I am taking down my 30 gallon and setting up a 10 and 20 gallon. can i use the sand that is in the tank right now?
just tested my tank and my nitrate is 5Sorry not saying you cannot but used sand seems to be full of nitrates not sure how effective washing would be I would only ever use fresh sand as I have had bad experiences with used sand.
