Tank crash

[Ram3500]

Thanks for the feed back guys. I always read about tank crashes but this is my first one. I have been reefing for five years so it was bound to happen . Two date I have lost ten sps and five lps in the past two week. It just leaves me shaking head the worst part of it all was it was self inflicted . I had some pail sps so I started big water changes but I am guessing the Instant Ocean reef crystals was off . I don't understand how els my magnesium could drop 1300 to 800 in two weeks . Just a couple of weeks ago everything was just popping and everything looked so sweet and then BAM. As of today I have the mag back up to 1000 all other parameters are good even my nitrate is down to .10
I plan on doing a 45 gal water change every other day until things settle down . And to top it all off there is a dam mole digging up my newly sodded front yard . I really hope I can save my zoa garden and my monti caps if they die I think I gona get a bad ass trigger and call it a day
