Fritz Crystal Clear - 236ml

Product overview

Fritz Crystal Clear is a liquid flocculant. It clumps fine haze — leftover food, bacterial bloom, gravel dust — so your filter pads can catch it, or so it drops to the sand for you to siphon.

It does not change pH and it does not add phosphate. Skimmers, UV, and reactors can stay on.

Key features

• Flocculant: Binds tiny particles so mechanical media can trap them.
• Chemistry: Does not shift pH or the biofilter. Phosphate-free.
• Gear: No need to shut UV, protein skimmers, or reactors.
• After: Rinse or replace wool, socks, or pads. They will be loaded with the clumped dirt.

Water and system compatibility

• Water: Freshwater, marine, reef, and ponds.
• System: Safe for fish, plants, corals, and invertebrates when used as directed. Can be used with other medications.
