So after some testing neglect, I've discovered my phosphates hitting a .35 with the Hannah Phosphorus checker and I'm attempting to drop it now. The problem is, whenever I seem to add GFO to the system to drop the phosphates, my sps seem to get burnt tips and are not happy. Testing my alkalinity shows 7.5 consistently with my doser keeping it in check, again with a Hannah tester. Do I just keep grinding through the phosphate drop with GFO until it's at an appropriate level, then change/use less to maintain? I've used GFO before but never seem it affect my SPS like this... My nitrates are around 5ppm at the moment if that helps.
Thanks,
