In a planted aquarium, fertilizers play a crucial role in ensuring healthy plant growth. Let’s explore the different types of fertilizers and their roles:

• 1. Liquid Fertilizers:

Liquid fertilizers are instantly available for plants to absorb through their leaves. They work well for plants that primarily absorb nutrients from their leaves rather than their roots.

• 2. Root Tabs and Capsules:
  Root tabs and capsules are compressed plant fertilizers in tablet or capsule form.
  They are buried beneath the substrate (gravel or sand) around the plant roots.
  These slow-release fertilizers gradually provide nutrients that the roots absorb.
• 3. Substrate Fertilizers:
  Substrate fertilizers stay near the roots and provide nutrients where they are needed most.
  They prevent deficiencies and promote healthy growth.
