2 things I always consider a myth in reef keeping 0 NO3 and 0 PO4 in a flourish reef .....
I recently installed a koralin nitrate reactor few months ago bc my work and family is keeping me pretty occupied and I was lack in doing frequent water changes.....
I never tested my nitrates since I installed the reactor until this morning ....

It reads 0.... I hve never seen this in my entire reef keeping time ....
