So I'm looking at completely redoing my tank and was wondering A) will I be losing any important bacteria that I will need to be aware of/that I will need to compensate for in some way (and if so, how)? And B) does anyone have any recommendations. Looking to bring out color as well as something easy to keep clean and keep fish healthy (I have Jack Dempsey cichlids, EBJD, paratilopia bleekeri and green terror)
