Right around 50. I temp and drip acclimate (heater and pump in acclimation container), dip in Bayer, inspect visually, and sometimes cut them off the plug, depending on what it is and where it needs to go. Seems to work pretty well so far! (I recently added....well, 44 new pieces - HEY IT WAS A GOOD LIVE SALE and then ASD had a mega sale and STOP JUDGING ME hahahahaha)
