How old is the aquarium?

How long has the phosphate been increasing? What did it start out at?

 

[smitten with ocean life]

none that i know of! its just above the bracket that i was told to run in :thinking-face:

Don't chase numbers if your tank is healthy and happy. Mine runs anywhere from .2 to .5 with no issues.

Exactly as above!

You could lower it with gfo. If you choose that route use about half the recommended amount starting as it strips PO4 pretty quickly. I mix a few spoons of gfo in with my carbon when I change it out. I mainly do it just to keep mine from climbing much higher than it is which is 0.3. This is my oldest tank. Still high by many peoples standards but coral are happy so I roll with it.

0.31 ppm vs 0.19 ppm is probably not life threatening.
