Just wondering if there is any danger in running GFO 24/7 in a reactor? Currently doing so in my mixed reef. Mostly concerned about my SPS. I've heard it might be better to run just a few hours each day.

nothing good about gfo in SPS tanks. it only causes your alk to swing.
Disagree.
24/7 here for several years.
No need to agree or disagree. For others want to prove it. Just Test alk right before adding new gfo and 2 days later. See it for yourself. It's is your tank. And dont stop auto alk dosing if you have it. There is a lot of conflicting info about gfo and carbon stuff. You just have to test and observe your corals. I know for sure bc I am obsessed with water testing, and t happens in my tank Every Single Time.
