How bad is it if phosphates are 0.00?? I have fish and coral in a 40g breeder with a 20g long sump that has chemi pure elite, phosguard (which I just removed because previously my phosphates were 0.06…removed it since they’ve bottomed out), Purigen, filter socks, skimmer, and refugium with chaeto. Set up in August, cycled since September. Here’s the rest of my parameters: 9.5 alk, 11.6 nitrates, 1.025 salinity, 463 calcium (yes, I know it’s a little high), 1390 mag, 8.3 pH. Not sure what I should do now. Any advice?? Should I remove the chemi pure elite? Should I dose phosphates?
