The bottle of JBL Ferropol is not worthless. Please shake the bottle prior to using the fertilizer and apply it the same way you did in the past. Our fertilizer has a relatively high concentration, so that individual nutrient salts may form crystals in exceptional cases. As soon as they are in the tank water, they dissolve again and are then as effective as before. The chelated fertilizer components are not affected by this.
The colouring of Ferropol depends on the pH value. During production Ferropol is set to a pH of 4.5. Then the colour is olive green. During longer storage and especially when the bottle has been opened, oxygen from the air gradually penetrates the fertiliser, the pH rises and changes the colour towards a brown tone. This has no influence on the effectiveness of the fertiliser and its ingredients. You can safely continue to use it.
