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!
- Ensure your pool’s pH level is between 6.8 - 7.2
- Ensure alkalinity level is between 80-120ppm
- Backwash the pool filter for 2–3 minutes.
- 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.


- Run the pump for 8–12 hours, then resume the normal pool cleaning cycles.
- Brush stubborn algae if necessary, then vacuum or allow filtration to remove dead algae.
- 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.
