Sand is a great substrate. A very well trusted source recommended the switch. I've had black sand in my 29 for over a year now with no problems. Plants are doing quite well. Hope this helps!:thumbsup:
This is very true! Fish that move or sweep through the sand will help keep algae in checkthough I've had algae everywhere else in my tank, it has never grown on my sand, I believe it's because the corys are like little brooms, always turning it over and over and never really giving algae a chance.
