I'm already dosing NOPOX, running GFO
and Carbon also... NO3
I think the GHA are coming from nutrients my rocks release... I recently bleached my rocks, cured/cycled them for 1 months, then rinsed them under saltwater, then put them back to the tank... GHA started 1 week after adding thoses bleached rocks. This is like if the GHA were feeding directly to the source (rocks) and the nutrients don't have the time to be released into the water column, so the readings are 0...
Anyways, I'm currently Doing two daily 25% water change, last one tonight...
For my Pagoda coral, the guy at the LFS
told me maybe the "Seachem Reef Dip" (I already have this product at home) could help it revive.
I'm also running my R420R 60W 16000K° LED
Lighting system for 8 hours total, including 4.5 hours at almost full power...
