i never tried sand except in saltwater, i have small river rock now, thinking of switching to sand probably this year for a more natural look
I use play sand from the hardware store. Never had a problem. Just make sure you wash it thoroughly to remove dust. If not it could take up to a month for your tank to clear
See that was my other thought my dovii has teeth that I think the gravel Is wearing down since he digs a lotAnother thing with cichlids to consider:
My hait has been growing some AWESOME teeth since I changed him to sand. He digs a lot, and I think the gravel was grinding his teeth down. He's looking mighty mean with teeth now. I don't think I'd want to get bit by him.
Why would you use playsand when you can get PFS?
Playsand is dirtier, less heavy, and has a smaller grain size. It kicks up more, clouds up the water easier, and gets in your filters much easier. There really is no up side to using play sand over PFS.
