I know I am supposed to come your way sometime as I have promised over and over, but the two little ones have been keeping a tight rein on me. If you have time to come my way sometime with a water sample we could check you calcium with my test kit. I recently learned the truth about bad test kits when I had a pH test kit go bad. Not so bad as to know the kit was bad, but enough to start wondering. (It always read 7.9 no matter how recently I had added some buffer). Got a new kit and it read 8.3. I am glad that I use the SeaChem reef buffer that will not let me shoot above 8.3 or I probably would have been through the roof. Glad to hear that despite the elevated levels things have not started dying off. Hopefully, everything will come back in line without casualties. Let me know if I can help.
