I found a deal on a 50 lbs sack of food grade calcium hydroxide which is the same as any of the exepensive aquarium grade kalkwasser. I have been using nothing but this kalk for months and my aquarium us thriving. I will sell it for $3/pound. Either come by if you are local to Bellingham, or I can ship for an extra $5 handling fee plus actual shipping costs. Otherwise you are looking at close to $15/lb to buy this same stuff in fancy packages.
