For a tank that is still in it's infancy and a two week old purchase, I wouldn't stress too much about it. Sounds like you have the water quality under control, but still add livestock slowly as a fishless cycle starts the process, but it really needs livestock present for the BB to really get established well.

the nitrates would have to be astronomical to kill a fish that rapidly.
My tank hovers around 20-30 ppm
of nitrate and has gotten as high as >100ppm once and I have not lost any critters due to high nitrate, even ones that are supposed to be very sensitive to nitrate, stars, shrimp, crabs, snails and they have all been doing great for going on 6-8 months.
and a reminder, it's the fish that are nitrate factories, not filters and any type of filter if not maintained properly will trap detritus and uneaten food and contribute to nitrates.
pre-filtering with socks or something and protein skimmers make a huge difference, but only if cleaned daily.
If the OP is not planning on keeping corals, he doesn't need to chase low nitrate numbers as hard.
I think that is one point that often is not made clear, while not perfect, fish can handle higher nitrates than corals can, yet it seems as if the majority of advice is made based on the idea of corals being present.
but I do agree there should be some
