When I ordered my PC lights from Captive Reefs, I also ordered a seachem calcium test kit. The first time I tested my water I'm pretty sure I messed up because my levels would have been over 1500, so I just quit the test, and went to test it again today. I opened my kit and I have misplaced the directions. Does anyone have a sechem calcium test kit that could tell me the instructions? pleeeeease
