Yeah if you’ve been doing it then it’s fine. Just something to think about because people add gfo after having a algae outbreak or something and then it can have those affects. Going from high phosphates down to almost 0 will cause Corals to close up. That’s why I brought it up.
I been running GFO for a couple years and never had an issue ;Spiderman
