> 3 dayIm not sure if its the shape of it or if its the purity or whatever ,but i used just a couple teaspoons for a very cloudy 5 gallon and it was clear in 45 minutes. Ive used other activated charcoal before any this one seems to be much more efficient .

Greater than one weekThese are fine, too fine for many uses. The small granular pieces are small for my filter.

> 3 dayPriced competitively and I am able to leave it in my sump longer than other brands. More time enjoying the tank rather than maintaining it which can be tiresome. With all the upkeep required for a successful reef tank, Ill gladly pay a little more for less maintenance.
