MICROBE-LIFT Aqua XTreme is a convenient liquid, single-phase, full-function water conditioner that has been scientifically formulated for use in koi and goldfish ponds. Aqua XTreme should be used when: conditioning new water for ponds; adding (or prior to adding) water, new fish or plants to ponds; and transporting koi and goldfish. It is very important to use Aqua XTreme when adding water to a pond that contains chloramines. Conventional dechlorinators will detoxify the chlorine in the chloramines but do nothing to the ammonia released from the chloramines. Aqua XTreme will detoxify both the chlorine and the ammonia in chloramines.
