I ordered there reef amphipods and was wondering would it be better for me to put into tank that I am adding more sand to sand bed, my refugium or a ten gallon that only has LR, 4 inch sandbed?
If you put them into a system without amphipod predators (hopefully like your refugium) and you have a reasonable amount of food available then they will multiply nicely for you. I keep mine in my refugium.
