Field guide
Spray, scatter, or both
BioTurf ships the same war on two fronts, and choosing between them is mostly a question of how hard your yard works.
The spray — BioS+ liquid — is the eraser. It follows the same path the urine took: past the blades, through the backing, into the layer where smell actually accumulates. There it digests what it finds. If the yard has history, the spray is what deletes it.
The scatter — BioFill granular infill — is the shield. Poured from the pail and brushed into the fibers, the granules sit in the turf like sandbags: absorbing moisture as it arrives and locking down ammonia on contact. They hold through heat and moderate rain, and a plain water rinse reactivates rather than removes them.
A single measured dog on a patio patch usually needs only the eraser on a steady cadence. A daycare-grade run wants both: spray to reset the field, granules to defend it between Saturdays. That pairing is exactly what the Power Packs box up — concentrate, BioSiphon sprayer and a pail of granules in one order.
