Par meter help

That's the third person myself included reporting a bulk GFO problem. It could be you just did not prepare it for 24 hours in fresh salt water. Or it could be bad GFO. I recommend running carbon for 24 to 48 hours and then replace the carbon? Do some water changes and pull the GFO. See if things respond better.

I turned the GFO off! I will do a water change tomorrow
