I’ve tried everything to lower my phosphate and I can’t. I am running cheminpure elite. And brightwell phosphate export. Im stuck at 1.5. Everything is fine and after a bunch of work my coralline is coming back. Is it possible to have corralline and phosphate at this level. Barely any algae in tank. Coral is fine. Fish are fine. I’m don’t know what’s going on. Any tips? Nitrate are at 12
