Sorry forgot to ask. Some folks are saying to only use half recommended copper meds. Also no sand or rock only pvc and control amonia with water changes. Sounds about right or what do u think? ThanksAs far as parasites go. The DT doesn’t need a water change. It needs to be fishless for min 45 days at 82 degrees with no cross contamination.
I would prioritize water changes on QT to fight ammonia.
