Form my Lamprologus ocellatus (same fish) tank I do 50 % water change weekly.
They look better, they seem happier, they eat well.
My tap water is,
I use Carib Sea substrate in two tanks. One 15g and one 40 breeder house a total of
21 fish. If I had to I would prep the water before replacing it. But other wise I just drain the water,
treat the tank with Prime, and fill directly.
