Activator D Instructions

Using Activator-D is simple, just follow these steps

For best results your water pH should be between 6.8 and 7.2.

Ready? Let's start!

  1. Ensure your pool’s pH level is between 6.8 - 7.2
  2. Ensure alkalinity level is between 80-120ppm
  3. Backwash the pool filter for 2–3 minutes.
  4. With the motor running and the valve set in filter position, add the Activator-D powder to the weir, then add the liquid immediately afterwards. Do not pour directly into the pool.


  5. Run the pump for 8–12 hours, then resume the normal pool cleaning cycles.
  6. Brush stubborn algae if necessary, then vacuum or allow filtration to remove dead algae.
  7. Repeat the treatment monthly and enjoy your clearer pool.

If you have a pool that is used regularly by a lot of people like a hotel or public pool, consider adding a little bit of chlorine to the weir.

For the best results we recommend adding one cup of chlorine to the filter per 3-sand-bag-filter every week. It is important to add the chlorine directly to the weir, to ensure it is properly absorbed in the system.
