I have a new tank that was previously used as a saltwater tank that I will be using for freshwater. The tank still contains the sand substrait. Will I be able to use the sand for my freshwater setup or should I just dump it and get gravel or crushed coral? Also, is it a possible to go without substrait at all?
P.S. I have African Cichlids
Thanks
