I have my quarantine tank next to my show tank. Although everyone says you don't need to add live sand and rocks I have them anyway to supplement my hanging filter. Fish fells at home with it and yes I add the PVC
pipe too. I still have plans to add more fish in main tank and right now my Blue Yellow Tail Tang is recovering with a daily dose of coppersafe treatment for 2 weeks. He will be back to real home for may be another week. You will never know when any of your fish gets sick. The emergency room is always ready for them.
