Green Brighty Neutral K

Liquid potassium fertiliser for planted aquariums, designed to correct potassium deficiency without raising pH or carbonate hardness (KH).

When potassium is insufficient, plant growth and photosynthesis can slow and leaves may yellow or bleach. Daily dosing helps maintain healthy growth and improves plant resilience in low‑KH setups.

Key Features:

• Supplies potassium (K) only — no nitrogen (N) or phosphorus (P).
• Does not increase pH or KH, suitable for soft-water aquariums.
• Intended for daily use as part of the Green Brighty dosing routine.
