Added magnesium and ph dropped really low then added buffer please help please help!!!!!

[FlushForce5]

Please help!!!!!! I have a waterbox marine 60.2 36 gallon reef tank. The guy at the LFS said my mag was low so I dosed it for the first time ever yesterday. I didn’t check it until tonight a day after and the ph was so low. I added buffer and it went up again . One of my sps looks a little lighter. I also added copepods today for the first time. It’s also saying my phosphate is 0.00 when on Saturday it was 0.035. I add stability every day and use half of the amount of ab+ that is recommended. I do not have any fish just all inverts. Please help me, did I crash my tank and is everything going to die? First tank ever after moving it I let it sit for four weeks and dosed stability every day. LFS said it was good to go except mag.

I wouldn't be adding pH buffers. Your alkalinity will raise significantly. I expect the pH reading is bogus / dodgy test or something but just in case, read this;

What exactly did you add for magnesium?
