What's up everybody? I have a few questions. How easy is it to change from a crushed coral substrate to sand? The tank (60 gallon marine uniquarium) just hit it's 5th week of operation. Will changing the substrate have a negative effect on the system overall? What would you recommend as a process to make this happen? I know I should of planned better, but at this point there is nothing I can do to reverse my original decision. Any advise is appreciated. Thank you in advance.
