Changing my substrate for C C to a finer grade.. (about time) have been too lazy.. its my 75gal.. The reason for change is that i notice a more cleaner stable tank in my 100 gal
(which has the finest grain sand i have ever seen)
Whats the best way to change the sand..?
I was thinking 50/50 over 2-4 weeks as i dont wanna lose too much beneficial bacteria..
anyone chime in if they have changed substrate with great success..
