Hi everyone, looking for some advice. For the last several days, I have noticed that one head of my hammer coral is not fully opening (the other looks normal and happy). All other corals and fish look normal/happy. Recent changes to my tank:
- started regularly dosing BRS 2-part a couple of weeks ago
- began running GFO reactor last weekend which took my PO4 from 0.2 down to 0. I temporarily turned it off after a few days when it read 0.0. Chose to try GFO because of green algae on the rocks and building up on glass quite quickly. I know it is part of the process, but figured it could help bring down the PO4.
Parameters:
Alk: 9.4
Ca: 475
Mg: 1420
Ammonia: 0
Nitrite: 0
Nitrate: 13
PO4: 0.0
PH: 8.0
Tank has been up and running since January, but was moved about 1.5 months ago (used new sand). Generally do 20% WC every 2 weeks, Red Sea Blue salt. Thank you in advance for any advice!
