Keeping Leucillin happy!
The purple bottle is not just an awesome colour, it is there to offer UV protection for the solution. Always keep your Leucillin in its original packaging and out of direct sunlight. As long as the solution is clear and it smells of swimming pool then it is active.
Excessive heat will denature the active ingredient so watch out for leaving a bottle in a car on a hot summers day or next to a heat lamp. Cool and dark is ideal but remember to smell the solution if you are not sure. Swimming pool = still active.
