Thanks Mike and Daniel.
I dropped PO4 too low and am paying a small price with some minor bleaching and base recession. PO4 on the ULR reads 9 which for me is way lower than I usually run and this is after reducing PhosphateRx usage to 3 and now down to 2. PhosphateRx is strong stuff, keep out of reach of children. :lolspin:
I've dimmed my LED strips to slow things down a bit, monitoring KH daily.
NO3 - trace (salifert)
KH 7.2 (hanna), .67 (salifert)
2 drops PhosphateRx daily
2 drops MicroE
2 drops Kalum
Feeding aprox 1/4 tsp Reef Roids, Reef Chili, or Coral Frenzy every day.
Colors are improving on most corals, just need the bases to get healthy again.
