{"product_id":"api-water-softening-pillow","title":"API Water Softening Pillow","description":"\u003cp\u003eA filter pillow that lowers general hardness — the calcium and magnesium content of tap water — for keepers of soft-water species who are working against hard supply water. It also takes out some heavy metals and reduces the mineral scale that builds up on glass and equipment.\u003c\/p\u003e\u003cp\u003eBe realistic about the duty cycle: one charge works for roughly 48 hours before it needs recharging, and the pillow can be recharged about four times before it is spent. That makes it a practical way to soften water for a change or for a small tank, not a set-and-forget fix for a large one.
