Phosphorus is one of the three macro nutrients (NPK) required by plants. It is a component of ATP, NADP, nucleic acids and membrane phospholipids. Phosphorus is mobile in plants; this means that the plants divert these nutrients from older leaves to newer leaves. Thus, deficiency symptoms appear in older leaves first. Deficiency symptoms include dark, dull, or discolored leaves.
activateâ¢ is a concentrated (6,000 mg/L P) phosphorus source. When used as directed, activateâ¢ will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit, use with synthesisâ¢.
activateâ¢ is made with potassium salts of various phosphates, and is therefore a source of potassium as well. It contains 8,800 mg/L of potassium.
Sizes: 150 mL, 350 mL, 1 L, 4 L
Use 5 mL per 680 L (180 US gallons) twice a week (or as needed). This dose increases phosphate by 0.15 mg/L, and potassium by 0.06 mg/L.
When used with aquavitro'sÂ® nitrogen supplement, synthesisâ¢ at the same dose (5 mL/680 L (180 US gallons)) both products provide nitrogen and phosphorus in a 5:1 N:P ratio.
For smaller dosing, use the included pipette. Filled to the base of the bulb, the pipette holds 1 mL.
