I have an 80 rimless that’s been up and running for about 8 months. So far I’ve been hating it. It’s my first bare bottom and I’ve been struggling to keep consistent nutrient levels (which I know is how it’s goes for the first year or so BB). Anyway I am going to set up a small 5 gallon nano and I have some live rock in my sump that’s been curing for a few months that I want to use in my nano but given my poor water quality in my tank at the moment should I even use it or does it matter? I’m planning on using fresh mixed salt water and not taking any out of my tank. I want the nano to be completely separate from my 80 as I am trying a different salt.
