Thanks Jan. A PH crash is unlikely, but I'll check. I have crushed coral in
both filters.

I was treating for parasite/fungus a few weeks ago with PP. The third
treatment did seem to knock back the problem, but did not cure it. so I
started feeding Medi-Gold to cure what I think is a recurrent Columnaris
problem. I was concerned about killing the filters with the PP, so I was
rotating the filters (on/off) between treatments.

How did you detox the PP? Or did you? Even when water is brown there can
still be active PP in the system.

I did not see any Ammonia
spikes after the PP treatments. Last week when I started feeding the
Medi-Gold I started to see a drop in Nitrates. I thought this was the change
in food, but I should have clued in that the Cycle was dead. DOH!

I did a 50% water change again today and the Ammonia is still 1, so I don't
think the Ammo-Lock is doing much. I may do another change tonight or
tomorrow to bring the Ammonia down to .5 and keep it there (or less) until
it falls back to zero.

Are you using the 2 bottle salicylate tester kit? With a 2 bottle tester
and using Ammo-lock or similar product, your ammonia should read zero, it
is still there, but in the non-toxic form. The water change, if the pH is
higher than the tank, could make untreated ammonia more toxic.

I don't believe the Medi-Koi could do in the filter. ~ jan
