a freshwater tank and filters to convert them to a saltwater setup, also i have read a few articles that say i can use the same sand in my sw as i didnt in my fw is this true ? any suggestions would be great thank you.
The bacteria is not the same. You can wash it out real good and use it but if it was me I would just buy new sand. Rinse it and put it in the tank. But if you are thinking you would carry over the same nitrifying bacteria you wont.
You can view many of my fish and corals in my photo albums in my profile.
