Well to add more controversy... I use a oversized high quality UV sterilizer, rated for protozoa 180,000 microwatts. I ran the UV during a outbreak as well with great success.That’s great! How about the QT process? I like to do a medicated QT, and obviously can’t have any rocks or anything for them, just pvc but I wasn’t sure if it would be suffice
I've tried QT, it's a lot of work and unless you QT every single thing that comes into your tank your still taking a risk. The other downside is the stress on the fish. I found anthias and butterflies just don't respond well to QT(in particular TTM). As I've said before, I've lost more fish QTing then just adding them in it takes a special some one to QT well.
UV and buy from a reputable supplier is my go to now. If you do QT there is plenty of knowledgeable people on this forum.
