I am going to set up a 20 gal tank that I bought. It has been up and running for 1 yr. I have a 5 gal of LS I bought on the forum. My question is do I rinse the sand and seed it with some of the sand that came with the tank ( it was very over run with algey) If I do , how do I clean the sand. I'm sure there will be more questions. Thanks Dannie
