turning saltwater aquarium to freshwater
Hi I recently received an aqurium that was used in a saltwater set up. However it is too expensive for me to use it as a saltwater tank and I want to transfer it over to freshwater. The filter model is a Pro RS800G external filter and it has not been used in a very long time so I don't know if it works properly. I also have no idea if I can even still use the filter and if I was even able to I have no experience with this type of filter watsoever. So could someone please help me out here?
