Description

GH+ ONE PLANT is a fast-dissolving powder remineralizer for RO/RODI water, specifically formulated for planted aquariums. It raises general hardness (GH) with a 4:1 Ca:Mg ratio — a balance optimized for aquatic plant uptake — without affecting KH or pH. It does not contain potassium or micronutrients, which means it does not interfere with the calibrated dosing ratios of other fertilizers.

Key benefits

  • Ca:Mg ratio of 4:1 — optimized for aquatic plant requirements
  • Does not raise KH or alter pH
  • Potassium-free and micronutrient-free — no interference with fertilizer dosing
  • Fast-dissolving powder — easy to dose precisely
  • Safe for shrimp and sensitive fish
  • Available in 500 ml (powder)

When to use GH+ ONE PLANT

Use whenever RO or RODI water is used as the primary water source, or when the tap water GH is too low for aquatic plants (below 4–6 dGH). Particularly important in softwater regions where plants show signs of calcium or magnesium deficiency.

GH+ ONE PLANT vs GH+ ONE SHRIMP

GH+ ONE PLANT has a higher Ca:Mg ratio optimized for plant uptake. GH+ ONE SHRIMP is formulated with a different mineral balance suited for Caridina shrimp breeding. Choose based on whether plants or shrimp are the primary focus.
