well a reactor worked for me to say the least on my tank ( phosban reactor 150 ) with phosban media in it
I can littleraly take the phosphate test and nothing shows , and i accidently one night left the test vial on the table filled with the test the night before after sevral hours of sitting like that ' it barely had a reading at all , but i also run a refugium with a sand bed only and about 30 quarter halve dollar size clams, that helps with getting rid of nitrate as well |
