Composition & Analysis

Active ingredients. API’s own safety data sheet for Leaf Zone lists potassium sulfate (CAS 7778-80-5) at 6.2% by weight and EDTA-chelated iron (CAS 15708-41-5) at 1.2% by weight, in a water base: the manufacturer’s own figures behind the “chelated iron and potassium” the label already names.

What that means in the tank. As supplied it’s an orange-brown, slightly acidic liquid, pH 3.0 to 5.0, fully miscible with water.

Compatibility

API state Leaf Zone is safe to use with all freshwater invertebrates, including shrimp and snails, and that there’s no need to remove fish before dosing.

One caution from API themselves: Leaf Zone stimulates algae growth as well as plant growth, since both draw on the same nutrients in the water. Dosing at or under the label rate keeps that risk low; overdosing raises it.
