Have trouble with hammers

Also I agree with high nutrients can cause great coral growth because I used to have it for the longest time, phosphates were at ~2 ppm and nitrates ~30 ppm. I was able to fix the phosphate problem because it was my Rodi system so I basically had to replace all the components of it to fix it. So now I have low nutrients, which is not what I was aiming for.
