Drip acclimation<< should be antywhere from 2 hrs up to 6. The more sensitive the invert, the longer the acclimation. The shrimp should be fine with the 2ish hours or so but for starts and other extremely sensitive inverts 4-6 is best.
Inverts prefer a salinity of 1.024-1.026. I keep mine at 1.025. 34
ppt if using a refractometer.
(post split for more exposure)
