Hi all, I'm new to the nano reef world and am planning a 15 gallon.


I have a question about sand. I don't have a lot of money and have heard that some reefers use southdown sand as a cheap alternative and then seed it with just a little bit of live sand.


I can't find southdown however, and am thus curious as to whether other sorts of sand would be suitable. I have used silica play sand from home depot in freshwater tanks without any problems. Would that sort of sand be ok in a nano also? or are there qualities specific to southdown that make it ok, that the other sand varieties won't have?


Are there any other cheap alternatives out there?


Any suggestions/answers will be greatly appreciated.


Thank you,

welcome to nr. calcium based sand will help buffer your water. skimping on a sw tank is not a good idea. all kinds of problems that you avoid if you set it correctly the first time.
