PO4 issue

[MikeyZo]

So did a water change today, switching out from Imagitarium to Nutra-sea. I tested the NS water and the PO4 was 0.0. So I’ll see what the tank reads tomorrow. The PO4 phyto should be delivered tomorrow and Im looking to see if I can score some rowa phos nearby before I go online. I’ll keep updated.
