Hmmmmmmm, never used that one Dennis, I use the Fastest which has a lowend of 2 I believe.If the lowests reading is 12.5 meq/l then a positive reading isnt a good one for a reef.My bad, the Fastest is 10 mg/l as the low reading, SO a positive reading calls for finding out why, I would apply the same logic to the Tetra kit, assuming the readings are somewhere near right.
