If Premium 5 Granules and Tablets have ingredients to combat algae, why do I need to use a long life algicide (or vice-versa)?
The idea is to use the Premium 5 Long Life Algicide to achieve an effective concentration on opening the pool up at the beginning of the season. Thereafter, regular additions of the Premium 5 chlorines, either in granular or tablet form, will simultaneously add a little bit more algicide and water clarifier to replenish what has been lost in combatting algae, backwashing etc.
