How would you switch (move over) a reef tank?

[Mike-fish]

if im not mistaken lanthanum chloride is the chemical found in foz-down. you just add it at your filter sock/ floss and it binds to the phosphate taking it out of solution in the water so your filter media can snag it. then you just remove the filter media and replace with fresh

Anyone else successfully move a reef using eco rock?

[cuz]

my first upgrade i added 150lbs of dry base rock and transefferd 100% succesfully, second upgrade i added 200lbs of base rock to the previous rock and was succesfull again but now I'm fighting phos from lack of curing either time..

Cuz, how much phosphate are you measuring?
