Alpha is part of the Non Chlorine chemical system. Used with Omega, a shock treatment PH+ and PH- it is a very easy system to use. Blue Crystal provides an excellent alternative to chlorine.
Blue Crystal Alpha is used for commissioning and over-wintering swimming pools. It will effectively kill all algae and keep a pool algae-free all year round if used as instructed. It also contains and initial dose of Blue Crystal Omega which is used for long term bacterial control.
See the difference, feel the difference with chlorine free Blue Crystal.
Used with a 'shock dose' treatment of your Blue Crystal provides an excellent alternative to chlorine.
Chlorine has a different role in this situation - compared to a pool only with chlorine, in such pools the chlorine must be present and active at all times, where as Blue Crystal pools the two treatments work together so that the chlorine is completely spent and no longer present or active allowing you to swim chlorine free, while still being protected by Blue Crystal.
