what went wrong

Thanks War Dog

I had been running Phosguard so I didn't think it would be an issue, but it is running high @02.5. My question was, did removing 30lbs of established LR (in the tank for 2 years) would the coral that I placed in the tank two months ago have had time to establish itself, or did my tank crash because of it? Did doing a 75% water change suffice, and now I just need to let the tank cycle, or is there another problem.
