So far the losses have been minimal considering what happened. Your higher nutrients hypothesis could very well be what saved my sps and sanity as my no3 has been at 25 and my po4 was 0.20-0.25 (70-85 ppb)Spikes seem to be fine as long as nutrients aren't dangerously low. Otherwise, most spikes IME just harm color a bit. Spikes below 5 dKH can be brutal, and that could be more PH related as well.
Most people forget that it was once pretty common to run 15-20 dKH.
Chaswood, happy to hear you didn't lose much!
