Clarifier

Clarifier works like a gentler cousin of flocculant: instead of clumping particles heavy enough to sink to the floor, it coagulates them into clusters just large enough for the existing filter to trap during normal circulation, no vacuuming to waste required. It's the right tool for water that's slightly hazy rather than seriously cloudy, and it works over a day or two of normal filtration instead of overnight. Clarifier can't fix water that's cloudy because of a chemistry imbalance or an undersized filter cycle, so it's worth confirming chlorine, pH, and turnover time are already in range before reaching for it.
