hey thanks!!! exactly what i has hoping for and better. i'll have to see if this stuff exists locally in the big box HW stores. and since it might be in season, maybe i'll be in luck.
FYI - in case anyone's intersted, I originally used all southdown in my 220 gallon 1" sand bed 2+ years ago. dealing with a horrible algae breakout - b/c of high nutrient problems - im cleaning/cooking all of my LR and am thinking about changing out the sand bed since it most likely contains alot of the excess nutrients. maybe i'll just rinse it and top it off with some new sand.
thanks again!
