<strong>As someone already mentioned, it's kind of hard to answer this question without knowing what you mean whan you say the water is not "crystal clear".
Do you mean:
1) the water is discolored (yellowish or greenish)? If so, carbon would likely help.
2) You have micobubbles in the tank? Likely nees a skimmer/powerhead adjustment. All the carbon in the world won't help this.
3) you've got "stuff" floating around the water column. food, sand, just "stuff"? Use a filter floss for a couple days to remove it. Don't leave the floss too long, or it will become a biological filter (nitrate factory). The problem shouldn't come back.</strong><hr></blockquote>
I use charcoal off and on to clear up a yellowish tint to the water. I don't leave it in there and am reminded of using it once the water gets yellow again. SO... I was wondering in what amounts, how frequently, etc... one would go about administerring Ozone. But of-course I can use ye olde Search....
