Looking for advice to lower my phosphates. They are currently at .8/.9 using the salifert test. Nitrates are at 10. Alk is steady at 10, magnesium about 1350, calcium about 450, salinity .026. It's a 40 gallon AIO. I run filter floss, GFO, Carbon, poly pads, and a ton of saechem matrix. I also run a skimmer, algae scrubber, and uv steralizer 24/7. I dose nopox daily to control the Nitrates as they used to be around 60 and are holding strong around 10 since carbon dosing. I feed half a cube of mysis daily. Stock in the tank is a damsel, sixline, midas blenny, clownfish, mandarin, and a pygmy hawkfish. Then there are various inverts like crabs, shrimp, and snails. I feel like I have tried everything, I'm open to any suggestions. Thanks.
