Clarity® is a flocculant, meaning it bonds to small particles, making them much larger and easier to filter from the water. This will make the cloudiness worse for a short time until the large particles are removed from the water. Mechanical filtration is the only way to remove them, and if you don't have adequate mechanical filtration it will probably never clear. Typically, sponge filters are not fine enough to remove the larger particulate matter from the water. We recommend using Filter Floss in your filter and it may need to be changed several times before the water completely clears, as it will get saturated or become clogged.
