Am I preventing my substrate from becoming mature by doing my weekly gravel vacs? I'm just wondering, because when looking up some types of Neocaridina shrimp (cherry, bumblebee, mandarin shrimp) many sites said they required mature substrate. but doing gravel vacs wont stop it. Can anyone tell me what mature substarte means because i have been reading up on certain shrimp speices and it says that some of them.
