Woke up this morning to five dead Amanos and five others on the verge of death (pale, upside down, but still alive). Three others appear to be fine. Ammonia is 0 but nitrates are around 60 or so. I am EI dosing, so this doesn't seem to far out of line. Coincidentally, I bought some new plants that arrived yesterday and plopped them in yesterday. I noticed the shrimp zooming around as soon as I added them, but didn't think anything of it. Are there certain plants that are poisonous to Amanos?
