Thanks for the advice, everyone. I'll set up a QT tank this weekend. Gonna grab a small heater and an air pump. Any tips for keeping the water stable in a small QT?

Just got some new Zoanthids and a Duncan from my LFS. They look healthy but I've heard mixed things about quarantining. My tank's a 40-gallon with a pair of Clowns, a Cleaner Shrimp, and some softies. Running a Fluval 307, salinity at 1.025, temp 78. Should I set up a QT or just dip and add?
