Total wipeout- ALMOST

[MartyG]

Something weird happened when the post came online. The numbers I gave added a 7 to them. The real numbers are:

Ammonia-0ppm
Nitrate -15ppm
Nitrite-0ppm
PH 8.6 (a bit high!)
Dissolved Oxygen-7ppm

That may help.
Anyway, I did another WC today and plan to leave it run for 3 weeks, doing more WCs and slowly restock.

Yes, heavy breathing, no scratching on the rocks, or spending a lot of time by the surface or return water.

sounds like something may have caused a problem with low oxygen.

maybe try creating more surface agitation?
