7-in-1 Aquarium Test Strips — GH & KH, 100 Count

Seven parameters on one strip — GH and KH lead, with pH, nitrate, nitrite and chlorine alongside. Hardness is the parameter most planted and shrimp keepers ignore until something goes wrong; this makes checking it a 30-second habit.

• GH & KH matter.KH buffers pH stability; GH drives shrimp moulting and plant growth — now you can see both.
• Seven parameters per dip. One strip, one dunk, one read against the bottle chart.
• 100 strips. Weekly testing on two tanks lasts a year.
• Freshwater and marine. Works for both, plus ponds.
