Looks like everyone agrees that it is a Button Polyp

But now I have another problem? I have had a dwarf angle several crab's & all my pod's die in the past week? I hade thought that it could have been from the white smoke like stuff from the polyp? I just had to remove most of my micro algae in my fuge because it also turned a light brown color and was also not growing?
Here are my current water specks again: PH = 8.2 / ALK =3.5 MEQ/L / PO4 = 0.3 / NO2 = 0 / NO3 = 2 / NH3 = 0 / SG = 1.025 / Temp 82 degrees / The Ca is low 340 I need to get a new Ca test kit before I try to raise it!
Have I over looked anything

Any ideas :idea:
