super high calcium or BS test kit

[jason604]

hey guys ive tested my calcium about 10x now and each time im getting a reading well over whats even on the chart for the API test kit... if i were to guess it would be over 600-640.... my tank is about a lil over a month old now and i have quite a bit of corals so they should be draining my calcium lvls and all i did was put 2 caps of purple up in total... is my calcium lvl really that high or is API test kits just a piece of shyt? Cuz i know it reads my ammonia lvl as 10 when i have 0..
