Potassium Phosphate is a key Macronutrient vital for plant growth. Potassium Phosphate should be used in conjunction with macronutrients N and K as well as with Micronutrient fertilizer.

Analysis: (KH2PO4 – 5.5%)
- KH2PO4 - Δppm/1pump/10gal = +2.9ppm 
- 1 pump, 2cc, contains 110mg dissolved KH2PO4 
- 1 pump per 10 gal raises KH2PO4 concentration by 2.9ppm

- Dose 1 pump per 10 gallons twice weekly. 
- Dose 1 pump per 10 gallons every other day for densely planted high-tech tanks with CO2 injection 
- If algae growth increases reduce dosage

Index dosage:
- Test tank water for dissolved nutrient content frequently and adjust dosage to maintain optimal dissolved nutrient content: 3-5 ppm dissolved KH2PO4 (0.5-1 ppm PO4)

Water changes: 
- Dose 1 pump per 10 gallons of new water before water changes. 

Analysis breakdown: (K – 2.0%) (P – 2.5%) (PO4 – 1.0%) 
- K, Potassium         - Δppm/1pump/10gal = +1.06ppm 
- P, Phosphorus       - Δppm/1pump/10gal = +1.32ppm 
- PO4, Phosphate    - Δppm/1pump/10gal = +0.53ppm

Keeping 3-5ppm dissolved KH2PO4 (0.5-1ppm PO4) is optimal for high-tech planted tanks with CO2 injection.

Keep KH2PO4 as a limiting factor for plant growth if algae occur.   Excess Nitrate and Phosphate Macronutrients can contribute to algae growth and dosage should be reduced if algae growth increases.
