Quarantine Practices

[mark]

Going to get a couple of Banggai Cardinals and was going to set up a QT but looking like it's basically this transfer tank method.

Plan was to use a 15g (rather than my previous 33g QT with skimmer, etc), fill from display system and refill display with new SW. I'll throw in a heater and use a small HOB filter with some carbon mainly for circulation, PVC pieces for shelter. Could also do some LR as got lots in my sump that planning on removing anyway.

I'll siphon out uneaten food and waste but some questions:
-figure change out 1/2 volume, would every couple of days be okay
-how long to leave the fish in, 2 weeks and no signs of ich etc, then okay to add to display?
