The 2Hr Aquarist APT F Fix

Smart algae treatment for BBA, hair/string/fuzz and most forms of filamentous algae. Gently biodegrades completely.

APT FIX contains a proprietary mix of epoxy aldehydes. The dialdehyde components are protein crosslinkers that deactivate algae cells by binding to their proteins. The active component activates in water, but is quickly broken down by biological microbial action, resulting in no bio-accumulation in the aquarium ecosystem in the long run. This enables APT FIX to be a safe and effective inhibitor for various freshwater algae.
