720ppm of Ca?!!!!
Sorry to hop in here but... How accurate is the hagen test? I've been using this kit for 6 months and my calcium levels are always 420 to 480(480 on average)using IO salt and weekly use of Coral-Vite and Tech I. And in my 20G (weekly 4g change) with 12 or so corals and 2 small anenomes maintains 440-460. Can anybody recomend the most accurate test out there for Cal and dkH? Or is this kit sufficient? Thx!!! ;)
