I converted an AIO from a FW planted tank to a Nem/zoa tank. Due to the design of the sump, it was impossible to completely drain the tank and ~1\2g of water was left in the back. I adjusted salinity and set up the tank using very old live rock from another system.
I haven't noticed any issues at all except for a massive diatom bloom, which isn't surprising given the silicon level below. The ferts I was dosing contained zinc, so it doesn't surprise me that the test reflects that.
Are any of these levels actually harmful? Everything else tested is great.
