said, once 24 hours have passed, the particles must be collected with a manual or automatic pool cleaner.
  • The rest of the particles not collected will be trapped in the sand of the pool filter. Consequence that even though they are smaller than the rest, they will have become sticky and will remain stuck in the sand or glass of the pool filter.

How long does it take for the flocculant to take effect?

In response to how long it takes for the flocculant to take effect: Approximately it takes between 8 and 12 hours for the flocculant pool brings the particles to the floor of the pool.

  1. The first step to start the procedure on how to flocculate a pool should always be to check and adjust the values ​​(7.2 and 7.6 (pH), and between 0.5 and 1.5 gr/l (chlorine)).
  2. Second, wash the pool filter.
  3. Then, change the multifunction valve to the off position. recirculation and pump stopped.
  4. Know the volume of water in the pool in cubic meters (m3) that has the pool.
  5. We will apply the dosage amount of the flocculant according to the cubic meters of the pool and will depend on its format (you can see the specifications below).
  6. Leave the pool purifier in operation for 24 hours so that dirt flocs can form and fall.
  7. After 24 hours, change the multifunction valve to the filtration position.
  8. Next, we connect the manual pool cleaner and vacuum while filling the pool with water with a hose.
  9. The cleaning and particle collection process is done with gentle movements so as not to stir the water.
  10. At the same time, we activate the pool purifier (the dirt will be trapped in the filter).
  11. All this, checking while we are carrying out the removal of the rubbish and every so often that the manometer of the sand filter does not rise in pressure.
  12. If we are cleaning and see that the pressure increases, we will wash the sand before continuing to vacuum (to prevent the filter from clogging).
  13. Next, we wash the sand from the pool purifier.
  14. We carry out a new 24-hour pool filtration cycle in progress to purify the water.
  15. Check the condition of the sand in the pool filter: If it can be moved and is not sticky, perfect, but if not, change the sand due to poor conditions.
  16. Finally, if the sand is in good condition, wash it last.
