Is the shock and swim powder 5 1 pound packages like the title says or 10 1 pound packages like the description says ?
9 oz. of Fiber Clear is teensy-tinsies-weensie! Don’t these things normally come in 7 or 25 lb. bags? Assuming my conversion calculation is correct, I would need two 9 oz. bags to recharge my filter instead of the 9 lbs. of D.E. I usually use. Considering that I get 25 lbs. of D.E. for about $20, that’s sort of expensive.
