Rinsing and cleaning perlite
How it's done
Before you put a plant into the perlite, it should first be cleaned and rinsed.
The best type of water to use is rainwater or distilled water.
Rinse perlite thoroughly two times.
Third rinse should be with already prepared water that is going to be used in the tank, with added nutrients and regulated pH between 6.2 and 6.5.
