Why APT?
APT 1 replicates APT 3's winning formula without nitrates and phosphates. This provides maximum algae control for new tanks (we recommend starting all tanks with APT 1 for the first 1–3 months) and optimal long-term performance for tanks with higher fish populations, where fish food and waste already supply natural phosphates and nitrates.
