APT Fix is 100% fish, plant and shrimp safe if used as directed.
While healthy plant mass is the #1 natural defence against algae, life is often unpredictable.
The filter or CO2 diffuser gets clogged. Grandpa overfeeds the fish. The auto-timer takes an unannounced holiday.
These shocks ( seemingly insignificant to us) weaken plants and give algae a window of opportunity to spawn.
APT Fix works to rebalance the system by targeting the fundamental weakness of algae- their comparatively less developed protective cell walls. When spot-dosed per the recommended dosage, it instantly arrests algae growth while allowing plants to recover.
Most algae treatments use compounds that contain Copper, which is a powerful biocide.
The problem is that copper, like other heavy metals, accumulate over time and do long term damage to the tank's ecosystem.
APT Fix uses an active compound that biodegrades naturally within 24hours, with no nasty residues.
