Sorry to hear that Greg!! I know how you feel though.
FWIW, I ran a cyano treatment on my zeo tank some 2-3 weeks ago and it has helped. The cyano kicked back and hasn't reappeared. I've also discontinued all but the basic 4 of zeo for now and on Sean's advice I dialed back the flow through the reactor to a very small trickle.
I broke my reactor 2 nights ago trying to clear a rock jam. Luckily I had some weldon onhand to fix the acrylic, but now my reactor is starting to look more like Frankenstein between the gouges from rock jams and my acrylic fixit job. Not sure why I mention this, it's sort of irrelevant I guess.. .just thought I'd share my story that had me all p!ssy about zeo a couple nights ago.
Are you tracking your tank temperature at all? I wonder if it's warming up a bit now that it's warmer outside.
