Update: Pennywise passed away in the night. I'll have to bring his corpse back to Pet Co. so I can collect on his insurance. I feel awful.
did you treat it the day before you put the fish in? That's a huge difference from the OP stating he treated it several weeks before adding fish. there should be some color on the nitrate test, there will never be zero nitrates in a system. and a few weeks in a 75 with those type of fish would have seen a big spike in bad water quality before it sorted itself out for sure.I used bottled stuff for 3 days then add my fish, maybe he did the same.
Most kits don't have a reading that shows under 20, mine doesn't at least. By a few weeks the cycle would have likely sorted itself out.
Just a thought

True true. My knives survived but didn't grow on it while I was getting them onto pelletsOn top of that a CK can not survive on bloodworms.
