Terra Aquatica FloraMicro Hard Water 0,5l
Terra Aquatica FloraMicro Hard Water 0.5 litre is the foundation of the TriPart three-part nutrient system, specifically formulated for hard tap water containing more than 70 mg/L calcium. Unlike the Soft Water variant, this formulation accounts for the calcium already present in your water supply, preventing accumulation and nutrient lockout. FloraMicro delivers nitrogen, potassium and the complete package of chelated micro and trace elements: dual-chelated iron via EDDHA and PDTA, boron, manganese, zinc, copper and molybdenum. NPK 5-0-1 with integrated pH stabilisers for consistent solution chemistry. Essential from growth through bloom. The 0.5 litre bottle is the ideal trial format.
Terra Aquatica FloraMicro Hard Water 0.5L – The TriPart foundation for hard tap water
Hard tap water already contains significant levels of calcium and minerals — and your nutrient program must account for this. FloraMicro Hard Water is the foundation of the Terra Aquatica TriPart system, specifically formulated for tap water exceeding 70 mg/L calcium. Where the Soft Water variant adds supplementary calcium, the Hard Water formulation adjusts its calcium content to work in synergy with the minerals already in your water. The 0.5 litre bottle provides an accessible entry point for growers testing the TriPart system with their local water source.
Calibrated for your water type
FloraMicro is the only TriPart component that differs by water type. The Hard Water variant contains less calcium than the Soft Water version, as your tap water already supplies this element. This prevents excess calcium that can cause scale build-up, drip system blockages and antagonistic nutrient lockout. The remainder of the formulation is identical: NPK 5-0-1 with the complete micronutrient package.
- Nitrogen (N) 5%: 3.5% nitrate + 1.5% ammonium for balanced growth.
- Iron (Fe) 0.12%: dual-chelated EDDHA + PDTA for broad pH availability.
- Calcium (CaO): adjusted dosage that works synergistically with your tap water calcium.
- Trace elements: boron, manganese, zinc, copper and molybdenum — fully EDTA-chelated.
Dosage and mixing protocol
FloraMicro is used throughout the entire cycle, from first roots to final flush. Dosage in hydroponics: 0.5 to 2.0 ml/L. Always add FloraMicro first to the water — before FloraGro and FloraBloom. This sequence is critical to prevent flocculation.
The 0.5 litre format: test the TriPart system with your water
The 0.5L bottle is ideal for evaluating the TriPart system with your local tap water. Pair with 0.5L FloraGro and FloraBloom for a complete starter kit. Unsure whether your water is hard or soft? Check the calcium level with your water supplier — above 70 mg/L, choose this Hard Water variant.

When should I choose FloraMicro Hard Water over Soft Water?
Choose Hard Water if your tap water contains more than 70 mg/L calcium. This applies to many regions in Belgium, particularly in Flanders and Wallonia. The Soft Water variant is designed for RO water, rainwater or soft tap water below 70 mg/L calcium.
What happens if I use the wrong variant?
Using Soft Water with hard tap water risks calcium excess that blocks uptake of other elements and causes scale deposits in your system. Conversely, using Hard Water with soft water can lead to calcium deficiency. The correct choice makes a measurable difference in results.
Why must FloraMicro be added first?
FloraMicro contains calcium that can flocculate on direct contact with concentrated sulphates in FloraBloom. By diluting FloraMicro first in the water, you prevent chemical reactions and ensure a stable, homogeneous nutrient solution.
How do I determine if my tap water is hard or soft?
Check the water hardness with your local water supplier or measure the calcium content using an appropriate test kit. In Belgium, water hardness varies significantly by region. As a guideline: above 70 mg/L calcium choose Hard Water, below that threshold choose Soft Water.
