My bare bottom fish-less frag tank/coral QT has 0 nitrates and 0 phosphates. I am a believer in having some nitrates and phosphates for coral growth. I am now dosing nitrate but I am not sure how to raise phosphates to detectable levels on either a hanna or red sea test.
How would I get phosphates detectable in the water? Since there is no fish I don't really feed the tank much.
