Somewhat rhetorical I think.

I was cleaning the boys yesterday (pond refugees) and I noticed that their
Ammo-Alert was far from it's pale yellow. It was up in the danger zone, so I
tested with the Ammonia kit and it was reading around 400. YIKES. So I did a
water change and added all the Ammo-Lock I had. I also added some Stress
Zyme, but I've never had much luck with this in the past. I'll keep doing
daily water changes and replacing the Ammo-Lock until I get things going
again,

Any advice appreciated.
