There was a really good post about this awhile back. Someone suggested that you could scoop out about 1/4 of the CC and replace it with aragonite sand (rinsed really good). Wait a week (so the good bacteria can seed the sand) and do it to another 1/4 of your CC. I was contemplating doing this because I have CC, but I vacummed today and had no cloudiness at all.
And before you ask how they got the sand to go to the spot you scooped out, there was a pic of a gallon milk jug, cut half-way and taped to some PVC
pipe. Then they would place the sand in the milk jug and it would go down the PVC
to whatever spot they chose. A very inexpensive but very reliable way of doing it !!
