Description

Dosing a planted tank properly means supplying nitrogen, phosphorus, potassium and a full range of trace elements. Doing that with separate bottles or dry salts means a schedule and a scale. An all-in-one puts everything in one bottle at ratios that work for the great majority of tanks.

Chelated iron (as EDTA and DTPA) stays available across a wide pH range, which is what actually determines whether red plants colour up.

Dosage

• Low light, no CO2: 2 ml per 40 litres, twice weekly.
• Medium light, no CO2: 3 ml per 40 litres, three times weekly.
• High light with CO2: 3 ml per 40 litres daily.

Contains

• Nitrogen (as nitrate), phosphorus (as phosphate), potassium
• Iron chelated with EDTA and DTPA
• Magnesium, manganese, boron, zinc, copper, molybdenum

Shrimp tanks

Safe at the stated dose. Copper content is low and chelated, but if you keep high-grade caridina, dose at half strength as a precaution.
