Place capsule directly under the root zone of the plant you want to fertilize. Place at least 3cm /1.2" deep.
Add 1 capsule per 2.5 inch2 / 16 cm2 bush of plant. Always Change Water the 2Hr Way after replanting / adding APT Jazz. This removes surface detritus, which is the #1 algae trigger.
Observe the impact in new leaves after 7 days. Root absorption takes longer than uptake through leaves. Old leaves do not rejuvenate.
