Recently about 4 months ago I rid one of my 10 gallon tanks due to an intestinal parasite outbreak that damaged alot of my blood fin tetras. I washed the sand/eco complete substrate with just normal tap water and let it sit in the sun to dry. I stored it outside through out the winter months. Should I soak it in some kind of bleach concentration solution before reusing it in a new tank setup? If so any further guidance in how?
