I have a 29 gallon reef tank and would like to start using phosphate sponge, I have some here and have a question about its use.  First, how much would I use in a 30 gallon, it doesnt really say.  Second, it talks about a charge, discarding it after 2 days and then adding a new fresh bag if you want to keep it for longer then a month.  Do you do that?  Or just put it in for a month?  
THanks,
Josh
