I've been keeping CRS and Dream Blue Velvet shrimp successfully for 3 years in a high tech 55 gallon tank. I change 50% water weekly and premix it in a big bucket with salty Shrimp GH+ and pump it into he tank with an eheim pump. My question is, would it be possible not to premix the water but have a small bucket inside the tank with the salty shrimp minerals in it, pump the water into hat bucket and let it overflow into the tank. It would make water changes slightly simpler. Has anyone done this before?
